Description

  The present invention relates to a side lock device that is attached to a movable member movable with respect to a fixed member and locks the movable member to the fixed member.

  A side lock device is disposed in a grab box for a vehicle. The side lock device locks the lid (movable member) of the grab box to the box body (fixed member).

  A general side lock device has a swingable operation knob and two slidable flanges, and is attached to a lid (see, for example, Patent Documents 1 to 3). The two flanges are urged in a direction protruding toward the box body. The front end of each collar engages with an engagement hole formed in the left and right side walls of the box body. For this reason, the lid is locked to the box body.

  When the operation knob is swung, the two hooks slide in a direction away from the box body, and the engagement between the tip of each hook and the box body is released. For this reason, the lock is released and the lid can be moved relative to the box body.

  By the way, conventionally, it has been considered that it is preferable to operate each of the two collars independently as a countermeasure against a lock failure. This is because the lid can be locked to the box body as long as the other collar part operates even if one collar part does not work. However, in order to operate each of the two hooks independently, many parts are required for transmitting the swing of the operation knob to each hook. For this reason, there is a problem that it is difficult to reduce the manufacturing cost of the side lock device.

  Moreover, when operating two hook parts independently, only one hook part may engage with an engagement hole by the position shift | offset | difference with respect to a box main body. In this case, since the lid is locked to the box body in a misaligned state, a large force is applied to the side lock device or the lid, and the side lock device or the lid may be deformed. Therefore, in recent years, there has been a demand for a side lock device in which the two buttocks operate in synchronization.

  By the way, the operation knob in the grab box may be provided near the driver's seat in order to improve operability from the driver's seat. In this case, the distance between the operation knob and the side wall of the box body is different on the left and right, and the lengths of the two hooks are different. For right-hand drive cars and left-hand drive cars, the position of the grab box with respect to the driver's seat is reversed left and right.Therefore, the side lock device for right-hand drive vehicles and the side lock device for left-hand drive vehicles have a horizontally reversed shape. There is a need to.

Further, a key cylinder may be provided in the side lock device in order to lock the lid with respect to the box body. When the side lock device is reversed left and right between the right-hand drive vehicle and the left-hand drive vehicle, the locking direction and the unlocking direction of the key cylinder are reversed between the right-hand drive vehicle and the left-hand drive vehicle. The locking direction of a general key cylinder is clockwise, and the unlocking direction is counterclockwise. For this reason, when the locking direction and the unlocking direction are reversed, it becomes difficult for the user to recognize the locking direction and the unlocking direction of the key cylinder. For this reason, in this case, there is a problem that it is difficult to obtain a side lock device that is excellent in usability. Therefore, a side lock device for a right-hand drive vehicle cannot be used as a side lock device for a left-hand drive vehicle. This also has a problem that it is difficult to reduce the manufacturing cost of the side lock device.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a side lock device in which two collars operate in synchronization to reduce manufacturing costs.

The side lock device 1 of the present invention that solves the above problems includes an operation knob main body 20 and a key cylinder 21 that has a pressing portion 24 and is attached to the operation knob main body 20 and rotates between a locked position and an unlocked position. An operation knob 2 that swings between a pressing start position and a pressing end position, a knob urging means 3 that is attached to the operation knob 2 and urges the operation knob 2 to the pressing start position, and a rotating shaft 40. And two pressure receiving portions 43 , 44 and two input portions 41, 42 that are separated from the rotation shaft 40, and rotate between a pressure receiving start position and a pressure receiving end position around the rotation shaft 40. Link member 4 to be connected, link urging means 5 attached to the link member 4 and urging the link member 4 to the pressure receiving start position, a first connection portion 62 connected to one input portion 41, and a first 1st engagement arrange | positioned in the left side rather than the connection part 62 When the link member 4 rotates from the pressure receiving start position toward the pressure receiving end position, it slides to the right, and when the link member 4 rotates from the pressure receiving end position toward the pressure receiving start position, it moves to the left. It has a first collar portion 6 that slides, a second connection portion 72 that is connected to the other input portion 42, and a second engagement portion 71 that is disposed to the right of the second connection portion 72. When the link member 4 rotates from the pressure receiving start position toward the pressure receiving end position, it slides to the left, and when the link member 4 rotates from the pressure receiving end position to the pressure receiving start position, the second collar portion slides to the right. 7, and the two input parts 41 and 42 are separated from each other in the circumferential direction of the circle around the rotation shaft 40, and the one input part 41 (42) and the first connection part 62 are universal joints. The second input 42 (41) and the second connection The part 72 engages with a universal joint, and the two pressure receiving parts 43 and 44 have a line-symmetric shape with respect to a straight line passing through the two input parts 41 and 42, and the operation knob 2 is pressed from the pressing start position. When the key cylinder 21 is located at the unlocking position, the movement region of the pressing portion 24 when swinging to the position is formed at a position that passes through at least a part of the pressure receiving portion 43 (44) , and the key cylinder 21 is locked. when disposed in position is formed at a position avoiding the pressure receiving portion 43 (44), the operating knob 2 when disposed in the key cylinder 21 unlocking position swinging toward the pressing end position from the pressing start position When moved, the pressure receiving portion 43 (44) is pressed by the pressing portion 24, and the link member 4 is rotated from the pressure receiving start position toward the pressure receiving end position.
The following elements in the side lock device of the present invention are referred to as (1) and (2).
(1) The two input portions 41 and 42 are separated from each other in the circumferential direction of a circle centered on the rotation shaft 40.
(2) The one input portion 41 of the link member 4 and the first connection portion 62 of the first flange 6 are engaged in a universal joint shape, and the other input portion 42 of the link member 4 is engaged. And the 2nd connection part 72 of the said 2nd collar part 7 is engaging in the universal joint shape.

The side lock device of the present invention preferably includes the following (3) .

  (3) A recess groove 45 having a concave shape is formed in a region between the pressure receiving portion 43 and the rotating shaft 40 in the link member 4.

  According to the side lock device of the present invention, the two hook parts (the first hook part and the second hook part) slide in opposite directions by rotating one link member in response to the swing of the operation knob. . For this reason, according to the side lock device of the present invention, it is possible to synchronize the operations of the two flanges.

  In addition, according to the side lock device of the present invention, since the operations of the two flange portions are synchronized by one link member, the number of parts can be greatly reduced.

  By the way, as described above, the operation knob in the grab box may be arranged at a position close to the driver's seat. For example, an operation knob in a grab box of a right-hand drive vehicle is disposed at the right end of the grab box, and an operation knob in a grab box of a left-hand drive vehicle is disposed at the left end of the grab box. In these cases, there may be a case where a sufficient space for arranging various members cannot be secured on the right or left side of the operation knob (particularly the key cylinder).

  On the other hand, according to the side lock device of the present invention, if the link member is arranged so that the relative position in the left-right direction between the rotation shaft and the pressure receiving portion is reversed, the link member is rotated in the reverse direction. The left and right relative positions of the key cylinder and the link member can be reversed. In this case, if the first hook part and the second hook part and the two input parts are connected in an appropriate combination, the first hook part is slid rightward regardless of the rotation direction of the link member, The two buttocks can be slid to the left. Therefore, in the side lock device of the present invention, the portions other than the first and second collars can be shared by the right-hand drive vehicle and the left-hand drive vehicle. Therefore, according to the side lock device of the present invention, the manufacturing cost of the side lock device can be reduced.

  Further, the two pressure receiving portions of the link member in the side lock device of the present invention have a line-symmetric shape. The pressure receiving portion is a portion that is pressed by the pressing portion of the operation knob when the operation knob swings and receives a force due to the swing of the operation knob. In the side lock device of the present invention, the two pressure receiving portions have a symmetrical shape with respect to a straight line that connects the two input portions. For this reason, in the right-hand drive vehicle, one pressure receiving portion receives a force due to the swing of the operation knob, and in the left-hand drive vehicle, the other pressure receiving portion receives a force due to the swing of the operation knob. Therefore, in the side lock device of the present invention, the portions other than the first and second collars can be shared by the right-hand drive vehicle and the left-hand drive vehicle. Therefore, according to the side lock device of the present invention, the manufacturing cost of the side lock device can be reduced.

  Further, according to the side lock device of the present invention, the anti-theft function can be imparted to the side lock device while reducing the manufacturing cost of the side lock device. This is due to the following reason.

  Normally, the key cylinder in the side lock device engages with the operation knob main body when it is disposed at the locking position, so that the operation knob cannot be swung. A general key cylinder is made of metal and is a highly rigid member. On the other hand, an operation knob body in a general side lock device is made of resin and has lower rigidity than a key cylinder. Therefore, even if the key cylinder is placed in the locked position and the key cylinder is engaged with the operation knob body, if an excessive external force is applied to the operation knob, the operation knob body will be deformed or damaged, and The engagement with the knob body may be released. If the operation knob is swung in a state where the engagement between the key cylinder and the operation knob main body is released, the engagement between the two flange portions and the fixed member is released, and the movable member moves relative to the fixed member. .

  If the operation knob body is made of metal, it is considered that the engagement between the key cylinder and the operation knob body when the key cylinder is placed in the locked position can be maintained with high reliability. The manufacturing cost of the device increases.

  In the side lock device of the present invention, when the key cylinder is disposed at the locking position, the movement region of the pressing portion when the operation knob swings from the pressing start position to the pressing end position (hereinafter simply referred to as the movement region of the pressing portion). Is formed at a position avoiding the pressure receiving portion. Therefore, if the key cylinder is disposed at the locking position, the pressing portion and the pressure receiving portion do not come into contact with each other even when the operation knob is swung. Accordingly, in this case, the two flanges are maintained in a state of being engaged with the fixed member, and the movable member is maintained in a state of being locked to the fixed member. In other words, according to the side lock device of the present invention, when the key cylinder is arranged at the locking position, the operation knob body is swung (or an excessive external force is applied to the operation knob body to deform or break it). In addition, the movable member can be maintained in a locked state with the fixed member. Therefore, according to the side lock device of the present invention, the operation knob body can be made of resin, and the manufacturing cost can be reduced. Further, since the lock is not released when the key cylinder is disposed at the locking position, theft can be prevented.

  The side lock device of the present invention is preferably used as a side lock device disposed in a grab box for a vehicle.

  Hereinafter, the side lock device of the present invention will be described by way of example.

One end of the link urging means 5 is fixed to the link member 4, and the other end of the link urging means 5 is fixed to the lid 90. The link biasing means 5 biases the link member 4 to the pressure receiving start position shown in FIG.

  The 1st collar part 6 makes the substantially bowl shape extended to right and left. The left end portion of the first flange portion 6 is tapered and constitutes a first engagement portion 61. A first connecting portion 62 that is concave and opens forward is formed at the right end of the first flange portion 6. As shown in FIG. 5, the internal space of the first connection portion 62 has a slightly larger diameter than the opening end portion of the first connection portion 62. The first input unit 41 is inserted into the first connection unit 62. As described above, the protruding end portion of the first input portion 41 has a curved shape that bulges backward. For this reason, the 1st input part 41 and the 1st connection part 62 engage in a universal joint shape. The first engagement portion 61 is inserted through a first retainer 91 that is fixed to the left end portion of the lid 90. The first flange 6 is disposed on the rear side of the link member 4.

  The 2nd collar part 7 makes the collar shape extended in substantially Z shape. The length of the second hook part 7 in the left-right direction is longer than the length of the first hook part 6 in the left-right direction. The right end portion of the second collar portion 7 has a tapered shape and constitutes a second engagement portion 71. A second connecting portion 72 is formed at the left end portion of the second collar portion 7 so as to form a concave shape in the rear and open. As shown in FIG. 5, the internal space of the second connection portion 72 is slightly larger in diameter than the opening end portion of the second connection portion 72. The second input unit 42 is inserted into the second connection unit 72. The protruding end portion of the second input portion 42 has a curved surface shape that bulges forward. For this reason, the 2nd input part 42 and the 2nd connection part 72 engage in a universal joint shape. The second engaging portion 71 is inserted through a second retainer 92 that is fixed to the right end portion of the lid 90. The first flange 6 is disposed on the front side of the link member 4 and on the rear side of the operation knob 2.

  Hereinafter, the operation of the side lock device 1 of the first embodiment will be described.

  The link member 4 is biased to the pressure receiving start position by the link biasing means 5. The operation knob 2 is urged to the pressing start position by the knob urging means 3. Therefore, when the user is not touching the operation knob 2, as shown in FIGS. 3 and 7, the first engagement portion 61 of the first collar portion 6 protrudes greatly to the left, and the second collar portion 7 2 The engaging part 71 protrudes greatly to the right. When the lid 90 is disposed at the closed position, the first engagement hole 93 formed in the box body is disposed on the left side of the first retainer 91, and the second engagement hole 94 formed in the box body is formed. It is arranged on the right side of the second retainer 92. Accordingly, at this time, the first engagement portion 61 enters the first engagement hole 93, and the second engagement portion 71 enters the second engagement hole 94. Accordingly, at this time, the side lock device 1 can lock the lid 90 in the closed position.

  At this time, if the key cylinder 21 is disposed at the unlocked position, the pressing portion 24 is disposed above the first pressure receiving portion 43 as shown in FIGS. Therefore, the movement region of the pressing portion 24 is formed at a position passing through the first pressure receiving portion 43 of the link member 4. Therefore, at this time, if the user pulls up the operation knob body 20 and swings the operation knob 2 from the pressing start position toward the pressing end position, the pressing portion 24 moves downward as shown in FIG. The pressure receiving part 43 is pressed. Then, as shown by the arrow in FIG. 3, the link member 4 rotates counterclockwise about the rotation shaft 40 and is disposed at the pressure receiving end position shown in FIG. At this time, the moving region of the pressing portion 24 is formed at a position avoiding the second pressure receiving portion 44. Therefore, the second pressure receiving portion 44 does not contact the pressing portion 24 and is not pressed by the pressing portion 24.

  When the link member 4 rotates from the pressure receiving start position to the pressure receiving end position, the first input unit 41 moves to the right. For this reason, the 1st connection part 62 connected to the 1st input part 41 moves to the right, and the 1st collar part 6 slides to the right. Therefore, the engagement between the first engagement portion 61 of the first flange portion 6 and the first engagement hole 93 of the box body is released. At the same time, the second input unit 42 moves to the left. For this reason, the 2nd connection part 72 connected to the 2nd input part 42 moves to the left, and the 2nd collar part 7 slides to the left. Therefore, the engagement between the second engagement portion 71 of the second flange portion 7 and the second engagement hole 94 of the box body is released. Therefore, the lid 90 can move toward the open position.

  Further, when the user releases the operation knob 2 with the lid 90 placed at the closed position, the operation knob 2 swings from the pressing end position to the pressing start position by the urging force of the knob urging means 3. The link member 4 is rotated clockwise in FIG. 3 by the biasing force of the link biasing means 5. That is, the link member 4 rotates from the pressure receiving end position toward the pressure receiving start position. For this reason, the 1st input part 41 of link member 4 moves to the left. Therefore, the first connection part 62 connected to the first input part 41 also moves to the left, and the first collar part 6 slides to the left. Accordingly, the first engagement portion 61 of the first flange portion 6 engages with the first engagement hole 93 of the box body. At the same time, the second input unit 42 moves to the right. Therefore, the second connection part 72 connected to the second input part 42 moves to the right, and the second collar part 7 slides to the right. Accordingly, the second engagement portion 71 of the second collar portion 7 engages with the second engagement hole 94 of the box body. Therefore, the lid 90 is locked in the closed position.

  When the lid 90 is locked in the closed position, when the key is inserted into the key hole of the key cylinder 21 and the key cylinder 21 is rotated to the locked position, the key cylinder 21 is pressed as shown in FIGS. The part 24 moves to the left outer side of the link member 4. Accordingly, the moving region of the pressing portion 24 is formed at a position avoiding the first pressure receiving portion 43 and the second pressure receiving portion 44 of the link member 4. Therefore, even if the operation knob 2 is swung from the pressing start position to the pressing end position at this time, the pressing portion 24 and the first pressure receiving portion 43 do not contact each other. The pressing part 24 and the second pressure receiving part 44 do not contact either. In other words, at this time, the operation knob 2 is swung, and the swing of the operation knob 2 is not transmitted to the link member 4. Therefore, the first engagement portion 61 of the first flange portion 6 is maintained in a state of being engaged with the first engagement hole 93 of the fixing member, and the second engagement portion 71 of the second flange portion 7 is maintained in the first position of the fixing member. 2 The state engaged with the engagement hole 94 is maintained.

  Therefore, even if a large external force is applied to the operation knob 2 at this time, the lid 90 is maintained in a locked state on the box body.

  The side lock device 1 of the first embodiment greatly reduces the number of parts of the side lock device 1 in order to transmit the swing of the operation knob 2 to the first flange portion 6 and the second flange portion 7 by one link member 4. it can. Moreover, since the operation of the first collar part 6 and the operation of the second collar part 7 are synchronized by the link member 4, only one of the first collar part 6 and the second collar part 7 is engaged with the box body. Never do. For this reason, according to the side lock device 1 of the first embodiment, it is difficult for a large external force to act on the side lock device 1 and the lid 90, and deformation of the side lock device 1 and the lid 90 can be suppressed.

  Further, when the key cylinder 21 is disposed at the locking position, the operation knob 2 is swung, and the swing of the operation knob 2 is not transmitted to the link member 4. For this reason, even if resin is selected as the material of the operation knob 2, the lock is not released when the key cylinder 21 is disposed at the locking position. Therefore, according to the side lock device 1 of the first embodiment, the anti-theft function can be imparted to the side lock device 1 while reducing the manufacturing cost of the side lock device 1.

Is. In addition, the 2nd pressure receiving part 44 in the link member 4 of Example 2 is corresponded to the pressure receiving part in this invention.

  In the side lock device 1 of the second embodiment, the link member 4 is pivotally supported on the rear side and the left side of the key cylinder 21.

  The 1st collar part 6 in the side lock apparatus 1 of Example 2 makes the collar shape extended in substantially Z shape. The left end portion of the first flange portion 6 is tapered and constitutes a first engagement portion 61. A first connecting portion 62 is formed at the right end of the first flange 6 and has a concave shape and opens rearward. The second input unit 42 is inserted into the first connection unit 62. The second input portion 42 and the first connection portion 62 are engaged in a universal joint shape.

  The second collar portion 7 has a bowl shape. The length of the second hook part 7 in the left-right direction is shorter than the length of the first hook part 6 in the left-right direction.

A second connection portion 72 having a concave shape and opening forward is formed at the left end portion of the second flange portion 7. The first input unit 41 is inserted into the second connection unit 72. The first input part 41 and the second connection part 72 are engaged in a universal joint shape.

  Hereinafter, the operation of the side lock device 1 of the second embodiment will be described.

  When the user is not touching the operation knob, as shown in FIGS. 9 and 12, the first engagement portion 61 of the first flange portion 6 protrudes greatly to the left, and the second engagement portion of the second flange portion 7. 71 protrudes greatly to the right. Therefore, at this time, the side lock device 1 can lock the lid in the closed position.

  At this time, if the key cylinder 21 is disposed at the unlocking position, the pressing portion 24 is disposed above the second pressure receiving portion 44 as shown in FIGS. Accordingly, the moving region of the pressing portion 24 is formed at a position passing through the second pressure receiving portion 44 of the link member 4. Therefore, at this time, if the user swings the operation knob 2 from the pressing start position toward the pressing end position, the pressing portion 24 moves downward to press the second pressure receiving portion 44. Then, as shown by the arrow in FIG. 9, the link member 4 rotates clockwise about the rotation shaft 40 and is disposed at the pressure receiving end position shown in FIG. 11. At this time, since the first input unit 41 moves to the left and the second input unit 42 moves to the right, the first collar 6 slides to the right and the second collar 7 slides to the left. To do. Therefore, the engagement between the first engagement portion 61 of the first flange portion 6 and the first engagement hole 93 of the box body is released, and the second engagement portion 71 of the second flange portion 7 and the box body The engagement with the second engagement hole 94 is released. Therefore, the lid can move toward the open position.

  When the user releases the operation knob with the lid placed at the closed position, the operation knob swings to the pressing start position, and the link member 4 rotates counterclockwise in FIG. 9 and rotates to the pressure receiving start position. Move. For this reason, the 1st collar part 6 slides to the left, and the 2nd collar part 7 slides to the right. Accordingly, the first engagement portion 61 of the first flange portion 6 is engaged with the first engagement hole 93 of the box body, and the second engagement portion 71 of the second flange portion 7 is the second engagement portion of the box body. Engages with the joint hole 94. Thus, the lid is locked in the closed position.

  When the lid is locked in the closed position, when a key is inserted into the key hole of the key cylinder 21 and the key cylinder 21 is rotated to the locking position (counterclockwise direction in FIG. 9), it is shown in FIGS. As described above, the pressing portion 24 of the key cylinder 21 moves to the right inner side of the link member 4 and is disposed inside the escape groove portion 45. Accordingly, the moving region of the pressing portion 24 is formed at a position avoiding the first pressure receiving portion 43 and the second pressure receiving portion 44 of the link member 4. Therefore, even if the operating knob is swung from the pressing start position to the pressing end position at this time, the pressing portion 24 and the second pressure receiving portion 44 do not contact each other, and the pressing portion 24 and the first pressure receiving portion 43 also contact each other. do not do. Therefore, the swing of the operation knob is not transmitted to the link member 4, and the lid can be maintained in the locked state.

  Similar to the side lock device of the first embodiment, the side lock device 1 of the second embodiment can greatly reduce the number of components, reduce the manufacturing cost, and has an anti-theft function.

  Furthermore, by providing the relief groove 45 in the link member 4, the pressing portion 24 does not interfere with the link member 4 even when the key cylinder 21 is disposed at the locking position. For this reason, the side lock device 1 of Example 2 operates with high reliability.

  In addition, since the first first pressure receiving portion 43 and the second pressure receiving portion 44 have a line-symmetric shape, the link member 4 is rotated in reverse by simply changing the relative positions of the key cylinder 21 and the link member 4 in the left-right direction. Can be made. And if the 1st connection part 62 of the 1st collar part 6 is connected to the 2nd input part 42 and the 2nd connection part 72 of the 2nd collar part 7 is connected to the 1st input part 41, the 1st collar part 6 Can be slid rightward, and the second flange 7 can be slid leftward. Therefore, in the side lock device of the first embodiment for the right-hand drive vehicle and the side lock device of the second embodiment for the left-hand drive vehicle, the key cylinder 21 is rotated in the same direction, and the key cylinder 21 and the link member 4 are rotated. Even if the left and right relative positions are interchanged, the first collar 6 can be slid in the right direction and the second collar 7 can be slid in the left direction. Therefore, in the side lock device of the first embodiment for the right-hand drive vehicle and the side lock device of the second embodiment for the left-hand drive vehicle, members other than the first collar portion 6 and the second collar portion 7 can be shared, Manufacturing cost can be reduced.

  In addition, by rotating the link member 4 in the reverse direction, the first flange portion 6 and the second flange portion 7 are not only one of the two input portions (the first input portion 41 and the second input portion 42) but the other one. Therefore, the degree of freedom in designing the first flange portion 6 and the second flange portion 7 is improved. Also according to this, according to the side lock device of the first embodiment and the side lock device of the second embodiment, the manufacturing cost can be reduced.

  The escape groove 45 of the link member 4 may be formed only between the second pressure receiving portion 44 and the rotating shaft 40.

( Reference example )
Hereinafter , a reference example of the link member 4 will be described.

The link member 4 is not limited to a cross shape, and can be formed in various shapes. For example, as shown in FIGS. 14 to 15, the link member 4 may be formed in a substantially T shape, and only one pressure receiving portion (first pressure receiving portion 43) may be formed on the link member 4. In this case, if the link member 4 is turned upside down, it can be used as the link member 4 (FIG. 14) of the side lock device 1 for right-hand drive vehicles, or the side lock device 1 for left-hand drive vehicles. It can also be used as the link member 4 (FIG. 15).

  Moreover, as shown in FIGS. 16-17, the link member 4 may be formed in a substantially bowl shape, and the 1st input part 41, the 2nd input part 42, and the pressure receiving part 43 may be arrange | positioned linearly. In this case, if the link member 4 is reversed left and right, it can be used as the link member 4 (FIG. 16) of the side lock device 1 for the right-hand drive vehicle, or the side lock device 1 for the left-hand drive vehicle. It can also be used as the link member 4 (FIG. 17). Also in this case, if the first input portion 41 and the second input portion 42 are separated from each other in the circumferential direction of the circle A around the rotation shaft 40, the first flange portion is rotated along with the rotation of the link member 4. 6 and the 2nd collar part 7 can be slid to a reverse direction.

  By the way, in order to slide the 1st collar part 6 and the 2nd collar part 7 largely, the 1st input part 41 and the 2nd input part 42 are separated widely in the circumferential direction of the circle A centering on the rotating shaft 40. It is preferable. In other words, as shown in FIG. 18, an angle θ formed by a straight line L1 that connects the rotation shaft 40 and the first input unit 41 and a straight line L2 that connects the rotation shaft 40 and the second input unit 42 is an obtuse angle. It is preferable that the angle is close to 180 °.
