Description

  The present invention relates to a support structure that rotatably supports a first member with respect to a second member, and an electronic apparatus including the support structure.

  An electronic device including a lid member and a casing body is known. The electronic device includes a support structure that rotatably supports the lid member with respect to the housing body, and the opening of the housing body is opened and closed by rotating the lid member with respect to the housing body.

  An example of a related support structure is disclosed in Patent Document 1. Here, the support structure disclosed in Patent Document 1 will be described with reference to FIG.

  The support structure disclosed in Patent Document 1 is employed in a housing of an electronic device. As shown in FIG. 40, the housing 1 includes a lid member 2 as a first member and a housing body 3 as a second member. A recess 4 is formed in the housing body 3, and the opening of the recess 4 is opened and closed as the lid member 2 rotates relative to the housing body 3.

  The support structure employed in the housing 1 includes first and second shaft bodies 5 and 6 provided in the housing body 3, and first and second bearing portions 7 provided in the lid member 2. 8 and so on. A first fitting portion 9 is formed by the first bearing portion 7 and the first shaft body 5 inserted into the first bearing portion 7. A second fitting portion 10 is formed by the second bearing portion 8 and the second shaft body 6 inserted into the second bearing portion 8.

  The lid member 2 includes a lid main body (not shown) that covers the opening of the recess 4 and an insertion part (portion shown in FIG. 40) that is inserted into the recess 4. The first and second bearing portions 7 and 8 are formed in the insertion portion.

  In the support structure disclosed in Patent Document 1, the width of the lid body is substantially the same as the width M1 of the recess 4 in the axial direction of the rotation center axis. Furthermore, the width M2 of the insertion portion is smaller than the width M1 of the recess 4 with respect to the axial direction of the rotation center axis.

  By making the width M2 of the insertion portion smaller than the width M1 of the concave portion 4, a sufficient gap is formed between the insertion portion and the concave portion 4. Therefore, even when the position of the insertion portion is shifted from a desired position with respect to the lid body portion and the lid member 2 is manufactured, the lid member 2 can be easily disposed in the recess 4.

  By making the width of the lid main body portion substantially the same as the width M1 of the concave portion 4, there is almost no gap between the lid main body portion and the concave portion 4. That is, in the state where the lid body covers the opening of the recess 4, the opening edge of the recess 4 functions as a restricting portion that restricts the movement of the lid member 2 in the axial direction of the rotation center axis. As a result, rattling of the lid member 2 is suppressed.

Japanese Patent Laid-Open No. 06-302975

  However, in the support structure shown in FIG. 40, when the lid member 2 is rotated to open the opening of the recess 4, the opening edge of the recess 4 does not function as a restricting portion. Since the width M2 of the insertion portion is smaller than the width M1 of the recess 4, the lid member 2 rattles against the housing body 3 when the lid member 2 is opened. When the lid member 2 rattles against the housing body 3, the shaft body 5 may come off from the first or second bearing portion 7, 8, and the lid member 2 may fall off the housing body 3.

  An object of the present invention is to easily attach a first member such as a lid member to a second member such as a housing body, and to prevent the first member from falling off the second member. It is to provide a possible support structure and electronic equipment.

One aspect of the present invention includes first and second shaft bodies, first and second shaft body arrangement surfaces, first and second bearing portions, and first and second bearing portion arrangement surfaces. And a support structure comprising a first fitting portion and a second fitting portion. The first and second shaft bodies are provided on the first member and function as a central axis of rotation of the first member. The first and second shaft bodies are provided on the first and second shaft body arrangement surfaces, respectively. The first and second bearing portions are provided in the second member, and the first and second shaft bodies are inserted into the first and second bearing portions, respectively. First and second bearing portions are provided on the first and second bearing portion arrangement surfaces, respectively. The first fitting portion includes a first bearing portion, a first bearing portion arrangement surface, a first shaft body inserted into the first bearing portion, and a first shaft body arrangement surface. Composed. The second fitting portion includes a second bearing portion, a second bearing portion arrangement surface, a second shaft body inserted into the second bearing portion, and a second shaft body arrangement surface. Composed. The second fitting portion is a movement amount in the central axis direction of the first member relative to the second member according to the rotational position of the first member relative to the second member, but the amount of rattling is reduced. To do. One of the first and second members is a housing body having an opening, and the other of the first and second members is a lid member that opens and closes the opening by rotating with respect to the housing body. is there. The second shaft body arrangement surface and the second bearing portion arrangement surface are inclined with respect to the central axis, and the second shaft body arrangement surface is inclined when the first member and the second member are in the fully open position. And the inclination direction of the second bearing portion arrangement surface are different.

Another embodiment of the present invention relates to an electronic device including a support structure and an electronic component . Electronic components are housed in the housing body.

  Next, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
First, a first embodiment according to the present invention will be described with reference to FIGS.

  1 and 2 are perspective views of a housing provided with a support structure according to the present embodiment. As shown in FIGS. 1 and 2, the housing 11 includes a lid member 12 as a first member and a housing body 13 as a second member.

  The lid member 12 is rotatably supported by the housing body 13. An opening 14 is formed in the housing body 13, and the opening 14 is opened and closed by the lid member 12 rotating with respect to the housing body 13.

  1 shows a state in which the opening 14 is closed using the lid member 12 (also referred to as “closed state”), and FIG. 2 shows a state in which the opening 14 is opened (“fully open state”). Also called). Further, the first position of the lid member 12 shown in FIG. 1 is referred to as a “closed position”, and the second position of the lid member 12 shown in FIG. 2 is referred to as a “fully opened position”.

  Although not shown in FIGS. 1 and 2, a state in which the lid member 12 is rotated to some extent from the closed position toward the fully open position is referred to as a half-open state. The position of the lid member 12 in the half-open state is referred to as a “half-open position”.

  3A is a top view of the housing 11 in the closed state, and FIG. 3B is a side view of the housing 11 in the half-open state. As shown in FIG. 3, the support structure includes first and second fitting portions 15 and 16. The 1st and 2nd fitting parts 15 and 16 are demonstrated in detail using FIG. 4 thru | or FIG.

  4A, 4B, and 4C are a rear view, a top view, and a side view of the lid member 12, respectively. FIG. 5 is a perspective view of the housing body 13, and FIG. 6 is a top view of the housing body 13. FIG. 7 is an exploded top view of the housing 11.

  As shown in FIGS. 4 to 7, the housing body 13 includes first and second inward surfaces 17 and 18 facing each other, and an insertion space 19 is formed between the first and second inward surfaces. Has been. First and second bearing portions 20 and 21 are disposed on the first and second inward surfaces 17 and 18, respectively. The first and second inward surfaces 17 and 18 are also referred to as first and second bearing portion arrangement surfaces, respectively.

  The lid member 12 includes an insertion portion 22 formed to be insertable into the insertion space 19. The insertion portion 22 includes a first outward face 23 that faces the first inward face 17, and a second outward face 24 that faces the second inward face 18. First and second shaft bodies 25 and 26 are disposed on the first and second outwardly facing surfaces 23 and 24. The 1st and 2nd outward surfaces 23 and 24 are also called the 1st and 2nd shaft body arrangement | positioning surface, respectively.

  The first shaft body 25 extends from the first outward surface 23 toward the first inward surface 17 and is inserted into the first bearing portion 20. The first fitting portion 15 (see FIG. 3) includes a first bearing portion 20, a first inward surface 17 (first bearing portion arrangement surface), and a first bearing portion 20 inserted into the first bearing portion 20. The shaft body 25 and the first outward surface 23 (first shaft body arrangement surface) are configured.

  The second shaft body 26 extends from the second outward surface 24 toward the second inward surface 18 and is inserted into the second bearing portion 21. The second fitting portion 16 (see FIG. 3) includes a second bearing portion 21, a second inward surface 18 (second bearing portion arrangement surface), and a second bearing portion 21 inserted into the second bearing portion 21. The shaft body 26 and the second outward surface 24 (second shaft body arrangement surface) are configured.

  The first and second shaft bodies 25 and 26 are inserted into the first and second bearing portions 20 and 21, respectively, so that the lid member 12 is attached to the first and second shaft bodies 25 and 26. It is supported by the housing body 13 so as to be rotatable about the central axis of rotation based on the rotation. In other words, the first and second shaft bodies 25 and 26 are arranged along the central axis of rotation.

  The insertion portion 22 is shorter than the insertion space 19 on the rotation center axis (hereinafter also simply referred to as “rotation center axis A”), which is the rotation axis of the lid member 12. Specifically, the insertion portion width L1 between the first and second outward faces 23, 24 is the insertion space width L2 between the first and second inward faces 17, 18 on the rotation center axis A. Narrower than. Therefore, the lid member 12 can move in the axial direction of the rotation center axis A on the rotation center axis A with respect to the housing body 13, and rattling occurs. The backlash amount means the amount of movement of the lid member 12 relative to the housing body 13 in the axial direction of the rotation center axis A at a predetermined rotational position of the lid member 12.

  Further, the second fitting portion 16 has a specific position on the rotation center axis A of the lid member 12 in the second fitting portion 16 according to the rotational position of the lid member 12 with respect to the housing body 13 and the housing. The distance in the direction of the rotation center axis A from the specific position on the rotation center axis A of the main body 13 is varied.

  In the present embodiment, the first inward surface 17 and the first outward surface 23 in the first fitting portion 15 are formed substantially perpendicular to the rotation center axis A, and the second in the second fitting portion 16. The inward surface 18 and the second outward surface 24 are inclined with respect to the rotation center axis A. By forming the first and second fitting portions 15 and 16 in this way, the second fitting portion 16 is configured to have a specific on the rotation center axis A of the lid member 12 in the second fitting portion 16. The distance in the direction of the rotation center axis A between the position and a specific position on the rotation center axis A of the housing body 13 can be made different.

  This will be described more specifically.

  In the description of this document, the “inclination direction” of a predetermined surface refers to the predetermined surface in a direction perpendicular to the rotation center axis when the predetermined surface is inclined with respect to the rotation center axis. Means the direction in which the angle between and becomes the maximum. The “inclination angle” of the predetermined surface means the maximum angle at that time.

  Consider a state in which the opening 14 of the housing body 13 is closed using the lid member 12 (closed state). In the closed state, the angle formed between the second inward surface 18 and the rotation center axis A is the same as the angle formed between the second outward surface 24 and the rotation center axis A (that is, the inclination of the second inward surface 18). And the inclination angle of the second outward surface 24 is the same). The lid member 12 is positioned with respect to the housing body 13 so that the inclination direction of the second inward surface 18 and the inclination direction of the second outward surface 24 are the same direction. In this case, the second inward surface 18 and the second outward surface 24 are in a parallel relationship.

  At this time, the distance between the second inward surface 18 and the second outward surface 24 is constant in the axial direction of the rotation center axis A. When the lid member 12 moves to the second inward surface 18 side and the second inward surface 18 and the second outward surface 24 come into contact with each other, the lid member 12 and the housing body 13 in the first fitting portion 15 Is the maximum, and corresponds to the difference between the insertion portion width L1 and the insertion space width L2 on the rotation center axis A.

  Further, consider a state (half-open state) in which the lid member 12 is rotated to some extent from the closed position toward the fully open position. In the half-open state, the angle formed between the second inward surface 18 and the central axis A is the same as the angle formed between the second outward surface 24 and the central axis A. Further, the lid member 12 is positioned with respect to the housing body 13 so that the inclination direction of the second inward surface 18 and the inclination direction of the second outward surface 24 are not the same direction. In this case, the second inward surface 18 and the second outward surface 24 are not in a parallel relationship.

  At this time, the distance between the second inward surface 18 and the second outward surface 24 is not constant in the axial direction of the rotation center axis A.

  For example, when the lid member 12 gradually goes from the closed state to the fully opened state, a part of the second inward surface 18 and a part of the second outward surface 24 come into contact with each other at a predetermined rotational position. Further, when the lid member 12 moves to the fully open state, a part of the second inward surface 18 and a part of the second outward surface 24 act. In addition, due to the action of the rotation shaft and the bearing portion, a specific position on the rotation center axis A corresponding to the second inward surface 18 and the rotation center corresponding to the second outward surface 24 in the direction of the rotation center axis A. The distance to a specific position on the axis A becomes longer.

  At this time, in the first fitting portion 15, a force acts so that the distance between the first inward surface 17 and the first outward surface 23 decreases in the direction of the rotation center axis A. Therefore, the amount of rattling of the lid member 12 with respect to the housing body 13 can be reduced. That is, the distance between the lid member 12 and the housing body 13 in the first fitting portion 15 is smaller than the difference between the insertion portion width L1 and the insertion space width L2.

  In the above description, the inclination angle of the second inward surface 18 and the inclination angle of the second outward surface 24 are the same, but it is not necessarily required to be the same angle. Even if the angle is deviated, due to the relationship between the inclination direction of the second inward surface 18 and the inclination direction of the second outward surface 24, if the inclination direction is the same, the amount of backlash is small and the inclination direction is different. In this case, the amount of rattling is increased.

  As described above, the second fitting portion 16 has a specific position on the rotation center axis A of the lid member 12 in the second fitting portion 16 according to the rotational position of the lid member 12 with respect to the housing body 13. The distance in the direction of the rotation center axis A from the specific position on the rotation center axis A of the housing body 13 is varied. In other words, the second fitting portion 16 is a movement amount in the central axis direction of the lid member 12 with respect to the housing body 13, but reduces the amount of rattling.

  The range of movement of the lid member 12 in the axial direction of the rotation center axis A and the ease of attachment of the lid member 12 to the housing body 13 are determined by the inclination direction of the second inward surface 18 and the second outward surface 24. Depends on the relationship with the tilt direction.

  By maintaining the position of the lid member 12 so that the inclination direction of the second inward surface 18 and the inclination direction of the second outward surface 24 are substantially the same direction, the first inward surface 17 and the first outward surface A sufficient gap is formed between As a result, the lid member 12 can be more easily attached to the housing body 13.

  Further, by moving the lid member 12 to a position where the inclination direction of the second inward surface 18 and the inclination direction of the second outward surface 24 are not the same direction, the amount of rattling is reduced, and the lid member 12 is The housing body 13 is less likely to rattle. As a result, the first or second shaft body 25, 26 becomes difficult to come off from the first or second bearing portion 20, 21, and the lid member 12 is prevented from falling off from the housing body 13.

  In the present embodiment, the housing body 13 further includes a restricting portion 27 that restricts the movement of the lid member 12. The restricting unit 27 restricts the movement of the lid member 12 at a position other than the closed position, and restricts the movement of the lid member 12 at the closed position in the axial direction of the rotation center axis A.

  By restricting the movement of the lid member 12 by the restricting portion 27, rattling of the lid member 12 in the closed position is suppressed. As a result, the first or second shaft body 25, 26 does not come off from the first or second bearing portion 20, 21, and the lid member 12 does not fall off from the housing body 13.

  Further, the second inward surface 18 and the second outward surface 24 are formed so that the inclination directions are not the same when the lid member 12 is in the fully open position. That is, in the fully opened state, the movement of the lid member 12 in the axial direction of the rotation center axis A is restricted using the second inward surface 18 and the second outward surface 24. Therefore, the lid member 12 is less likely to rattle, and the lid member 12 is prevented from falling off the housing body 13.

  The second inward surface 18 and the second outward surface 24 are configured such that, in the fully opened state, a part of the second inward surface 18 and a part of the second outward surface 24 are in contact with each other, and the amount of rattling is zero. More preferably, it is formed. With such a configuration, the lid member 12 in the fully open position does not move in the axial direction of the rotation center axis A, and the lid member 12 does not fall off from the housing body 13.

  Further, the second inward surface 18 and the second outward surface 24 have the same inclination direction in the half-open state (position in the vicinity of the closed position) in which the lid member 12 is rotated to some extent from the closed position toward the fully open position. It may be formed as follows. That is, in the half-open state in which the inclination direction of the second inward surface 18 and the inclination direction of the second outward surface 24 are the same direction, there is sufficient space between the second inward surface 18 and the second outward surface 24. A gap is formed.

  Therefore, after the user holds the lid member 12 in the half-open position where the inclination direction of the second inward surface 18 and the inclination direction of the second outward surface 24 are substantially the same, and after the second fitting portion is fitted, By fitting the first fitting portion, the lid member 12 can be attached to the housing body 13 more easily. Further, the lid member 12 can be easily detached from the housing body 13 by removing the fitting in the reverse order.

  Note that the position in the vicinity of the closed position may be, for example, a position where a finger enters the gap between the housing body 13 and the lid member 12 when the lid member 12 is held by hand. A position where the rotation angle θ of the lid member 12 with respect to the housing body 13 (see FIG. 3B) is 30 degrees or less with the closed position of the lid member 12 as a reference position is more desirable as a position in the vicinity of the closed position.

  In addition, the 2nd inward surface 18 and the 2nd outward surface 24 may be formed so that an inclination direction may become the same in a closed state. In this case, the lid member 12 can be attached to the housing body 13 at a position close to the closed state.

  Even in the closed state, it is more preferable that a sufficient gap is provided between the insertion space 19 and the insertion portion 22. Even when the lid member 12 is manufactured by shifting the position of the insertion portion 22 from a desired position by providing a sufficient gap between the insertion space 19 and the insertion portion 22, the lid member 12. Can be fitted into the opening 14.

  However, in this case, when the lid member 12 is rotated, the second inward surface 18 and the second outward surface 24 are subjected to the second force so that a force acts in the axial direction of the rotation center axis A. It is desirable to set the inclination angle formed by the inward surface 18 and the second outward surface 24 and the rotation center axis A in accordance with the gap between the insertion space 19 and the insertion portion 22.

  The surfaces on which the first and second shaft bodies 25 and 26 and the first and second bearing portions 20 and 21 are provided are not limited to the examples shown in FIGS. A modification of this embodiment will be described with reference to FIGS. 8 to 10 are exploded top views showing modifications of the present embodiment.

  As shown in FIG. 8, the first and second shaft bodies 25 and 26 are provided on the first and second inward surfaces 17 and 18, respectively, and the first and second bearing portions 20 and 26 are provided. 21 may be provided on the first and second outward faces 23 and 24, respectively. In this case, the first shaft body 25 extends from the first inward surface 17 toward the first outward surface 23, and the second shaft body 26 extends from the second inward surface 17 to the second outward surface 24. Extending towards.

  Further, in the example shown in FIG. 8, the first inward surface 17 and the first outward surface 23 are inclined with respect to the rotation center axis A. The inclination direction of the first inward surface 17 is different from the inclination direction of the second inward surface 18, and the inclination direction of the first outward surface 23 is different from the inclination direction of the second outward surface 24. is there.

  As shown in FIG. 9, the lid member 12 may include an insertion space 19 formed between the first and second inward surfaces 17 and 18 facing each other with respect to the axial direction of the rotation center axis A. . In other words, the lid member 12 may be the second member, and the housing body 13 may be the first member.

  In the modification shown in FIG. 9, the first and second shaft bodies 25, 26 are provided on the first and second inward surfaces 17, 18 of the lid member 12, respectively. The first and second bearing portions 20 and 21 are formed on the first and second outward faces 23 and 24 of the housing body 13, respectively.

  Also in the example shown in FIG. 9, the first inward surface 17 and the first outward surface 23 are inclined with respect to the rotation center axis A. When the lid member 12 and the housing body 13 are in a predetermined positional relationship, the first inward surface 17 and the first outward surface 23 are inclined in the same direction so that the inclination direction of the first inward surface 17 and the first outward surface 23 are the same. The inward surface 17 and the first outward surface 23 are formed. At this time, the second inward surface 18 and the second outward surface 24 are formed so that the inclination direction of the second inward surface 18 and the inclination direction of the second outward surface 24 are the same direction. ing.

  When the lid member 12 and the housing body 13 have a predetermined positional relationship, the first inward surface 17 and the first outward surface 23 are in a parallel relationship, and the second inward surface 18 and the second inward surface A parallel relationship with the outward surface 24 is obtained.

  In the modification shown in FIG. 10, the lid member 12 includes first and second inward surfaces 17 and 18, and the housing body 13 includes first and second outward surfaces 23 and 24. The first shaft body 25 is disposed on the first outward surface 23, and the second shaft body 26 is disposed on the second outward surface 24. The first bearing portion 20 is formed on the first inward surface 17, and the second bearing portion 21 is formed on the second inward surface 18.

  As shown in FIG. 10, the second inward surface 18 and the second outward surface 24 may be formed stepwise with respect to the first inward surface 17 and the first outward surface 23, respectively. . By forming the second outward surface 24 in a step shape, the second fitting portion 16 can be configured such that the central axis of the lid member 12 with respect to the housing body 13 according to the rotational position of the lid member 12 with respect to the housing body 13. The amount of movement in the direction, but the rattling is different.

  In addition, when the said 2nd shaft body arrangement | positioning surface and the said 2nd bearing part arrangement | positioning surface are planes, it is good also considering this plane as each arrangement | positioning surface. In addition, when the second shaft body arrangement surface or the second bearing portion arrangement surface is a curved surface, a plane in contact with the curved surface at the intersection of the curved surface and the rotation center axis may be used as each arrangement surface. Further, when the second shaft body arrangement surface or the second bearing portion arrangement surface has a stepped shape, planes including the corners of the convex portions or the concave portions of the steps are used as the respective arrangement surfaces. Also good.

  Next, a procedure for attaching the lid member 12 to the housing body 13 will be described with reference to examples shown in FIGS.

  In the present embodiment, the first shaft body 25 is shorter than the second shaft body 26. By making the first shaft body 25 shorter than the second shaft body 26, it is easier to attach the lid member 12 to the housing body 13.

  First, the user determines the position of the lid member 12 with respect to the housing body 13 so that the second inward surface 18 and the second outward surface 24 are substantially parallel, and the second bearing portion 21 The shaft body 26 is inserted. Thereafter, the user presses the second outward surface 24 against the second inward surface 18 and inserts the insertion portion 22 into the insertion space 19. By inserting the insertion portion 22 into the insertion space 19, the first and second outward faces 23 and 24 face the first inward face 17 and the second inward face 18, respectively.

  Consider a case where the insertion space width L2 is larger than the width L3 between the tip of the first shaft body 25 and the second outward surface 24 on the rotation center axis A. In this case, the insertion portion 22 can be inserted into the insertion space 19 without bending the lid member 12.

  Consider a case where the insertion space width L2 is smaller than the width L3 on the rotation center axis A. In this case, the insertion portion 22 can be inserted into the insertion space 19 by bending the lid member 12. Since the insertion space width L2 is larger than the insertion portion width L1, the insertion portion 22 is inserted into the insertion space 19 only by bending the insertion portion 22 relatively small.

  When the insertion portion 22 is inserted into the insertion space 19, the user moves the lid member 12 toward the first inward surface 17. At this time, on the rotation center axis A, the length of (L2-L1) is made shorter than the length of the second shaft body 26 so that the movement amount of the lid member 12 is the length of the second shaft body 26. It is limited to a shorter distance.

  Since the second shaft body 26 is longer than the first shaft body 25, the first shaft body 25 is inserted into the first bearing portion 20 while the second shaft body 26 is inserted into the second bearing portion 21. Is inserted. The lid member 12 is supported by the housing body 13 by inserting the first and second shaft bodies 25 and 26 into the first and second bearing portions 20 and 21, respectively.

  When the lid member 12 supported by the housing body 13 is rotated, the second inward surface 18 and the second outward surface 24 are not parallel. When the second inward surface 18 and the second outward surface 24 are not parallel, the second inward surface 18 and the second outward surface 18 are compared with the second inward surface 18 and the second outward surface 24 compared to when the second inward surface 18 and the second outward surface 24 are parallel. The distance in the direction of the rotation center axis A between the outward surface 24 is narrowed. Therefore, the amount of movement of the lid member 12 relative to the housing body 13 in the central axis direction is small, and the first shaft body 25 is difficult to be removed from the first bearing portion 20. As a result, the lid member 12 is prevented from unintentionally dropping from the housing body 13.

  The length of the first shaft body 25 is the same as that of the first inward surface 17 in the first fitting portion 15 in the state where the second inward surface 18 and the second outward surface 24 are in contact with each other. It is more desirable that the distance is greater than or equal to the distance from the outward surface 23 in the direction of the rotation center axis A. By doing in this way, the conditions which the 1st outward surface 23 does not leave | separate from the 1st inward surface 17 more than the length of the 1st shaft body 25, and the drop-off | omission of the cover member 12 from the housing body 13 are made. Further prevented.

  Next, the lid opening / closing mechanism provided in the housing 11 will be described with reference to FIGS. The lid opening / closing mechanism includes a stopper 28 fixed to the lid member 12, first and second stopper receiving portions 29, 30 that receive the stopper 28, and a support that supports the first and second stopper receiving portions 29, 30. Member 31.

  The stopper 28 protrudes from the lid member 12 toward the outside in the vertical direction of the rotation center axis A, and rotates together with the lid member 12 with respect to the housing body 13. Therefore, the stopper 28 passes through a circular path C centered on the rotation center axis A when the lid member 12 rotates with respect to the housing body 13.

  The first and second stopper receiving portions 29 and 30 are provided so as not to rotate with respect to the housing body 13. The first and second stopper receiving portions 29 and 30 protrude from the support member 31 onto the path C. Further, the first and second stopper receiving portions 29 and 30 are arranged at a predetermined interval along the rotation direction of the lid member 12.

  In the present embodiment, the first stopper receiving portion 29 and the second stopper receiving portion 30 are arranged in this order with respect to the direction in which the lid member 12 is opened (hereinafter referred to as “opening direction R1”).

  When the stopper 28 passes through the first and second stopper receiving portions 29 and 30 as the lid member 12 rotates, the support member 31 is stopped via the first and second stopper receiving portions 29 and 30. Press. For example, pressing the stopper 28 using the support member 31 is realized by providing the support member 31 with flexibility. That is, the support member 31 functions as a pressing member.

  Subsequently, the operation of the lid opening / closing mechanism of the housing 11 will be described with reference to FIGS. 11 to 13. FIG. 11 shows a closed state in which the opening 14 (see FIGS. 2 and 5) of the housing body 13 is closed using the lid member 12. FIG. 12 shows a half-open state in which the lid member 12 is rotated to some extent in the opening direction R1 from the closed state. FIG. 13 shows a fully opened state in which the lid member 12 is further rotated in the opening direction R1 from the half-opened state and the lid member 12 is rotated to the fully opened position.

  In the description of this document, the fully open position of the lid member 12 is a position where the stopper 28 is positioned on the opening direction side of the first stopper receiving portion 29 and in contact with the first stopper receiving portion 29. In the present embodiment, the position of the lid member 12 shown in FIG. 13 is the fully open position, but the lid member 12 may be further rotatable in the opening direction R1 than the position shown in FIG.

  11 to 13, only the casing body 13 is drawn as a cross-sectional view when cut along the XI-XI plane shown in FIG. 5, and the lid member 12 is drawn as a side view. Yes.

  As shown in FIG. 11, the first and second stopper receiving portions 29 and 30 and the support member 31 are not in contact with the lid member 12 and the stopper 28 in the closed state. Therefore, the support member 31 does not press the lid member 12 or the stopper 28.

  The force generated in the lid member 12 includes a force caused by the weight of the lid member 12, a frictional force between the first shaft body 25 and the first bearing portion 20, a second shaft body 26, and a second This is only the frictional force with the bearing portion 21. Therefore, the user can rotate the lid member 12 only by applying a relatively small force to the lid member 12.

  When the user rotates the lid member 12 in the opening direction R <b> 1 from the closed state, the stopper 28 contacts the first stopper receiving portion 29. Thereafter, when the user further rotates the lid member 12 in the opening direction R <b> 1, the stopper 28 presses the support member 31 through the first stopper receiving portion 29. As a result, the support member 31 bends and the support member 31 presses the stopper 28 via the first stopper receiving portion 29 (see FIG. 12).

  When the support member 31 presses the stopper 28 via the first stopper receiving portion 29, a pressing load is generated between the stopper 28 and the first stopper receiving portion 29. The pressing load is transmitted to the user via the lid member 12. The user can sense that the lid member 12 has approached the fully open position by feeling the pressing load.

  When the lid member 12 is further rotated in the opening direction R1 from the half-open state shown in FIG. 12, the stopper 28 passes through the first stopper receiving portion 29, and the lid member 12 moves to the fully opened position (see FIG. 13). In the fully open state, the stopper 28 is positioned on the opening direction R1 side with respect to the first stopper receiving portion 29, so that the amount of bending of the support member 31 is smaller than that in the half open state.

  Since the amount of bending of the support member 31 is reduced, the pressing force of the support member 31 on the stopper 28 is reduced, and the pressing load between the stopper 28 and the first stopper receiving portion 29 is reduced. When the user feels that the pressing load is reduced, the user can obtain an operation feeling (hereinafter simply referred to as “operation feeling”) for recognizing that the lid member 12 has rotated to the fully open position.

  In order for the lid member 12 in the fully open position to rotate in a direction opposite to the opening direction R1 (hereinafter, this direction is referred to as “the closing direction R2”), the support member 31 is bent and the stopper 28 is the first stopper. It must pass through the receiving part 29. In other words, when the lid member 12 rotates in the closing direction R2, a pressing load is generated between the stopper 28 and the first stopper receiving portion 29, and the rotation of the lid member 12 in the fully open position is suppressed.

  The support member 31 preferably has such a rigidity that it does not bend even if only the force due to the weight of the lid member 12 in the fully open position acts on the lid member 12. If the support member 31 has such a rigidity, the lid member 12 remains in the fully open position by releasing the force applied to the lid member 12 by the user when the lid member 12 moves to the fully open position. As a result, the state of the housing 11 can be held in the fully open state.

  According to the present embodiment, since it is not necessary to provide a relatively complicated lock mechanism for stopping the rotation operation of the lid member 12 in the middle, the components of the lid rotation mechanism can be simplified and the cost can be reduced.

  In the present embodiment, the second stopper receiving portion 30 is disposed at a position in contact with the stopper 28 on the opening direction R1 side with respect to the stopper 28 of the lid member 12 in the fully open position. Therefore, in order for the lid member 12 in the fully open position to rotate in the opening direction R <b> 1, the support member 31 must bend and the stopper 28 must pass through the second stopper receiving portion 30. Therefore, rotation of the lid member 12 in the fully open position in the opening direction R1 is suppressed.

  When the user rotates the lid member 12 in the opening direction R <b> 1 from the state shown in FIG. 13, the stopper 28 hits the second stopper receiving portion 30. At this time, the support member 31 presses the stopper 28 via the second stopper receiving portion 30, and a pressing load is generated between the stopper 28 and the second stopper receiving portion 30. The pressing load is transmitted to the user via the lid member 12. The user can recognize that the lid member 12 is rotating to the opening direction R1 side from the fully opened position by feeling the pressing load.

  When the lid member 12 further rotates in the opening direction R <b> 1, the stopper 28 passes through the second stopper receiving portion 30. When the stopper 28 passes through the second stopper receiving portion 30, the support member 31 and the first and second stopper receiving portions 29 and 30 are separated from the lid member 12 and the stopper 28, and the support member 31 does not press the stopper 28. .

  The pressure load between the stopper 28 and the second stopper receiving portion 30 is reduced by releasing the pressure applied to the stopper 28 using the support member 31. The user can recognize that the lid member 12 has moved from the fully open position to the opening direction R1 side by feeling that the pressing load has been reduced.

  In a state where the stopper 28 has passed through the second stopper receiving portion 30, the force generated in the lid member 12 includes the force resulting from the weight of the lid member 12, the first and second shaft bodies 25 and 26, and the first and second It is only a frictional force between the second bearing portions 20 and 21 (see FIGS. 5 and 5). Therefore, the user can rotate the lid member 12 only by applying a relatively small force to the lid member 12.

  Further, since the second stopper receiving portion 30 is provided, the user can obtain an operational feeling even when the lid member 12 is rotated in the closing direction R2 and the lid member 12 is moved to the fully opened position.

  The pressing load between the stopper 28 and the second stopper receiving portion 30 may be a load greater than the force that the user can apply to the lid member. By doing so, the lid member 12 does not open more than the state shown in FIG.

  In addition, the lid member 12 can be stabilized at the fully opened position by sandwiching the stopper 28 between the first stopper receiving portion 29 and the second stopper receiving portion 30.

  As shown in FIG. 14, the support member 31 is not located on the path C of the stopper 28 and does not have to bend in the fully opened state.

  However, as shown in FIGS. 11 and 13, the portion of the support member 31 adjacent to the first stopper receiving portion 29 in the opening direction R1 is located on the path C of the stopper 28 and the support member 31 is in the fully opened state. It is more desirable to bend. As a site | part adjacent to the 1st stopper receiving part 29 regarding the opening direction R1, the site | part between the 1st stopper receiving part 29 and the 2nd stopper receiving part 30 is mentioned, for example. When the support member 31 is bent in the fully open state, a pressing load is generated between the stopper 28 and the support member 31, and the rotation of the lid member 12 in the fully open position is further suppressed.

  The first stopper receiving portion 29 is configured such that the amount of bending of the support member 31 gradually changes when the stopper 28 presses the first stopper receiving portion 29 and when the stopper 28 moves away from the first stopper receiving portion 29. It is preferably rounded.

  By providing such roundness in the first stopper receiving portion 29, it is possible to gradually change the bending of the support member 31 according to the movement of the stopper 28. As a result, the instantaneous deformation of the support member 31 when the stopper 28 passes through the first stopper receiving portion 29 is suppressed, and the playing sound of the support member 31 is reduced.

  Of course, when the stopper 28 presses the second stopper receiving portion 30 and when the stopper 28 moves away from the second stopper receiving portion 30, the second stopper has such a roundness that the bending amount of the support member 31 gradually changes. The receiving part 30 may be tinged.

  Further, when the stopper 28 presses the first and second stopper receiving portions 29 and 30, and when the stopper 28 moves away from the first and second stopper receiving portions 29 and 30, the amount of bending of the support member 31 is gradually increased. The stopper 28 may have a roundness that decreases to a minimum. The stopper 28 and the first and second stopper receiving portions 29 and 30 may be rounded.

  In the present embodiment, only one stopper 28, first and second stopper receiving portions 29, 30 and support member 31 are provided, but a plurality of these are provided along the axial direction of the rotation center axis. It may be provided. By increasing these numbers, the user can obtain a stronger operational feeling and can further suppress the rotation of the lid member 12 in the fully open position.

  Further, a plurality of stoppers 28 may be provided side by side in the rotation direction of the lid member 12. By using the plurality of stoppers 28 arranged in the rotation direction, the lid member 12 can be stopped at a plurality of positions.

  Furthermore, in this embodiment, the support member 31 is provided in the housing body 13 and the first and second stopper receiving portions 29 and 30 are supported by the support member 31. However, the present invention is not limited to this form. I can't.

  The support member 31 may be provided on the lid member 12, and the stopper 28 may be supported by the support member 31. Further, the lid member 12 is made of a flexible member, the stopper 28 is provided on the lid member 12, and the first and second stopper receiving portions 29 and 30 are provided on the housing body 13. Good. In this case, a pressing load is generated when the lid member 12 is bent. In this case, the lid member 12 is an example of a pressing member.

  In the present embodiment, the movement of the lid member 12 in the fully opened state is suppressed. However, the present invention changes the positions of the stopper 28 and the first and second stopper receiving portions 29, 30 to change the closed state or the half opened state. It is also possible to suppress the movement of the lid member 12 in the state.

  According to the present embodiment, the lid member 12 remains in the closed position and the fully open position, but does not remain in the half open position. Therefore, the user holds the lid member 12 by hand until the lid member 12 moves from the closed position to the fully open position or from the fully open position to the closed position. That is, the movement of the lid member 12 in the half-open position is restricted by the user's hand. Accordingly, unintentional removal of the first shaft body 25 from the first bearing portion 21 is suppressed.

  When the lid member 12 is in the closed position, the movement of the lid member 12 in the direction along the rotation center axis A is restricted using the restricting portion 27 (see FIGS. 1 and 2). When the lid member 12 is in the fully open position, the first inward surface 17 and the first outward surface are in contact with each other, and the second inward surface 18 and the second outward surface 24 are in contact with each other. The movement of the lid member 12 in the axial direction of A is restricted. Therefore, unintentional removal of the first shaft body 25 from the first bearing portion 21 is suppressed regardless of whether the lid member 12 is in the closed position or the fully open position.

  Thus, according to the present embodiment, the first shaft body 25 is unintentionally removed from the first bearing portion 21 regardless of whether the lid member 12 is in the closed position, the half-open position, or the fully-open position. Is suppressed. Therefore, it is possible to prevent the lid member 12 from being unintentionally dropped from the housing body 13.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the same element as the element contained in the support structure and lid | cover opening / closing mechanism which concerns on 1st Embodiment, and the description is abbreviate | omitted.

  Here, a support structure applied to a projection display device will be described, but the present invention can also be applied to an electronic device other than the projection display device, for example, an electronic device such as a printing device or a terminal device.

  FIG. 15 and FIG. 16 are views when the projection display device provided with the support structure according to the present embodiment is viewed from the bottom side. For example, FIGS. 15 and 16 correspond to a state in which the projection display device is suspended from a ceiling or the like of a room and installed with the top surface and the bottom surface reversed.

  As shown in FIGS. 15 and 16, the projection display device 32 includes a housing body 13, a flexible lid member 12, and a projection lens 33. An electronic component 42 is accommodated in the housing body 13. Image light formed using the electronic component 42 is projected from the projection lens 33, and an image is projected on the screen.

  15 shows a closed state in which the opening 14 is closed using the lid member 12, and FIG. 16 shows a state in which the opening 14 is opened. For the sake of convenience, the state shown in FIG.

  In the present embodiment, the housing body 13 includes a side panel 13a, a bottom panel 13b, and a top panel (not shown). The lid member 12 is rotatably attached to the bottom panel 13b.

  FIG. 17 is a front view of the lid member 12. 18 is an enlarged view of the XVIII portion shown in FIG. 17, and FIG. 19 is an enlarged view of the XIX portion shown in FIG.

  As shown in FIGS. 17 to 19, the lid member 12 includes an insertion portion 22, a first shaft body 25 extending from the first outward surface 23 of the insertion portion 22, and a second outward surface of the insertion portion 22. And a second shaft body 26 extending from 24. The first outward surface 23 is formed perpendicular to the rotation center axis A, and the second outward surface 24 is inclined with respect to the rotation center axis.

  The first and second shaft bodies 25 and 26 extend in the axial direction of the rotation center axis A. The insertion part 22 has a cylindrical shape. The central axes of the first and second shaft bodies 25 and 26 and the central axis of the insertion portion 22 are located on the rotation center axis A.

  20 is a side view of the housing body 13 shown in FIG. 16 as viewed from the opening 14 side. FIG. 21 is an enlarged view of the XXI portion shown in FIG. 20, and FIG. 22 is an enlarged view of the XXII portion shown in FIG.

  As shown in FIGS. 20 to 22, the housing main body 13 includes a first bearing portion 20 into which the first shaft body 25 is inserted and a second bearing portion into which the second shaft body 26 is inserted. 21. A first inward surface 17 of the first bearing portion 20 facing the second bearing portion 21 side; a second inward surface 18 of the second bearing portion 21 facing the first bearing portion 20 side; Thus, an insertion space 19 is formed.

  The first inward surface 17 is formed substantially perpendicular to the rotation center axis A. The second inward surface 18 is inclined with respect to the rotation center axis A corresponding to the second outward surface 24 (see FIG. 19).

  FIG. 23 is a bottom view of the projection display device 32 in the closed state. FIG. 24 is a cross-sectional view of the projection display device 32 in the closed state cut along the XXIV-XXIV plane shown in FIG. FIG. 25 is an enlarged view of the XXV portion shown in FIG. 24, and FIG. 26 is an enlarged view of the XXVI diagram shown in FIG.

  As shown in FIGS. 23 to 26, the width of the insertion portion between the first and second outward faces 23, 24 is between the first and second inward faces 17, 18 on the rotation center axis A. It is narrower than the insertion space width. In the closed state, the second inward surface 18 and the second outward surface 24 are substantially parallel. Therefore, gaps G1 and G2 are formed between the first inward surface 17 and the outward surface 23 and between the second inward surface 18 and the second outward surface 24, respectively.

  In the closed state, the lid member 12 is fitted in the opening 14 (see FIG. 16). Therefore, the movement of the lid member 12 in the direction along the rotation center axis A is restricted, and rattling of the lid member 12 with respect to the housing body 13 is suppressed. As a result, the first and second shaft bodies 25 and 26 (see FIGS. 18 and 19) do not come out of the first and second bearing portions 20 and 21, respectively, and the lid from the housing main body 13 is removed. The member 12 is prevented from falling off.

  FIG. 27 is a bottom view of the projection display device 32 in a fully opened state. FIG. 28 is a cross-sectional view of the projection display device 32 in the fully opened state taken along the plane XXVIII-XXVIII shown in FIG. FIG. 29 is an enlarged view of the XXIX section shown in FIG.

  When the lid member 12 is in the fully open position, the lid member 12 is not fitted into the opening 14 (see FIG. 16). Therefore, the opening edge of the opening 14 does not restrict the movement of the lid member 12 in the axial direction of the rotation center axis A.

  As shown in FIGS. 27 to 29, in the fully opened state, the second inward surface 18 and the second outward surface 24 are not in a parallel relationship. A part of the second inward surface 18 is in contact with the second outward surface 24. Therefore, the movement of the lid member 12 in the direction along the rotation center axis A is restricted.

  Since the first and second inward surfaces 17 and 18 restrict the movement of the lid member 12 in the axial direction of the rotation center axis A, the lid member 12 is less likely to rattle against the housing body 13. As a result, the first and second shaft bodies 25 and 26 (see FIGS. 18 and 19) are difficult to come off from the first and second bearing portions 20 and 21, respectively. 12 is prevented from falling off.

  Note that the modification examples shown in FIGS. 8 to 10 can also be applied to the projection display device 32.

  Here, the lid opening / closing mechanism according to the present embodiment will be described with reference to FIGS. FIG. 30 is a plan view of the bottom panel 13b. Note that the side panel 13a and the lid member 12 are attached to the bottom panel 13b shown in FIG. 30, and the lid member 12 is in the closed position. 31 is a cross-sectional view of the bottom panel 13b and the lid member 12 taken along the XXXI-XXXI plane shown in FIG.

  As shown in FIG. 31, the lid opening / closing mechanism includes a stopper 36 provided on the lid member 12 and a support member 31 provided on the housing body 13. The support member 31 includes an arc portion 35 and a protrusion 36 provided at the tip of the arc portion 35.

  The arc portion 35 is formed corresponding to the path C of the stopper 36 when the lid member 12 rotates. The protrusion 36 is located on the path C of the stopper 36. Therefore, when the lid member 12 rotates in the opening direction R <b> 1, the stopper 36 comes into contact with the protrusion 36.

  Since the lid member 12 has flexibility, the lid member 12 bends when the stopper 36 contacts the protrusion 36. When the lid member 12 is bent, a reaction force is generated between the lid member 12 and the bottom panel 13b. That is, the lid member 12 functions as a pressing member.

  FIG. 32 is a view showing a state where the lid member 12 is rotated from the state shown in FIG. The lid member 12 is held by the lid member 12 and the bottom panel 13b being pressed against each other.

  When the lid member 12 further rotates in the opening direction R1 from the state shown in FIG. 32, the stopper 36 passes through the protrusion 36, and the lid member 12 and the bottom panel 13b are not pressed against each other. As a result, the lid member 12 is easily rotated.

  In order to allow the lid member 12 and the bottom panel 13b to be pressed against each other with a greater force, the stopper 36 is disposed between the first and second shaft bodies 25 and 26 (see FIG. 20). It is preferable. Further, the pressing force can be adjusted by changing the position and quantity of the stopper 36.

  FIG. 33 is an enlarged view of the protrusion 36. As shown in FIG. 33, the protrusion 36 includes first and second stopper receiving portions 37 and 38 arranged in the opening direction R1. When the stopper 36 (see FIG. 31 and the like) moves along the contours of the first and second stopper receiving portions 37 and 38, the user feels a reaction force.

  When the stopper 36 moves between the first and second stopper receiving portions 37, 38, the first stopper receiving portion 37 strengthens the reaction force of the stopper 36 in the closing direction R2, and the second stopper receiving portion 38 The reaction force of the stopper 36 in the opening direction R1 is increased. As a result, the rotation of the lid member 12 is further suppressed and held in a stable state.

  In the present embodiment, since the lid member 12 bends in a direction intersecting the rotation center axis A, the lid when the pressing load is applied between the lid member 12 and the housing body 13 or when the pressing load is released. Local deformation of the member 12 is suppressed. As a result, the playing sound when the lid member 12 moves to or from the fully open position is reduced.

  In the present embodiment, the protruding portion 36 includes the first and second stopper receiving portions 37 and 38, but the protruding portion 36 may not include the second stopper receiving portion 38. . In this case, only the rotation of the lid member 12 in the fully open position in the closing direction R2 is suppressed. When the protrusion 36 does not include the first stopper receiving portion 37, only the rotation of the lid member 12 in the fully open position in the opening direction R1 is suppressed.

  By changing the height of the first and second stopper receiving portions 37, 38, the magnitude of the reaction force of the stopper 36 in the opening direction R1 and the closing direction R2 changes. Further, by adjusting the distance between the first and second stopper receiving portions 37 and 38, it is possible to adjust the range in which the user feels the reaction force when the lid member 12 is opened and closed.

  In the present embodiment, as shown in FIG. 17, the lid member 12 is provided with a plurality of ventilation openings 39. For example, by using a fan (not shown) attached to the housing body 13 for sucking outside air, the outside air is sucked from the ventilation opening 39 when the lid member 12 is closed, and the inside of the projection display device 32 Can be cooled.

  Further, a filter that adsorbs sucked outside air dust and the like is disposed in the housing body 13 in the vicinity of the opening 14. It is desirable that the filter in the housing body 13 is periodically cleaned or replaced. According to the present embodiment, the lid member 12 can be kept in the fully open position (see FIG. 16), and therefore, operations such as cleaning of the filter in the housing body 13 are facilitated.

  In the present embodiment, the lid member 12 bends in the fully opened state. Therefore, the lid member 12 is easily detached from the housing body 13 in the fully opened state.

When the second inward surface 18 and the second outward surface 24 are planes perpendicular to the rotation center axis A,
X2 <X1 + X3
Under such conditions, the first shaft body 25 may come off from the first bearing portion 21.

  Here, X1 is a distance in the direction of the rotation center axis A between the lid member 12 and the housing body 13 in a state where the lid member 12 is not bent. X2 is the length of the portion of the first shaft body 25 inserted into the first bearing portion 21 in the direction of the rotation center axis A. X3 is the amount of reduction in the length of the lid member 12 in the direction of the rotation center axis A caused by the lid member 12 being bent.

  In the present embodiment, the second inward surface 18 is inclined with respect to the rotation center axis A, and the second outward surface 24 is inclined with respect to the rotation center axis A. Then, the second inward face 18 and the second outward face 24 are formed so that the second inward face 18 and the second outward face 24 are not in a parallel relationship when the lid member 12 is in the fully open position. ing.

  When the second inward surface 18 and the second outward surface 24 are not parallel, the second inward surface 18 and the second outward surface 18 are compared with the second inward surface 18 and the second outward surface 24 when compared with the parallel case. The gap G2 (see FIG. 26) between the outward surface 24 is narrowed. Accordingly, the movement range of the lid member 12 is narrowed, and the first shaft body 25 is difficult to be removed from the first bearing portion 20. As a result, it is possible to prevent the lid member 12 from unintentionally dropping from the housing body 13.

  Next, a procedure for attaching the lid member 12 to the housing body 13 will be described with reference to FIGS.

  FIG. 34 is a bottom view of the projection display device 32 in a half-open state. The first shaft body 25 is disengaged from the first bearing portion 20, and the second shaft body 26 is inserted into the second bearing portion 21. FIG. 35 is a cross-sectional view of the projection display device 32 in a half-open state when cut along the XXXV-XXXV plane shown in FIG. 36 is an enlarged view of the XXXVI portion shown in FIG. 35, and FIG. 37 is an enlarged view of the XXXVII portion shown in FIG.

  In the present embodiment, the first shaft body 25 is shorter than the second shaft body 26. By making the first shaft body 25 shorter than the second shaft body 26, it is easier to attach the lid member 12 to the housing body 13.

  First, the user keeps the lid member 12 in the half-open position, and makes the second inward surface 18 and the second outward surface 24 substantially parallel. Thereafter, the user inserts the second shaft body 26 into the second bearing portion 21 and presses the second outward surface 24 against the second inward surface 18 (see FIG. 37).

  Subsequently, the user inserts the first shaft body 25 into the first bearing portion 21.

  In the present embodiment, since the lid member 12 bends when the lid member 12 is in the fully open position, the insertion space width between the first and second inward surfaces 17, 18 is the tip of the first shaft body 25. And the width between the second outward face 24 and the second outward face 24. The user can insert the first shaft body 25 into the first bearing portion 21 by bending the lid member 12 when inserting the first shaft body 25 into the first bearing portion 20.

  More preferably, the chamfered portion 40 a is provided on the first inward surface 17, and the chamfered portion 40 b corresponding to the chamfered portion 40 a is provided on the first shaft body 25. The chamfered portions 40 a and 40 b function as a guide that guides the first shaft body 25 to the first bearing portion 20. Therefore, it becomes easier to insert the first shaft body 25 into the first bearing portion 20.

  The lid member 12 is supported by the housing body 13 by inserting the first and second shaft bodies 25 and 26 into the first and second bearing portions 20 and 21, respectively.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS. 38 and 39. FIG. In addition, the same code | symbol is attached | subjected about the same element as the support structure which concerns on 1st and 2nd embodiment, and the description is abbreviate | omitted.

  The present embodiment relates to a support structure used for the air conditioner 41. The lid member 12 corresponds to the front panel of the air conditioner 41. In the air conditioner 41, a front panel may be opened to clean a filter (not shown) in the housing body 13.

  As shown in FIGS. 38 and 39, the air conditioner 41 includes a housing body 13 and a lid member 12. An electronic component (not shown) is accommodated in the housing body 13.

  The air conditioner 41 removes dust and the like by, for example, passing outside air sucked from the vent 39 of the lid member 12 through a filter disposed in the housing body 13. The air conditioner 41 air-conditions the room in which the air conditioner 41 is installed, for example, by cooling or heating air from which dust or the like has been removed and discharging the air from an exhaust port (not shown).

  Since the air conditioner 41 includes the lid opening / closing mechanism, the air conditioning apparatus 41 can be held in a state where the lid member 12 as the front panel is opened (see FIG. 39). Therefore, operations such as cleaning the filter in the housing body 13 are facilitated.

  Also in this embodiment, the support mechanism according to the first embodiment is employed. Therefore, the lid member 12 can be easily attached to the housing body 13 and the lid member 12 can be prevented from falling off the housing body 13.
