  The rear end 32A of the door outer panel 32 and the rear end 45 of the door inner panel 40 are joined by hemming to form a joint 38. The joint portion 38 is formed at a portion on the vehicle width direction outer side of the rear side door 30 and on the vehicle rear side.

  The locking mechanism 50 shown in FIG. 2 is a mechanism for locking (latching) the rear side door 30 to the vehicle body 102. The locking mechanism 50 includes a striker 60, a striker locking portion 52, and a support portion 54.

  The striker 60 is provided on the second wall 22 of the side member outer panel 20. Specifically, the striker 60 is formed in a round bar shape, and is formed in a U-shape (U-shape) opened to the rear side of the vehicle in a plan view of the vehicle. More specifically, the striker 60 has a first rod portion 61, a second rod portion 62, and a third rod portion 63. The first rod portion 61 extends from the second wall portion 22 of the side member outer panel 20 substantially in the forward direction of the vehicle. The second rod portion 62 extends from the second wall portion 22 of the side member outer panel 20 substantially toward the front of the vehicle on the outer side in the vehicle width direction with respect to the first rod portion 61. The third rod portion 63 extends substantially in the vehicle width direction, and connects the front end portion of the first rod portion 61 and the front end portion of the second rod portion 62.

  The striker locking portion 52 is a member locked to the striker 60. The striker locking portion 52 is provided inside the rear side door 30. Specifically, the striker locking portion 52 is disposed between the first wall portion 41 of the door inner panel 40 and the door outer panel 32 in the vehicle width direction.

  The striker locking portion 52 has a hook-like portion, and the striker 60 (specifically, the second rod portion 62) is inserted into the recess of the hook-like portion and is locked to the striker 60. Ru.

  The support portion 54 has a function of movably supporting the striker locking portion 52 inward in the vehicle width direction. Specifically, the support portion 54 can move the striker locking portion 52 locked to the striker 60 inward in the vehicle width direction relative to the rear side door 30 inside the rear side door 30. In favor of The support portion 54 is fixed to the rear side door 30 inside the rear side door 30. Specifically, the support portion 54 is fixed to, for example, the door inner panel 40 (specifically, the first wall portion 41 and the second wall portion 42).

  The actuator 70 has a main body 72 and a rod 74 extending inward in the vehicle width direction from the main body 72. The actuator 70 is disposed inside the rear side door 30. Specifically, the actuator 70 is disposed at a position located outward in the vehicle width direction with respect to the striker 60 when the rear side door 30 is in the closed state. The main body 72 of the actuator 70 is fixed to, for example, the door inner panel 40 (specifically, the second wall portion 42) and the support portion 54.

  The rod 74 extends from the main body 72 toward the striker locking portion 52 (inward in the vehicle width direction), and the striker locking portion 52 is attached. Specifically, the striker locking portion 52 is fixed to the side portion (side surface) of the rod 74. Thereby, as shown in FIG. 3, the striker locking portion 52 moves inward in the vehicle width direction relative to the rear side door 30 by the extension of the rod 74. In other words, the extension of the rod 74 causes the main body 72 of the actuator 70 and the rear side door 30 to move outward with respect to the striker locking portion 52 in the vehicle width direction. The striker locking portion 52 is restricted from moving relatively inward in the vehicle width direction with respect to the rear side door 30 when the actuator 70 is not actuated.

  The tip of the rod 74 is in contact with the striker 60. Specifically, the tip end of the rod 74 is in contact with the tip end side (the third rod portion 63 side) of the second rod portion 62 of the striker 60 with respect to the position at which the striker locking portion 52 is locked.

  The actuator 70 is connected to a control unit 80 as a control unit that controls the drive of the actuator 70. The control unit 80 is connected to a collision detection sensor 82 as detection means for detecting a collision of the vehicle 100 and a collision prediction sensor 84 as prediction means for predicting a collision of the vehicle 100. When the collision detection sensor 82 detects a collision of the vehicle 100, the collision detection sensor 82 sends a detection signal to the control unit 80. When the collision prediction sensor 84 predicts a collision of the vehicle 100, the collision prediction sensor 84 sends a prediction signal to the control unit 80. Then, upon acquiring at least one of the detection signal and the prediction signal, the control unit 80 drives the actuator 70. As the collision detection sensor 82 and the collision prediction sensor 84, known sensors can be used.

  Then, when the control unit 80 drives the actuator 70, as shown in FIG. 3, the rod 74 of the actuator 70 extends (see arrow A), and the main body 72 of the actuator 70 and the rear side door 30 are engaged with the striker. It moves outward with respect to the stop 52 in the vehicle width direction. At this time, the extended rod 74 presses the striker 60 inward in the vehicle width direction at the tip end.

  Thus, as shown in FIG. 3, a part of the rear end side of the rear side door 30 (specifically, the door outer panel 32, the fourth wall portion 44 of the door inner panel 40 and the joint portion 38) is the side member outer panel 20. The rear side door 30 moves outward in the vehicle width direction with respect to the side member outer panel 20 so as to project outward in the vehicle width direction further than the outer surface (fifth wall portion 25) of (see arrow B). Specifically, the rear end portion of the rear side door 30 has a rear end portion on the outer side in the vehicle width direction with the front end portion as a rotation center so that a part on the rear end side protrudes outward in the vehicle width direction than the outer surface of the side member outer panel 20 Turn to

  The striker locking portion 52 moves inward in the vehicle width direction relative to the rear side door 30 together with the striker 60 while maintaining the state of being locked to the striker 60.

  Therefore, in the vehicle side structure 10, when the strike of the striker locking portion 52 is locked to the striker 60 when the collision of the vehicle 100 is detected or predicted, the rear side door 30 is moved against the side member outer panel 20 Move outward in the width direction.

  The actuator 70 may be configured such that the rod 74 does not press the striker 60 inward in the vehicle width direction at the time of driving.

(Function and effect of vehicle side structure 10)
The operation and effects of the vehicle side structure 10 will be described.

  In the vehicle side structure 10, as described above, when the striker locking portion 52 is locked to the striker 60 when the collision of the vehicle 100 is detected or predicted, the rear side door 30 is attached to the side member outer panel 20. Then, it moves outward in the vehicle width direction (see FIG. 3).

  Therefore, the rear side door 30 protrudes from the door opening 28 formed in the side member outer panel 20 to the outside in the vehicle width direction. Thus, even if the vehicle body 102 including the side member outer panel 20 is deformed due to the collision of the vehicle 100, the rear side door 30 can be prevented from being fitted into the door opening 28.

  Further, the rear side door 30 moves outward in the vehicle width direction in a state where the striker locking portion 52 is locked to the striker 60, so that the rear side door 30 can be prevented from being opened during a collision of the vehicle 100.

  Therefore, according to the vehicle side structure 10, the side member outer panel is suppressed by the collision of the vehicle 100 while suppressing the rear side door 30 from being opened during the collision of the vehicle 100 or before the collision of the vehicle 100 stops. Even if the vehicle body 102 including 20 is deformed, the rear side door 30 can be prevented from being fitted into the door opening 28. As described above, since the rear side door 30 can be suppressed from being fitted into the door opening 28, the openability of the rear side door 30 after the collision of the vehicle 100 is improved.

(First Modified Example of First Embodiment)
In the vehicle side structure 10 described above, the rear side door 30 is moved outward in the vehicle width direction with respect to the side member outer panel 20 by driving the actuator 70 in which the striker locking portion 52 is fixed to the rod 74. Not limited to this.

  For example, the configurations shown in FIGS. 4, 5, 6 and 7 may be used. In this configuration, the striker locking portion 52 is supported by the support portion 54 so as to be movable inward in the vehicle width direction. The striker locking portion 52 is provided with a rod-like shaft portion 180 as a locked portion. The shaft portion 180 extends from the striker locking portion 52 toward the front of the vehicle as shown in FIGS. 4 and 6.

  A locking member 182 for locking the shaft portion 180 is provided on the support portion 54. The locking member 182 is supported by the support 54 rotatably around an axis parallel to the shaft 180. As shown in FIG. 5, the locking member 182 has a hook-like portion at one end 182A. The shaft portion 180 is locked by the shaft portion 180 entering the recess 183 of the hook-like portion. By the shaft portion 180 being locked by the locking member 182, the movement of the striker locking portion 52 inward in the vehicle width direction is restricted. That is, the locking member 182 is fixed to the support portion 54.

  One end of a wire 184 inserted in a tube 185 such as a tube is attached to the other end 182 B of the locking member 182. Then, as shown in FIG. 7, when the other end portion 182 B of the locking member 182 is pulled by the wire 184, the locking member 182 rotates and the locked state of the shaft portion 180 is released. As a result, the striker locking portion 52 can move inward in the vehicle width direction.

  As shown in FIG. 4 and FIG. 6, the actuator 70 is provided on the support portion 54 on the vehicle lower side with respect to the striker locking portion 52. The rod 74 of the actuator 70 extends from the main body 72 inward in the vehicle width direction (side member outer panel 20 side). The rod 74 extends inward in the vehicle width direction, thereby pressing the first wall portion 21 of the side member outer panel 20 inward in the vehicle width direction.

  Further, the support portion 54 is provided with a lever 186 for pulling the other end of the wire 184. The lever 186 is operated by the extension of the rod 74 and is configured to pull the other end of the wire 184. Specifically, the lever 74 is operated by the rod 74 after the rod 74 starts to extend from the main body 72 until it contacts the side member outer panel 20.

  Therefore, before the rod 74 presses the side member outer panel 20, the locking member 182 pivots, and the locked state of the shaft portion 180 is released. That is, after the locked state of the shaft portion 180 is released, the rod 74 presses the side member outer panel 20.

  Then, upon acquiring at least one of the detection signal from the collision detection sensor 82 and the prediction signal from the collision prediction sensor 84, the control unit 80 drives the actuator 70.

  The control unit 80 drives the actuator 70 to extend the rod 74 of the actuator 70 (see arrow A), as shown in FIG. Between the start of the extension of the rod 74 from the main body 72 and the contact of the side member outer panel 20, the lever 186 is operated by the rod 74. As a result, the wire 184 is pulled, and the locked state of the shaft portion 180 by the locking member 182 is released. Furthermore, the rod 74 extended from the main body 72 presses the first wall portion 21 of the side member outer panel 20 inward in the vehicle width direction.

  Thereby, a part of the rear end side of the rear side door 30 (specifically, the door outer panel 32, the fourth wall portion 44 of the door inner panel 40 and the joint portion 38) is the outer surface of the side member outer panel 20 (fifth wall portion 25). The rear side door 30 is moved outward in the vehicle width direction with respect to the side member outer panel 20 so as to project further outward in the vehicle width direction than the arrow) (see arrow B). Specifically, the rear end portion of the rear side door 30 has a rear end portion on the outer side in the vehicle width direction with the front end portion as a rotation center so that a part on the rear end side protrudes outward in the vehicle width direction than the outer surface of the side member outer panel 20 Turn to

  At this time, the striker locking portion 52 moves inward in the vehicle width direction relative to the rear side door 30 while maintaining the state locked to the striker 60.

  Therefore, also in the first modification, when the striker locking portion 52 is locked to the striker 60 when the collision of the vehicle 100 is detected or predicted, the rear side door 30 is rotated relative to the side member outer panel 20. Move outward in the width direction.

(Second modification)
In the vehicle side structure 10 described above, the striker locking portion 52 moves inward in the vehicle width direction relative to the rear side door 30 so that the rear side door 30 maintains the locked state to the striker 60. Although the door 30 is configured to move outward with respect to the side member outer panel 20 in the vehicle width direction, the invention is not limited thereto.

  As shown in FIGS. 8 and 9, for example, the striker 60 moves toward the outer side in the vehicle width direction, and the rear side door 30 is maintained while the striker locking portion 52 is locked to the striker 60. May be structured to move outward with respect to the side member outer panel 20 in the vehicle width direction.

  Specifically, the structure of the second modification shown in FIGS. 8 and 9 is configured as follows, for example. In the structure of the second modification, the striker locking portion 52 is fixed to the support portion 54 and is configured not to move in the vehicle width direction with respect to the side member outer panel 20.

  In the structure of the second modification, a support portion 154 for supporting the striker 60 is provided on the side member outer panel 20. The support portion 154 has a function of movably supporting the striker 60 outward in the vehicle width direction with respect to the side member outer panel 20. Specifically, the support portion 154 supports the striker 60 in a state in which the striker 60 is locked so as to be movable relative to the side member outer panel 20 outward in the vehicle width direction. The support portion 154 is fixed to the side member outer panel 20 (specifically, the second wall portion 22). The second wall portion 22 is formed with an opening 22A through which the striker 60 moving to the outer side in the vehicle width direction with respect to the side member outer panel 20 passes.

  The actuator 70 is provided not on the rear side door 30 but on the vehicle body 102 side. Specifically, the main body 72 of the actuator 70 is fixed to the support portion 154. The rod 74 extends from the main body 72 toward the striker 60 (outside in the vehicle width direction), and the striker 60 is attached. Specifically, the striker 60 is fixed to the side (side) of the rod 74. Thereby, the striker 60 moves toward the vehicle width direction with respect to the side member outer panel 20 by the extension of the rod 74. In other words, the striker 60 is restricted from moving outward in the vehicle width direction with respect to the side member outer panel 20 when the actuator 70 is not actuated.

  Then, upon acquiring at least one of the detection signal from the collision detection sensor 82 and the prediction signal from the collision prediction sensor 84, the control unit 80 drives the actuator 70.

  Thereby, as shown in FIG. 9, the rod 74 of the actuator 70 is extended, and the striker 60 attached to the rod 74 is moved outward with respect to the side member outer panel 20 in the vehicle width direction. That is, the actuator 70 directly actuates the striker 60 to move the striker 60 outward with respect to the side member outer panel 20 in the vehicle width direction.

  Thereby, as shown in FIG. 9, a part of the rear end side of the rear side door 30 (specifically, the door outer panel 32, the door inner panel 40) via the striker locking portion 52 locked to the striker 60. Of the rear side door 30 with respect to the side member outer panel 20 so that the fourth wall portion 44 and the joint portion 38) of the rear side door 30 project beyond the outer surface (fifth wall portion 25) of the side member outer panel 20 in the vehicle width direction. Move in the direction outward (see arrow B).

  Specifically, the rear end portion of the rear side door 30 has a rear end portion on the outer side in the vehicle width direction with the front end portion as a rotation center so that a part on the rear end side protrudes outward in the vehicle width direction than the outer surface of the side member outer panel 20 Turn to

  At this time, the striker locking portion 52 moves outward with respect to the side member outer panel 20 with respect to the side member outer panel 20 along with the rear side door 30 while maintaining the state locked to the striker 60.

  Therefore, also in the second modification, when the collision of the vehicle 100 is detected or predicted, the rear side door 30 holds the vehicle relative to the side member outer panel 20 with the striker locking portion 52 locked to the striker 60. Move outward in the width direction.

Second Embodiment
The vehicle side part structure 200 which concerns on 2nd embodiment is demonstrated. 10 and 11 are plan sectional views showing the vehicle side structure 200. As shown in FIG.

  In the vehicle side structure 10 described above, the striker locking portion 52 is provided on the rear side door 30, and the striker 60 is provided on the side member outer panel 20. On the other hand, in the vehicle side part structure 200 which concerns on 2nd embodiment, the striker 60 is provided in the rear side door 30, and the striker latching part 52 is provided in the vehicle body 102 side.

  Specifically, the striker 60 is provided on the second wall portion 42 of the door inner panel 40. Specifically, the striker 60 is formed in a U-shape (U-shape) opening in the vehicle front side in a plan view of the vehicle. Specifically, the first rod portion 61 of the striker 60 extends from the second wall portion 42 of the door inner panel 40 substantially toward the rear of the vehicle. The second rod portion 62 extends from the second wall portion 42 of the door inner panel 40 substantially toward the rear of the vehicle on the inner side in the vehicle width direction with respect to the first rod portion 61. The third rod portion 63 extends substantially in the vehicle width direction, and connects the rear end portion of the first rod portion 61 and the rear end portion of the second rod portion 62.

  Specifically, the striker locking portion 52 is disposed on the inner side of the vehicle relative to the side member outer panel 20. The striker locking portion 52 has a hook-like portion, and the striker 60 (specifically, the second rod portion 62) is inserted into the recess of the hook-like portion and is locked to the striker 60. Ru.

  The support portion 54 has a function of movably supporting the striker locking portion 52 outward in the vehicle width direction. Specifically, the support portion 54 supports the striker locking portion 52 in a state of being locked to the striker 60 so as to be movable outward in the vehicle width direction with respect to the side member outer panel 20. The support portion 54 is fixed to the side member outer panel 20 inside the vehicle of the side member outer panel 20. Specifically, the support portion 54 is fixed to, for example, the second wall portion 22 of the side member outer panel 20.

  Openings 22A and 23A through which the striker 60 passes when the rear side door 30 is opened and closed are formed in the second wall portion 22 and the third wall portion 23 of the side member outer panel 20.

  The actuator 70 is disposed inside the vehicle relative to the side member outer panel 20. Specifically, the actuator 70 is disposed at a position located inside in the vehicle width direction with respect to the striker 60 when the rear side door 30 is closed. The main body 72 of the actuator 70 is fixed to, for example, the support 54. The rod 74 extends from the main body 72 toward the striker locking portion 52 (outside in the vehicle width direction), and the striker locking portion 52 is attached. Specifically, the striker locking portion 52 is fixed to the side portion (side surface) of the rod 74. Thereby, the striker locking portion 52 moves outward with respect to the side member outer panel 20 in the vehicle width direction due to the extension of the rod 74. In other words, movement of the striker locking portion 52 outward in the vehicle width direction with respect to the side member outer panel 20 is limited when the actuator 70 is not actuated.

  The tip of the rod 74 is in contact with the striker 60. Specifically, the tip end of the rod 74 is in contact with the tip end side (the third rod portion 63 side) of the second rod portion 62 of the striker 60 with respect to the position at which the striker locking portion 52 is locked.

  Then, upon acquiring at least one of the detection signal from the collision detection sensor 82 and the prediction signal from the collision prediction sensor 84, the control unit 80 drives the actuator 70.

  As a result, as shown in FIG. 11, the rod 74 of the actuator 70 is extended (see arrow A), and the striker locking portion 52 attached to the rod 74 extends outward with respect to the side member outer panel 20 in the vehicle width direction. Move it. That is, the actuator 70 directly operates the striker locking portion 52 to move the striker locking portion 52 outward in the vehicle width direction with respect to the side member outer panel 20. Furthermore, the extended rod 74 presses the striker 60 outward in the vehicle width direction at the tip end.

  Thus, as shown in FIG. 11, a part of the rear end side of the rear side door 30 (specifically, the door outer panel 32, the fourth wall portion 44 of the door inner panel 40 and the joint portion 38) is the side member outer panel 20. The rear side door 30 moves outward in the vehicle width direction with respect to the side member outer panel 20 so as to project outward in the vehicle width direction further than the outer surface (fifth wall portion 25) of (see arrow B).

  Specifically, the rear end portion of the rear side door 30 has a rear end portion on the outer side in the vehicle width direction with the front end portion as a rotation center so that a part on the rear end side protrudes outward in the vehicle width direction than the outer surface of the side member outer panel 20 Turn to

  At this time, the striker locking portion 52 moves outward with respect to the side member outer panel 20 with respect to the side member outer panel 20 together with the striker 60 and the rear side door 30 while maintaining the state of being locked to the striker 60.

  Therefore, in vehicle side structure 200, when the collision of vehicle 100 is detected or predicted, rear side door 30 holds the vehicle against side member outer panel 20 in a state where striker locking portion 52 is locked to striker 60. Move outward in the width direction.

  Therefore, the rear side door 30 protrudes from the door opening 28 formed in the side member outer panel 20 to the outside in the vehicle width direction. Thus, even if the vehicle body 102 including the side member outer panel 20 is deformed due to the collision of the vehicle 100, the rear side door 30 can be prevented from being fitted into the door opening 28.

  Further, the rear side door 30 moves outward in the vehicle width direction in a state where the striker locking portion 52 is locked to the striker 60, so that the rear side door 30 can be prevented from being opened during a collision of the vehicle 100.

  Therefore, according to the vehicle side structure 200, the side member outer panel is prevented by the collision of the vehicle 100 while suppressing the rear side door 30 from being opened during the collision of the vehicle 100 or before the collision of the vehicle 100 stops. Even if the vehicle body 102 including 20 is deformed, the rear side door 30 can be prevented from being fitted into the door opening 28. As described above, since the rear side door 30 can be suppressed from being fitted into the door opening 28, the openability of the rear side door 30 after the collision of the vehicle 100 is improved.

  The actuator 70 may be configured such that the rod 74 does not press the striker 60 outward in the vehicle width direction at the time of driving.

(Modification of the second embodiment)
In the vehicle side structure 200 described above, the actuator 70 directly moves the striker locking portion 52 to move the rear side door 30 outward in the vehicle width direction with respect to the side member outer panel 20. I can not. For example, as in the first modified example of the first embodiment described above, a locking member for locking the striker locking portion 52 is provided, and the locking state of the locking member is released, and the striker locking portion 52 is released. Alternatively, the rear side door 30 may be configured to be moved outward by pressing the rear side door 30 outward in the vehicle width direction with respect to the support 54.

  In the above-described vehicle side structure 200, the striker locking portion 52 is moved outward along with the rear side door 30 and the striker 60 in the vehicle width direction, and is maintained in a state of being locked to the striker 60. However, it is not limited to this. For example, the striker 60 moves inward in the vehicle width direction relative to the rear side door 30 so that the rear side door 30 is the side member outer panel 20 while the striker locking portion 52 is kept locked. May be moved outward in the vehicle width direction.

(Modification of the first embodiment and the second embodiment)
In the first embodiment and the second embodiment, although the example in which the rear side door 30 is used as the side door has been described, the present invention is not limited thereto. The side door may be, for example, a front side door that opens and closes a door opening formed on the vehicle front side with respect to the center pillar 104.

  The present invention is not limited to the above embodiment, and various modifications, changes, and improvements can be made without departing from the scope of the invention.
