  By the way, when using the package tray as described above, it is assumed that the user of the vehicle installs the package tray on the vehicle without attaching the package tray to the shaft portion from the state where the package tray is removed from the vehicle. Specifically, since the package tray is installed in the vehicle from the rear of the vehicle, the shaft portion may be arranged in front of the package tray in the vehicle.

  In such a state where the shaft portion is arranged in front of the vehicle of the package tray, in other words, in a state where the package tray is arranged behind the vehicle from the correct mounting position, the user tries to close the back door. In this case, the back door comes into contact with the rear portion of the package tray, the package tray is pressed forward of the vehicle, the package tray interferes with the shaft portion arranged in front of the package tray, a load is applied to the shaft portion, and the case is broken. Concerned. In order to further improve the performance of the package tray, it is required to suppress a situation in which a load is applied to the shaft portion even when the package tray as described above is not correctly attached.

  The present invention has been completed based on the above-described circumstances, and can suppress a situation in which a load is applied to the shaft portion even when the package tray is not correctly attached to the shaft portion. It is an object of the present invention to provide a tray support structure.

  In order to solve the above problems, a package tray support structure according to the present invention is a package tray support structure that rotatably supports a package tray provided in a luggage compartment of a vehicle with respect to a vehicle body side, A shaft portion provided on the vehicle body side and extending along a rotation axis of the package tray with respect to the vehicle body side; a bearing portion provided on the package tray to which the shaft portion is attached; and the bearing portion in the package tray. And a guide part that guides the shaft part to the bearing part, wherein the guide part is arranged in a state where the shaft part is arranged in front of the package tray. When the package tray is relatively moved forward of the vehicle with respect to the shaft portion, the shaft portion is guided to the bearing portion.

  In this invention, it has the structure by which a package tray is supported so that rotation with respect to the vehicle body side is possible because a shaft part is attached to a bearing part. Then, in a state where the shaft portion is arranged in front of the vehicle from the front end portion of the package tray, that is, in a state where the shaft portion is not attached to the bearing portion, the package tray is moved relative to the shaft portion in front of the vehicle. In this case, the shaft portion is guided to the bearing portion by the guide portion. As a result, in a state where the shaft portion is arranged in front of the vehicle with respect to the front end portion of the package tray, when the package tray is pressed in front of the vehicle, it is possible to suppress the load on the shaft portion, and breakage of the shaft portion. Can be prevented in advance.

  The said structure WHEREIN: The said guide part shall be a notch part formed by notching the lower surface of the vehicle front-end part in the said package tray.

  With such a configuration, the guide portion can be provided with a simple configuration.

  In addition, the bearing portion includes an accommodation groove in which the shaft portion is accommodated, and a holding portion that is provided in the accommodation groove and holds the shaft portion, and the guide portion communicates with the accommodation groove. It has a first opening that is open in the front of the vehicle and can receive the shaft portion, and the first opening has a configuration in which the opening width decreases from the opening end toward the receiving groove. Can do.

  It has the 1st opening part from which an opening width becomes narrow as it goes to an accommodation groove from an opening end. Thereby, a shaft part can be more reliably guided to an accommodation slot by the 1st opening.

  The first opening has a first extending surface extending toward the housing groove, and a second extending that is disposed in front of the vehicle with respect to the first extending surface and extends toward the first extending surface. And an installation surface.

  With such a configuration, in a state where the shaft portion is arranged in front of the vehicle with respect to the front end portion of the package tray, the package tray is relatively moved forward of the vehicle with respect to the shaft portion, and the shaft portion is provided with the second extension. When contacting the surface, the shaft portion is guided to the first extending surface side along the second extending surface. Thereafter, the shaft portion is guided to the receiving groove along the first extending surface by contacting the first extending surface. Thereby, a shaft part can be guided to an accommodation slot more certainly.

  The package tray is provided with a second opening that extends from the bearing portion and opens toward the side away from the bearing portion, and the shaft portion is attached to the bearing portion. When a predetermined amount of load that does not exceed the elastic limit is received, the shaft portion is allowed to escape in a direction in which the predetermined amount of load is reduced, and the opening width of the second opening is the bearing As it goes from the portion toward the opening end of the second opening, it can be increased.

  According to such a configuration, in a state where the shaft portion is attached to the bearing portion, when the package tray receives an external force and a predetermined amount of load not exceeding the elastic limit is applied to the shaft portion, the predetermined amount of load is applied. The shaft part can escape in the direction of reduction. Thereby, the load concerning a shaft part can be reduced. Since the opening width of the second opening portion increases toward the opening end, the shaft portion can be surely released in a direction in which a predetermined amount of load is reduced.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where a package tray is not correctly attached to an axial part, the support structure of the package tray which can suppress the situation where a load is applied to an axial part can be provided.

  An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a support structure of the package tray 20 in the present embodiment. In FIG. 1, the package tray 20 is illustrated in a simplified manner. The package tray 20 is provided above the luggage compartment 30 in the vehicle. Further, a rear opening 15 is provided at the rear of the luggage compartment 30, and a back door 11 is rotatably attached to the vehicle body side as shown in FIG. 3 so that the rear opening 15 can be opened and closed. It has become.

  The package tray 20 is used for the purpose of shielding the cargo in the luggage compartment 30 from the outside by closing the gap between the seat back of the rear seat 12 and the back door 11. In the following description, “front” refers to the front of the vehicle based on the vehicle longitudinal direction, “rear” refers to the rear of the vehicle based on the vehicle longitudinal direction, and “width direction” refers to the vehicle width direction. And

  The package tray 20 is supported so as to be rotatable with respect to the vehicle body side with the front end portion as a rotation center. Thereby, as shown in FIG. 1, the package tray 20 can be rotated between a horizontal posture and a forward inclined posture. In FIG. 1, the package tray 20 in a horizontal posture is indicated by a solid line, and the package tray 20 in a forward tilt posture is indicated by a two-dot chain line, and a reference numeral 20A is attached thereto.

  As shown in FIG. 3, the rear portion of the package tray 20 is connected to the back door 11 side (for example, a side garnish of a back door trim (not shown)) via a suspender 13. The package tray 20 rotates in the vertical direction in conjunction with the operation. Specifically, when the back door 11 is opened, the package tray 20 is rotated from the horizontal posture to the forward tilted posture, and when the back door 11 is closed, the package tray 20 is rotated from the forward tilted posture to the horizontal posture.

  As shown in FIG. 2, hinge pins 32 (shaft portions) are respectively provided on the side walls 31 (vehicle body side) constituting both sides in the width direction of the luggage compartment 30. Both hinge pins 32 are formed integrally with a shelf 33 formed on the upper part of both side walls 31. Both hinge pins 32 have a round bar shape and project toward the cargo compartment side. In other words, the hinge pin 32 has a shape extending along the rotation axis L1 (see FIG. 2) with respect to the vehicle body side of the package tray 20. The hinge pins 32 are arranged coaxially with each other so that the protruding ends face each other.

  As shown in FIG. 1, the hinge pin 32 is disposed in the vicinity of the rear of the upper portion of the seat back of the rear seat 12. The hinge pin 32 is made of a synthetic resin material such as polypropylene together with the side wall 31. Further, the rear pillar 14 is located above the shelf 33.

  The shelf portion 33 is provided with a step portion 34 that supports the side edge in the width direction of the package tray 20 in a horizontal posture. The step portion 34 extends in the vehicle front-rear direction and is formed in a range from the rear of the hinge pin 32 to the rear end side of the package tray 20.

  As shown in FIG. 3, a pair of hinge collars 40 made of a synthetic resin material are attached to both sides of the front end portion of the package tray 20 in the width direction. Each hinge collar 40 is provided at a location corresponding to each hinge pin 32. Each hinge collar 40 is pivotally supported by each hinge pin 32, so that the package tray 20 can be rotated between a horizontal posture and a forward tilt posture.

  As shown in FIG. 10, the hinge collar 40 includes a base portion 40A having a substantially plate shape, a backing portion 40B, and a connecting portion 61 for connecting the base portion 40A and the backing portion 40B. The backing portion 40B has a substantially plate shape, and is integrally formed with the back surface (the surface on the vehicle interior side, the left surface in FIG. 10) of the base portion 40A via the connecting portion 61. The connecting portion 61 is set to a thickness that can be bent, and the backing portion 40B is rotatable with respect to the base portion 40A around the connecting portion 61 (hinge portion).

  A lock protrusion 62 having a substantially cylindrical shape protrudes from the back surface of the base portion 40A. A locking claw 62 </ b> A (broken line in FIG. 10) projects from the side surface of the locking projection 62. On the other hand, the backing portion 40B is formed with a lock hole 60A through which the lock projection 62 can be fitted. Further, an insertion hole 21 </ b> A is formed through the side portion 21 of the package tray 20.

  In the present embodiment, when the base portion 40A and the backing portion 40B are overlapped with the connecting portion 61 as the center of rotation in the state where the lock hole 60A and the insertion hole 21A are arranged coaxially, the lock protrusion 62 is formed. It is configured to be fitted (inserted) into both the insertion hole 21A and the lock hole 60A, and the locking claw 62A is hooked and locked to the hole edge of the lock hole 60A from the vehicle interior side (state of FIG. 10). .

  As a result, the side portion 21 of the package tray 20 is sandwiched between the base portion 40A and the backing portion 40B, and the hinge collar 40 is attached to the package tray 20. In addition, the attachment structure of the hinge collar 40 with respect to the package tray 20 is not limited to this structure, It can change suitably, For example, you may attach the hinge collar 40 by a screw stop etc. Further, the above-described lock protrusion 62 (shown by a broken line in FIG. 6), the lock hole 60A, and the insertion hole 21A are provided, for example, at locations corresponding to the vicinity of both ends of the hinge collar 40 in the vehicle front-rear direction.

  As shown in FIGS. 3 and 4, the base portion 40 </ b> A (hinge collar 40) is provided with a concave portion 41 having an indented shape in the width direction of the package tray 20 (the through direction in FIG. 3). . The recess 41 extends in a substantially U-shape opening downward in a side view shown in FIG. 3 and has a receiving groove 42 (bearing portion) in which the hinge pin 32 is received.

  Further, a positioning bead 49 (positioning protrusion) that protrudes toward the side wall 33A of the shelf 33 is provided above the recess 41 in the base portion 40A. The positioning bead 49 abuts against the side wall 33A of the shelf 33, thereby positioning the package tray 20 in the vehicle width direction, and also has a function of suppressing the backlash of the package tray 20 with respect to the hinge pin 32.

  The positioning bead 49 positions the package tray 20 in the vehicle width direction, thereby preventing the protruding end (tip) of the hinge pin 32 from coming into contact with the inner surface 41A of the recess 41. Thus, the package tray 20 can be smoothly rotated with respect to the hinge pin 32.

  In order to more effectively suppress the backlash of the package tray 20 with respect to the hinge pin 32, it is preferable to reduce the distance between the positioning bead 49 and the hinge pin 32. For this reason, the positioning bead 49 has a shape (substantially V-shaped) extending along the shape of the concave portion 41 (lower surface 41B) in a side view (see FIG. 3), and is arranged in a shape close to the hinge pin 32. .

  As shown in FIG. 4, in the base portion 40 </ b> A, a holding projection for holding the hinge pin 32 is located at a position facing the lower surface 41 </ b> B of the recess 41 (a surface extending downward in a substantially V shape). 47 is formed so as to protrude toward the side wall 33A. The housing groove 42 described above is mainly configured by the lower surface 41B of the recess 41, the inner surface 41A of the recess 41, and the upper surface 47A of the holding projection 47. In addition, the holding protrusion 47 is configured to be able to bend and deform with a connection portion with the back surface 41A of the recess 41 as a base end.

  As shown in FIG. 3, the hinge pin 32 is held by at least three points of a holding protrusion 47, a front-side bending protrusion 50 formed on the lower surface 41 </ b> B of the recess 41, and a rear-side bending protrusion 51. That is, the holding protrusion 47, the front side bending protrusion part 50, and the rear side bending protrusion part 51 are provided in the accommodation groove 42 and constitute a holding part (bearing part) that holds the hinge pin 32. Further, the holding projection 47, the front deflection projection 50, and the rear deflection projection 51 are attached to the hinge pin 32 so as to be rotatable.

  Here, “holding the hinge pin 32” means that the package tray 20 (hinge collar 40) is fixed to the hinge pin 32 so as to be rotatable. Further, in the following description, the state in which the hinge pin 32 is held by the holding protrusion 47, the front side bending protrusion part 50, and the rear side bending protrusion part 51 is referred to as a normal attachment state of the hinge pin 32.

  As shown in FIG. 3, the front-side deflection protrusion 50 is provided obliquely in front of the holding protrusion 47 (upper left side in FIG. 3). The front-side deflection protrusion 50 is formed in a cantilevered manner with respect to the lower surface 41 </ b> B of the recess 41. Thereby, the front side bending protrusion part 50 can be elastically bent and deformed in a direction in which the center part (free end) is separated from the holding protrusion part 47. Further, the central portion of the front-side bending protrusion 50 protrudes toward the holding protrusion 47 and is disposed on the moving path of the hinge pin 32 in the accommodation groove 42.

  As shown in FIG. 3, the rearward deflection protrusion 51 is provided obliquely behind the holding protrusion 47 (upper right side in FIG. 3). The rear-side bending protrusion 51 is formed so as to be both-side supported with respect to the lower surface 41 </ b> B of the recess 41. As a result, the rear-side bending projection 51 can be elastically bent and deformed in a direction in which the central portion (free end) is separated from the holding projection 47. The central portion of the rear-side bending protrusion 51 protrudes toward the holding protrusion 47 and is disposed on the moving path of the hinge pin 32 in the accommodation groove 42.

  Further, as shown in FIGS. 4 and 6, an elongate contact protrusion 47 </ b> B is provided on the upper surface 47 </ b> A of the holding protrusion 47. The hinge pin 32 in the normal attachment state does not contact the holding projection 47 directly, but indirectly contacts via the contact projection 47B. Further, an opposing protrusion 48B is provided at a position facing the contact protrusion 47B in the vertical direction (between the front-side bending protrusion 50 and the rear-side bending protrusion 51). As a result, when the hinge pin 32 enters deeply between the front deflection projection 50 and the rear deflection projection 51, the hinge pin 32 comes into contact with the opposing projection 48B.

  In addition, the package tray 20 of the present embodiment has a first opening 43 provided in front of the housing groove 42 (bearing portion) so as to communicate with the housing groove 42, and a housing groove 42 so as to communicate with the housing groove 42. And a second opening 45 provided at the rear of the.

  The first opening 43 (guide portion) is for guiding the hinge pin 32 to the receiving groove 42, and is configured to be open to the front of the vehicle and receive the hinge pin 32 from the front. The first opening 43 is a notch formed by notching the lower surface of the front end of the package tray 20 (including the hinge collar 40). Further, the first opening 43 has a configuration in which the opening width B1 decreases from the opening end (front end) toward the accommodation groove 42 (a configuration in which the opening width increases toward the opening end).

  3 and 4, the first opening 43 includes a front end 43A (second extending surface) on the lower surface of the package tray 20, a front end 43B on the lower surface of the base portion 40A, and a front side of the holding protrusion 47. The side surface 47D (first extending surface) is mainly configured. It should be noted that the front end portion 43A on the lower surface of the package tray 20 is formed to be continuous with the front end portion 43B on the lower surface of the base portion 40A.

  As shown in FIG. 5, the height of the front end portion 43 </ b> A in the horizontally oriented package tray 20 is the same as that of the hinge pin 32. As a result, when the package tray 20 in the horizontal posture is arranged behind the hinge pin 32 (see FIG. 5), when the package tray 20 in the horizontal posture slides and moves forward in the vehicle, the hinge pin 32 moves to the front end portion 43A. It is the structure which contacts.

  Further, the front end portion 43A on the lower surface of the package tray 20 is an inclined surface that slightly inclines downward as it goes rearward. The inclination angle of the front end portion 43A on the lower surface of the package tray 20 is an imaginary extending surface extending along the extending direction of the front end portion 43A (indicated by a two-dot chain line in FIG. 6 and denoted by reference numeral 44). Is set at an angle that intersects (abuts) the front side surface 47D of the holding projection 47. That is, the front end portion 43A on the lower surface of the package tray 20 is disposed in front of the side surface 47D of the holding projection 47 and is an extended surface extending toward the side surface 47D.

  On the other hand, the front side surface 47 </ b> D of the holding projection 47 is a curved surface (inclined surface) that rises and inclines toward the accommodation groove 42. That is, the front side surface 47 </ b> D of the holding projection 47 is an extended surface extending toward the accommodation groove 42.

  As shown in FIG. 3, the second opening 45 is opened obliquely downward (side away from the housing groove 42). Further, the opening width B <b> 2 (see FIG. 6) of the second opening 45 increases from the accommodation groove 42 toward the opening end of the second opening 45.

  A pair of check pieces 52 are provided at the opening end of the second opening 45. Both check pieces 52 are provided on both sides of the second opening 45 in the opening width direction of the second opening 45 (substantially horizontal direction in FIG. 3). The surface on the second opening 45 side at the tip of both check pieces 52 is an inclined surface that is inclined in a direction away from the second opening 45 toward the tip.

  Thereby, when the hinge pin 32 moves to the outside of the package tray 20 through the second opening 45, both the check pieces 52 pressed by the hinge pin 32 are easily bent and deformed, and the hinge pin 32 is in the second position. The opening 45 can be moved to the outside of the package tray 20.

  On the other hand, when the hinge pin 32 enters the second opening 45 from the outside of the package tray 20, the check piece 52 is not easily bent and deformed, and the movement of the hinge pin 32 is restricted. ing. In other words, the check pieces 52 are for preventing the hinge pin 32 from returning to the second opening 45 again after coming out of the package tray 20 from the second opening 45.

  Next, the operation and effect of this embodiment will be described. First, the operation when the vehicle user closes the back door 11 in a state where the package tray 20 is not attached to the hinge pin 32 and the hinge pin 32 is arranged in front of the package tray 20 (the state shown in FIG. 5). Explain.

  Note that the package tray 20 is in the state shown in FIG. 5, for example, when the vehicle user removes the package tray 20 from the hinge pin 32 and places the package tray 20 on the stepped portion 34, but the hinge pin 32 If you forgot to install it. In FIG. 5, the package tray 20 is not connected to the back door 11 side by the suspender 13, and a state in which the package tray 20 is placed in the horizontal position by being placed on the stepped portion 34 is illustrated. .

  As shown in FIG. 3, when the package tray 20 is attached to the hinge pins 32 (normally attached state), the back door 11 in the closed state and the package tray 20 do not interfere with each other. On the other hand, in the state where the hinge pin 32 is arranged in front of the package tray 20 (the state shown in FIG. 5), the package tray 20 is arranged behind the normal mounting position, and therefore the closed back door 11 is closed. And the package tray 20 may interfere with each other.

  When the back door 11 and the package tray 20 interfere with each other, the package tray 20 is pressed from behind by the back door 11. Accordingly, when the package tray 20 moves forward along the stepped portion 34, the hinge pin 32 enters the first opening 43 from the front. Specifically, as shown in FIG. 6, the hinge pin 32 contacts the front end portion 43 </ b> A on the lower surface of the package tray 20. The hinge pin 32 is moved relative to the package tray 20 along the front end 43A. That is, the hinge pin 32 is guided toward the front side surface 47D of the holding projection 47 by the front end portion 43A.

  Next, after the hinge pin 32 guided toward the side surface 47D abuts on the side surface 47D of the holding projection 47, the hinge pin 32 is moved relative to the package tray 20 along the side surface 47D. That is, the hinge pin 32 is guided toward the accommodation groove 42 by the side surface 47D. In FIG. 6, the hinge pin 32 (reference numeral 32A) in contact with the side surface 47D is indicated by a two-dot chain line.

  As described above, the first opening 43 (including the front end portion 43A and the side surface 47D) is arranged such that the package tray 20 is in front of the vehicle with respect to the hinge pin 32 in a state where the hinge pin 32 is disposed in front of the vehicle. The hinge pin 32 is guided to the receiving groove 42 when it is relatively moved.

  Then, when the hinge pin 32 guided to the accommodation groove 42 enters the accommodation groove 42, the hinge pin 32 gets over the front deflection protrusion 50 while bending the front deflection protrusion 50. Then, as shown in FIG. 3, the hinge pin 32 is supported at at least three points of the holding projection 47, the front side deflection projection portion 50, and the rear side deflection projection portion 51. Thereby, the hinge pin 32 is accommodated in the accommodation groove | channel 42, and is hold | maintained in a regular attachment state.

  When removing the package tray 20 from the hinge pin 32, the package tray 20 is pulled backward from the state shown in FIG. As a result, the hinge pin 32 bends and deforms the front-side bending protrusion 50, so that the hinge pin 32 passes through the first opening 43 from the accommodation groove 42 and is displaced to the outside of the package tray 20.

  FIG. 7 is a diagram illustrating an operation when the back door 11 is closed in a state where the hinge pin 32 is arranged in front of the package tray 20 connected to the back door 11 by the suspender 13. As shown in FIG. 7, in a state where the package tray 20 is connected to the back door 11 by the suspender 13, the package tray 20 rotates from the forward tilted posture to the horizontal posture as the back door 11 is closed.

  In this turning process, when the package tray 20 is pressed forward by the back door 11, the hinge pin 32 comes into contact with the front end portion 43A on the lower surface of the package tray 20, as shown in FIG. Thereafter, the same operation as when the package tray 20 is not connected to the back door 11 by the suspender 13 (described above) is shown, and the hinge pin 32 is guided to the receiving groove 42. That is, in the present embodiment, the hinge pin 32 can be guided to the receiving groove 42 by the first opening 43 regardless of whether or not the package tray 20 is connected by the suspender 13.

  Next, the operation when the back door 11 is closed in a state where the package tray 20 is in the forward tilted state (state shown in FIG. 8) will be described. The package tray 20 may be inclined forward as shown in FIG. 8, for example, when a load P having a height higher than the height of the package tray 20 in a horizontal posture is mounted in the luggage compartment 30. . In this case, since the rear portion of the package tray 20 is supported by the luggage P, the package tray 20 does not rotate to the horizontal posture.

  If the back door 11 is to be closed in this state, the window portion 11A of the back door 11 may come into contact with the rear end portion of the package tray 20 as shown in FIG. As a result, the package tray 20 is pushed forward by the window portion 11 </ b> A while keeping the forward inclined posture.

  At this time, the hinge pin 32 is pressed by the holding projection 47 and the rear side deflection projection 51 of the hinge collar 40 from the rear and receives a load. At this time, the holding protrusion 47 and the rear-side bending protrusion 51 are bent and deformed in a direction away from each other by a reaction from the hinge pin 32. When the load received by the hinge pin 32 reaches a predetermined amount (an amount that does not exceed the elastic limit of the hinge pin 32), the facing interval between the holding projection 47 and the rearward deflection projection 51 becomes wider than the diameter of the hinge pin 32. As a result, the hinge pin 32 passes between the holding projection 47 and the rear flexure projection 51, and relatively moves from the accommodation groove 42 to the second opening 45 as shown in FIG. In FIG. 9, the hinge pin 32 in the normally attached state is illustrated by a two-dot chain line.

  That is, the second opening 45 is configured to release the hinge pin 32 in a direction in which the load applied to the hinge pin 32 is reduced when the hinge pin 32 receives a predetermined amount of load that does not exceed the elastic limit. Note that the “predetermined amount” referred to here depends on the ease of bending of the holding projection 47 and the rear deflection projection 51. In other words, the holding protrusion 47 and the rear-side bending protrusion 51 are configured to bend and deform before the load received by the hinge pin 32 exceeds the elastic limit.

  Note that the distance between the front end portion of the package tray 20 and the seat back of the rear seat 12 is such that the package tray 20 is returned from the forward inclined posture to the horizontal posture even when the hinge pin 32 is accommodated in the second opening 45. It is set with a length that can be. For this reason, even if the hinge pin 32 is accommodated in the second opening 45, the package tray 20 can be rotated without interfering with the rear seat 12, and a load may be applied to the hinge pin 32. There is no.

  Further, when the vehicle is started in a state where the hinge pin 32 is accommodated in the second opening 45, the hinge pin 32 is not stably held with respect to the hinge collar 40. The tray 20 also vibrates. Thereby, since abnormal noise is generated when the package tray 20 comes into contact with the peripheral components, the vehicle user can detect that the hinge pin 32 is not in the normal attachment state. In this case, the hinge pin 32 may be taken out through the second opening 45, and then the hinge pin 32 may be attached to the receiving groove 42 through the first opening 43.

  As described above, in the present embodiment, the package pin 20 is supported so as to be rotatable with respect to the vehicle body side by attaching the hinge pin 32 to the accommodation groove 42. In a state where the hinge pin 32 is arranged in front of the vehicle from the front end portion of the package tray 20, that is, in a state where the hinge pin 32 is not attached to the receiving groove 42, the package tray 20 is in front of the vehicle with respect to the hinge pin 32. When the relative movement is performed, the hinge pin 32 is guided to the accommodation groove 42 by the first opening 43.

  As a result, in a state where the hinge pin 32 is arranged in front of the vehicle from the front end portion of the package tray 20, it is possible to suppress a situation in which a load is applied to the hinge pin 32 when the package tray 20 is pressed forward of the vehicle. Can be prevented beforehand. In addition, since the hinge pin 32 is guided to the receiving groove 42, the attachment of the package tray 20 to the hinge pin 32 is completed, so that it is not necessary to attach the package tray 20 again.

  Further, by providing the first opening 43 (guide portion), when the package tray 20 is attached to the hinge pin 32, the package tray 20 is slid forward along the step portion 34 from the state of FIG. The package tray 20 can be easily attached, and workability related to the attachment is improved.

  In the above configuration, the first opening 43 is a notch formed by notching the lower surface of the front end of the vehicle in the package tray 20.

  If it is such a structure, the 1st opening part 43 (guide part) can be provided with a simple structure.

  Further, the bearing portion is provided in the accommodation groove 42 in which the hinge pin 32 is accommodated and the accommodation groove 42 and holds the hinge pin 32 (holding projection 47, front deflection projection 50, rear deflection projection 51). The guide portion is open to the front of the vehicle so as to communicate with the receiving groove 42, and has a first opening 43 that can receive the hinge pin 32. The first opening 43 extends from the opening end to the receiving groove. The opening width becomes narrower toward 42.

  By having the first opening 43 whose opening width becomes narrower from the opening end toward the accommodation groove 42, the first opening 43 can easily receive the hinge pin 32, and the first opening 43 makes the hinge pin 32 more reliable. It is possible to guide to the receiving groove 42.

  The first opening 43 is disposed on the front side of the vehicle with respect to the first extending surface (side surface 47D of the holding projection 47) extending toward the housing groove 42 and the side surface 47D, and extends toward the side surface 47D. Extending surface (front end portion 43A on the lower surface of the package tray 20).

  With such a configuration, the package tray 20 is moved relative to the hinge pin 32 relative to the front of the vehicle in a state where the hinge pin 32 is disposed in front of the front end of the package tray 20, and the hinge pin 32 is moved to the package tray. When contacting the front end 43A on the lower surface of the hinge 20, the hinge pin 32 is guided along the front end 43A to the side surface 47D of the holding projection 47. Thereafter, the hinge pin 32 is guided to the receiving groove 42 along the side surface 47D by contacting the side surface 47D. Thereby, the hinge pin 32 can be more reliably guided with respect to the accommodation groove 42.

  Further, the package tray 20 is provided with a second opening 45 that extends from the accommodation groove 42 and opens toward the side away from the accommodation groove 42, and the hinge pin 32 is attached to the accommodation groove 42 in the second opening 45. When a predetermined amount of load that does not exceed the elastic limit is received, the hinge pin 32 is allowed to escape in a direction in which the predetermined amount of load is reduced, and the opening width B2 of the second opening 45 is the receiving groove. It becomes larger as it goes from 42 to the opening end of the second opening 45.

  According to such a configuration, in a state where the hinge pin 32 is attached to the receiving groove 42, when the package tray 20 receives an external force and a predetermined amount of load not exceeding the elastic limit is applied to the hinge pin 32, the predetermined amount of The hinge pin 32 can be released in a direction that reduces the load. Thereby, the load concerning the hinge pin 32 can be reduced. And since the opening width B2 becomes large as the 2nd opening part 45 goes to the opening end, it can escape reliably the hinge pin 32 by the direction where a predetermined amount of load reduces.
