On the other hand, in the open state, particularly in the fully open state, the side door 1 is inclined outward in the vehicle width direction toward the front of the vehicle in the top view.

That is, in the present embodiment, the relative distance between the rear side connecting portion 22 and the front upper connecting portion 12a and the front lower connecting portion 12b in the vehicle width direction is smaller when the door panel is fully opened than when it is closed. As shown in the mechanical diagram of FIG. 4, the relative distance between the front upper connecting portion 12a and the front lower connecting portion 12b and the rear connecting portion 22 in the vehicle width direction at the time of closing is indicated by L1. Further, the relative distance at the time of full opening is indicated by L2. In this embodiment, L2 is set smaller than L1.

As described above, the side door 1 is tilted due to the change in the relative distance between the front upper connecting portion 12a and the front lower connecting portion 12b and the rear connecting portion 22 in the vehicle width direction, and as a result, the side door 1 The width of the entrance / exit can be expanded in the fully open state. Here, the width of the entrance / exit is the horizontal distance between the center pillar 33 located at the front portion of the door opening 35 and the front end of the side door 1, and is the distance indicated by X in FIG. 1 (B). .. Although X is omitted in FIG. 1 (A), the width of the entrance / exit is smaller than that in FIG. 1 (B) because it is in the middle of the opening operation.

In the present embodiment, as described above, when the side door 1 is opened from the closed state to the fully open state, the rear side connecting portion 22 has a vehicle width with respect to the front upper connecting portion 12a and the front lower connecting portion 12b. It is configured to be able to translate inward in the direction. Since the rear connecting portion 22 moves inward in the vehicle width direction, it is possible to suppress the amount of the side door 1 protruding outward in the vehicle width direction in the fully open state, and the width X of the entrance / exit is effectively expanded. be able to. Since the amount of protrusion can be suppressed, it is possible to prevent the side door 1 from coming into contact with an obstacle such as another vehicle parked next to the vehicle.

Further, the rear rotation shaft portion 23 of the present embodiment is attached to the quarter inner panel (vehicle body side portion) 31 so as to be able to translate in the vehicle width direction as described above, and the rear rotation shaft portion 23 is on the side. It is configured to move inward in the vehicle width direction during the opening operation of the door 1. That is, in this example, when the side door 1 is opened, the rear main body portion 21 moves inward in the vehicle width direction while rotating as the rear connecting portion 22 moves inward in the vehicle width direction. Therefore, the rear connecting portion 22 pushes the rear rotating shaft portion 23 inward in the vehicle width direction via the rear main body portion 21.

Since the rear main body 21 is a rigid body, the load is easily transmitted from the rear connecting portion 22 in the direction along the longitudinal direction of the rear main body 21. Therefore, the rear rotation shaft portion 23 can efficiently move inward in the vehicle width direction by the transmitted force pushed inward in the vehicle width direction.

The front rotary shaft portion 13 and the rear rotary shaft portion 23 of the present embodiment are arranged side by side in the vehicle front-rear direction, the front rotary shaft portion 13 is provided with the front meshing portion 15, and the rear rotary shaft portion 23 is provided with the front meshing portion 15. A rear meshing portion 25 is provided. The front meshing portion 15 is provided at the rear portion of the front rotary shaft portion 13, the rear meshing portion 25 is provided at the front portion of the rear rotary shaft portion 23, and the front meshing portion 15 and the rear meshing portion 25 in the meshed state are provided. Are facing each other. In the present embodiment, the rear meshing portion 25 is configured to move inward in the vehicle width direction while engaging with the front meshing portion 15 during the opening operation of the side door 1. In this example, as shown in FIG. 4, the front meshing portion 15 and the rear meshing portion 25 mesh with each other when the rear body portion 21 forms an angle β3 with respect to the rear body portion 21 in the closed state. For the first time, the rear rotating shaft portion 23 and the rear connecting portion 22 translate inward in the vehicle width direction by the distance L3 in FIG.

The front meshing portion 15 and the rear meshing portion 25 of the present embodiment have a so-called rack and pinion structure. As shown in FIGS. 5 and 6, the front meshing portion 15 has a small-diameter circular gear (pinion) provided on the outer periphery of the front rotary shaft 14 of the front rotary shaft portion 13. In this example, as the front rotation shaft 14 rotates, the pinion rotates coaxially with the front rotation shaft 14. The rear meshing portion 25 has a rack provided at the rear portion of the rear rotating shaft portion 23. The rack in this example faces the front of the vehicle and extends in the width direction of the vehicle.

When the side door 1 is opened, the front rotation shaft 14 of the front rotation shaft portion 13 and the rear rotation shaft 24 of the rear rotation shaft portion 23 rotate, and the front upper main body portion 11a, the front lower main body portion 11b, and the rear The side main body portion 21 rotates. As the front rotation shaft 14 rotates, the pinion of the front engagement portion 15 moves in the circumferential direction along the outer circumference of the front rotation shaft 14. In FIG. 5, the front meshing portion 15 moves counterclockwise. While the front meshing portion 15 is moving in the circumferential direction (position of the angle β3 in FIG. 4), the pinion of the front meshing portion 15 meshes with the rack of the rear meshing portion 25.

As shown in FIG. 6, from the state where the front meshing portion 15 and the rear meshing portion 25 start to mesh with each other, the front rotating shaft 14 and the rear rotating shaft 24 further rotate, and the front upper main body portion 11a and the front lower main body When the portion 11b and the rear main body portion 21 rotate, the front meshing portion 15 is pushed inward in the vehicle width direction as the front meshing portion 15 moves in the circumferential direction, and as a result, the rear rotating shaft portion 23 Moves inward in the vehicle width direction.

Since the front rotation shaft portion 13 and the rear rotation shaft portion 23 operate while meshing with each other at the meshing portion, the rotational movement of the front rotation shaft portion 13 is a linear motion of the rear rotation shaft portion 23 when the side door 1 is opened. Is converted to. As a result, the force acting on the rear meshing portion 25 from the front meshing portion 15 is transmitted to the rear rotating shaft portion 23, and the rear rotating shaft portion 23 can be efficiently moved inward in the vehicle width direction by the force.

Further, the front rotating shaft portion 13 of the present embodiment has a bulging portion 16 and a recess 17 as shown in FIGS. 5 to 8. The bulging portion 16 is formed by a part of the outer peripheral surface of the front rotating shaft 14 of the front rotating shaft portion 13 bulging outward in the radial direction as shown in FIGS. 5 and 6. The bulging portion 16 extends along the circumferential direction on the outer peripheral surface of the front rotating shaft 14 over about three-quarters of the circumference. The recess 17 is provided between one circumferential end of the bulge 16 and the other end.

Further, as shown in FIGS. 5 and 6, the front portion of the rear rotation shaft portion 23 is provided with a protruding portion 26 projecting forward toward the bulging portion 16. An inclined surface 27 corresponding to the outer surface of the bulging portion 16 is provided at the front end portion of the protruding portion 26. The inclined surface 27 is inclined inward in the vehicle width direction toward the rear of the vehicle. That is, the inclined surface 27 faces the front of the vehicle and the inside in the vehicle width direction. Further, the inclined surface 27 is curved so as to correspond to the curvature of the outer peripheral surface of the bulging portion 16.

As shown in FIG. 5, when the inclined surface 27 of the protruding portion 26 is in contact with the outer peripheral surface of the bulging portion 16, the outer surface of the bulging portion 16 is located inside the inclined surface 27 in the vehicle width direction. Therefore, the movement of the front rotating shaft portion 13 inward in the vehicle width direction is restricted. That is, the protruding portion 26 and the bulging portion 16 function as stoppers. During the opening operation of the side door 1, from immediately after the start of the opening operation to a predetermined timing, the inclined surface 27 is in contact with the outer surface of the bulging portion 16 located on the outer side of the inclined surface 27 in the vehicle width direction. The side rotation shaft portion does not move inward in the vehicle width direction. Until the predetermined timing (until the angle β3 in FIG. 4), the front upper main body portion 11a and the front lower main body portion 11b and the rear side main body are around the front rotation shaft 14 and the rear rotation shaft 24. Since the portion 21 is rotated, the bulging portion 16 that rotates together with the front rotation shaft 14 slides on the inclined surface 27. Since it is configured as described above, the bulging portion 16 and the inclined surface 27 of the protruding portion 26 come into contact with each other, so that the rear rotating shaft portion 23 moves inward in the vehicle width direction at an unintended timing. It can be effectively prevented.

On the other hand, as shown in FIG. 6, when the inclined surface 27 of the protruding portion 26 is separated without contacting the bulging portion 16 and the inclined surface 27 is located in the recess 17, the front meshing portion is formed. 15 and the rear meshing portion 25 mesh with each other, and the rear rotating shaft portion 23 moves inward in the vehicle width direction. When the bulging portion 16 slides on the inclined surface 27 and the bulging portion 16 and the inclined surface 27 do not come into contact with each other, that is, when the inclined surface 27 is located in the recess 17, the pinion of the front meshing portion 15 is set. By engaging with the rack of the rear meshing portion 25, the rear rotating shaft portion 23 can move inward in the vehicle width direction.

The angle formed on the front side of the vehicle by the front link member 10 is 90 degrees or more due to the front upper body portion 11a and the front lower body portion 11b of the front link member 10 and the reference line extending in the vehicle front-rear direction. Occasionally, the relative distance between the rear connecting portion 22 and the front upper connecting portion 12a and the front lower connecting portion 12b in the vehicle width direction is configured to change. That is, when the angle becomes 90 degrees or more, the pinion of the front meshing portion 15 is configured to mesh with the rack of the rear meshing portion 25.

The change in the relative position (meshing of the meshing portion) between the front upper connecting portion 12a and the front lower connecting portion 12b and the rear connecting portion 22 in the vehicle width direction occurs when the above angle is 90 degrees or more, so that the occupant When it becomes possible to get on and off, the width of the entrance and exit can be expanded. Further, since the maximum width of the swing amount (the amount of protrusion in the vehicle width direction) of the side door 1 when the door is fully opened is at a position where the angle is 90 degrees, the relative ratio is reached after the angle becomes 90 degrees or more. Since the position changes, it is possible to prevent the vehicle from coming into contact with an obstacle adjacent to the vehicle.

The description of the present embodiment is an example for explaining the present invention, and does not limit the invention described in the claims. Further, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.

In the present embodiment, by moving the rear connecting portion 22 inward in the vehicle width direction, the relative positions of the front upper connecting portion 12a and the front lower connecting portion 12b and the rear connecting portion 22 are changed. , Not limited to this. For example, the relative position may be changed by moving the rear connecting portion 22 outward in the vehicle width direction. Further, in the present embodiment, the rear rotation shaft portion 23 is moved inward in the vehicle width direction, but the present invention is not limited to this.
