Therefore, an opening 15c is formed in an intermediate portion of the first opening / closing link 15, and when the first opening / closing link 15 is rotated forward by the opening 15c, the first opening / closing link 15 is moved to the latch mechanism 7. To avoid interference. Moreover, weight reduction of the 1st opening / closing link 15 is achieved by the opening 15c.

The second opening / closing link 16 is a strip-like plate member having a narrower vertical width than the first opening / closing link, and is generally L-shaped in plan view. The second opening / closing link 16 is provided with rotating shafts 16a and 16b at both ends thereof, and one rotating shaft 16a provided at one end of the second opening / closing link 16 can rotate to the second column side bearing member 14. Is attached.

The two open / close links 15 and 16 configured in this way extend in the horizontal direction from the column-side bearing members 13 and 14, and are connected to the other rotating shafts 15 b and 16 b provided at the other end portions of the respective ends. The door-side bearing members 17 and 18 are respectively attached to be rotatable. The two door-side bearing members 17 and 18 have the same shape as the column-side bearing members 13 and 14 and are separated in the vertical direction. Specifically, the first door-side bearing member 17 to which the first opening / closing link 15 is attached is located on the lower side, and the second door-side bearing member 18 to which the second opening / closing link 16 is attached is located on the upper side. is doing. The two door-side bearing members 17 and 18 are attached to a door-side mounting seat 19. The door-side mounting seat 19 is a substantially rectangular plate member that is long in the vertical direction, and is attached to the through door 5. Below, the aspect in which the door side mounting seat 19 is attached to the penetration door 5 is demonstrated in detail.

The through door 5 has a substantially rectangular window portion 5b that is long in the vertical direction. This window part 5b is located in the intermediate part of the front panel 5a in the up-down direction, and is arranged side by side on the windows 2b and 2c formed in the front part 2a of the vehicle 2. A substrate 20 is provided below the window portion 5b so as to span the pair of frame members 6L and 6R. The board 20 has a substantially rectangular shape when viewed from the rear, and a mounting member 21 is provided on the rear surface of the board 20 at an intermediate portion in the vehicle width direction.

The mounting member 21 is substantially U-shaped in a plan view, and has flanges 21a and 21b extending outward in the vehicle width direction at both ends thereof. The mounting member 21 thus formed is arranged on the substrate 20 so that the middle portion of the mounting member 21 protrudes rearward and the two flanges 21a and 21b abut against the substrate 20, and the two flanges 21a, It is fixed by fastening 21b to the substrate 20. The rear surface portion of the mounting member 21 fixed in this manner is offset rearward from the substrate 20, and this rear surface portion is used as the mounting portion 21c. The attachment portion 21c is formed with a substantially rectangular attachment hole 21d that is long in the vertical direction, and the door-side attachment seat 19 is attached to the attachment portion 21c so as to close the attachment hole 21d.

The door side mounting seat 19 is provided inside the mounting member 21, that is, on the front surface of the mounting portion 21c. The door-side mounting seat 19 is arranged so that the two door-side bearing members 17 and 18 attached thereto protrude rearward from the door-side mounting seat 19 through the mounting holes 21d. The two door-side bearing members 17 and 18 are provided with the other rotation shaft 15b of the first opening / closing link 15 and the other rotation shaft 16b of the second opening / closing link 16 so as to be rotatable as described above. ing. The first opening / closing link 15 and the second opening / closing link 16 thus provided are provided on the through door 5 so as to be closer to the lower side than the window portion 5b.

As described above, the first opening / closing link 15 is spanned between the through door 5 and the through road column 8R and rotated around the axis L1 of one of the rotation shafts 15a so as to be opened and closed. The penetrating door is moved between the positions, and a weight support function is provided so that the penetrating door 5 can be supported alone. Here, as described above, the closed position is a position where the through door 5 is fitted into the through passage opening 4 and closes it, and the open position is out of the through passage opening 4 and ahead of it. And it is the position arranged on the right side. Further, the first opening / closing link 15 is configured in an approximately L shape in a plan view and is disposed so as to protrude rearward at the open position, so that when the through door 5 is opened, the opening for the through passage is formed. It moves to the position away from 4 to the right. Thereby, when the penetration door 5 is moved to an open position, the opening width of the opening 4 for penetration paths can fully be ensured.

The second opening / closing link 16 is configured to rotate around the axis L2 of one of the rotating shafts 16a in conjunction with the first opening / closing link 15 operating as described above. Similarly to the first opening / closing link 15, the second opening / closing link 16 is configured in an approximately L shape in plan view and is disposed so as to protrude rearward at the open position. Therefore, the second opening / closing link 16 can also be moved to the position away from the through passage opening 4 to the right when the through door 5 is opened, and the opening width of the through passage opening 4 is sufficiently large. Can be secured.

The axis L2 of the second opening / closing link 16 configured as described above is parallel to the axis L1 of the first opening / closing link 15, and the axis L3 of the other rotating shaft 16b and the first opening / closing link 15 are also provided. The other pivot shaft 15b is also parallel to the axis L4. Further, the axis L2 of the second opening / closing link 16 is shifted to the left rear in a plan view with respect to the axis L1 of the first opening / closing link 15, and the axis L3 of the second opening / closing link 16 is also first opening / closing. The link 15 is shifted to the left rear in plan view with respect to the axis L4 of the link 15. As described above, by providing the respective rotation shafts at positions parallel to each other in the side view and separated from each other in the plan view, the first opening / closing link 15 and the second opening / closing link 16 can function as a parallel link mechanism. The support structure 1 can move the through door 5 between the closed position and the open position while maintaining the posture of the through door 5 in the substantially same closed posture as when fitted in the through passage opening 4. It can be done. Here, the second open / close link 16 restricts the through door 5 from freely rotating with respect to the first open / close link 15 while the through door 5 is moved between the closed position and the open position. The through door 5 has a rotation restricting function for maintaining the posture of the through door 5 in the closed posture. Thereby, when returning the through-passage door 5 to the through-passage opening 4, the second opening / closing link 16 is fitted into the through-passage opening 4 with the through-door 5 being in the closed posture, and is inserted into the through-passage opening 4. 4 is closed.

<Operation of support structure for through door>
In the through-door support structure 1 configured in this way, when the closed through-door 5 is pulled or pushed forward by the handle 9 or the like, the first opening / closing link 15 and the second opening / closing link 16 are centered on the shaft cores L1 and L2. The penetrating door 5 rotates and moves to a closed position and an open position so as to draw an arc (refer to the one-dot chain line in FIG. 6). Further, the second opening / closing link 16 regulates the posture of the through door 5 when the second open / close link 16 moves from the closed position to the open position, and keeps the through door 5 in the closed posture. Thereby, the through-door support structure 1 can move the through-door 5 from the closed position to the open position with the closed posture by pulling or pushing the closed through-door 5 forward. Conversely, the through door 5 can be moved from the open position to the closed position in the closed position by pulling or pushing the open through door to the left rear, and the through door 5 can be used as it is without adjusting the position of the through door 5. It can be fitted into the opening 4 to close it.

In the through-door support structure 1 having such a configuration, the first opening / closing link 15 is configured to be wider and thicker in the vertical direction with respect to the second opening / closing link 16 so as to increase the support rigidity. The first opening / closing link 15 alone can stably support the through door 5 so as not to tilt without providing another link or slide mechanism on the upper side. In this way, the second opening / closing link 16 can be disposed below the window portion 5b of the through door 5 without being disposed near the roof structure of the vehicle 2 by being capable of being supported alone. In the parallel link mechanism, it is necessary to adjust the parallelism and position of the shaft cores L1 to L4. However, since the two open / close links 15 and 16 are gathered and brought close to the lower side of the window portion 15b, their axes While the cores L1 to L4 are viewed from each other, their parallelism and position can be adjusted, and attachment work and adjustment work are easy.

In the through-door support structure 1, for example, the column-side mounting seat 12, the two column-side bearing members 13, 14, the two opening / closing links 15, 16 and the door-side bearing members 17, 18 are assembled in advance. Can be a unit. By making it a unit, before attaching to the vehicle 2, the attachment surface attached to the through door 5 of the door-side bearing members 17, 18 moves substantially in parallel so that the through door 5 attached thereto moves while maintaining the closed posture. The column-side bearing members 13 and 14 can be attached to the column-side mounting seat 12 with high accuracy. By doing so, even if adjustment work due to a manufacturing error occurs between the through door 5 and the through passage pillar 8R, the door side bearing is mounted after the pillar side mounting seat 12 is attached to the link attachment plate 8a of the through passage pillar 8R. An adjustment liner 22 is provided in the gap between the members 17 and 18 and the door-side mounting seat 19 to fill the gap, and the mounting operation and adjustment are performed by attaching the door-side bearing members 17 and 18 to the door-side mounting seat 19 together with the adjustment liner 22. The work is finished. In this way, the mounting work and adjustment work of the column-side bearing members 13 and 14 with respect to the through-passage column 8R can be omitted, so that the mounting work and adjustment work of the through-door support structure 1 can be facilitated. Further, since the through door support structure 1 is a structure in which the through door 5 is supported by the two opening and closing links 15 and 16, the number of parts can be reduced as compared with the structure of the prior art in which guide rails and linear guides are provided. Manufacturing cost can be reduced. Further, since the operation can be confirmed and adjusted only by the through door support structure 1 before the through door 5 is attached, the adjustment work when the through door 5 is attached to the vehicle body 2 can be reduced.

Further, as described above, the through door 5 has a streamline shape such that the portion near the lower end protrudes forward, and the two open / close links 15 and 16 are provided around the lower abdomen of the through door 5. It has become. Accordingly, the dead space generated by making the through door 5 into a streamline shape can be effectively utilized and arranged.
