In the rear sliding door 12, rollers R (not shown) are provided at the upper and lower portions of the front end side via support members, respectively, and rollers R (not shown) are provided at the middle portion in the vertical direction of the rear end side via support members. The sliding door 12 slides forward and backward as the rollers R roll on the rails 5 and 6.

[0031] The striker 14 is fixed to one of the surfaces of the pair of front and rear sliding doors 11 and 12 that face each other.

[0032] The fully closed locking device 15 is provided on the other side of the mutually opposing surfaces of the front and rear pair of sliding doors 11 and 12, and locks the sliding doors 11 and 12 when the sliding doors 11 and 12 are fully closed. Although not shown in the figure, the fully closed locking device 15 includes: a latch that can be engaged with the striker 14, a pawl that engages with the latch to restrict the rotation of the latch, and a release lever for releasing the engagement between the latch and the pawl.

[0033] The fully open locking device 20 is provided in each of the sliding doors 11 and 12. One fully open locking device 20 is provided in the upper part and the rear end side of the front sliding door 11, and the other fully open locking device 20 is provided in the upper part and the front end side of the rear sliding door 12. When the sliding doors 11 and 12 are fully opened, each fully open locking device 20 engages with a corresponding striker 16 of two strikers 16 fixed to both ends of the upper edge of the door opening 3 in the front-rear direction, thereby locking the sliding doors 11 and 12 in the fully open state.

[0034] The two strikers 16 include a base member 17 fixed to the vehicle body 2 and a striker body 18 supported by the base member 17. Figure 8 As shown, the striker body 18 is a substantially U-shaped member having a pair of legs 18a, 18b extending parallel to each other and a connecting portion 18c connecting the top ends of the pair of legs 18a, 18b to each other. The base ends of the pair of legs 18a, 18b are fixed to the base member 17. In addition, a notch 19 is formed on the side surface of the leg 18b on the vehicle interior side. Each striker 16 is fixed to the upper edge of the door opening 3 in such a manner that the pair of legs 18a, 18b extend in the up-down direction and are arranged in a direction from the vehicle interior side toward the vehicle exterior side.

[0035] like Figure 2 , Figure 4As shown, the fully open locking device 20 includes: a base member 28 fixed to the support member 13 of the sliding door 11, a latch 21 that can rotate relative to the base member 28 and can engage with the striker 16 when the sliding door 11 is fully opened, a pawl 22 that can rotate relative to the base member 28 and engage with the latch 21 to restrict the rotation of the latch 21, and a release lever 23 that releases the engagement between the latch 21 and the pawl 22. The latch 21 has two hooks 21a and 21b that extend at a slightly larger interval than the outer diameter of the leg 18a of the striker 16 and sandwich the leg 18a to engage with the leg 18a. The latch 21 is urged clockwise in the figure by a spring, and when the sliding doors 11 and 12 are fully opened, the leg 18a of the striker 16 rotates counterclockwise by pressing one of the hooks 21a. Then, by further rotating the latch 21 counterclockwise to engage the pawl 22 with the latch 21 , the leg portion 18 a of the striker 16 is sandwiched between the two hook portions 21 a and 21 b , and the sliding doors 11 and 12 are locked in the fully opened state.

[0036] The upper hook device 30 is provided on each of the sliding doors 11 and 12. One of the upper hook devices 30 is provided on the upper portion and the front end side of the front sliding door 11 (the end on the opposite side of the end where the one fully open locking device 20 is provided in the front-to-back direction), and the other upper hook device 30 is provided on the upper portion and the rear end side of the rear sliding door 12 (the end on the opposite side of the end where the other fully open locking device 20 is provided in the front-to-back direction). Each of the upper hook devices 30 engages with the striker 16 of the two strikers 16 respectively when the sliding doors 11 and 12 are fully closed, thereby restricting the displacement of the sliding doors 11 and 12 from the vehicle interior to the vehicle exterior.

[0037] like Figure 5 to Figure 7 As shown, the upper hook device 30 includes a base member 38, a latch 31 that is rotatable relative to the base member 38 and that is engageable with the striker 16 when the sliding doors 11 and 12 are fully closed, a pawl 32 that is rotatable relative to the base member 38 and that is engaged with the latch 31 to restrict the rotation of the latch 31, and a release lever 35 that releases the engagement between the pawl 32 and the latch 31. In this embodiment, the striker 16 that is engaged with the latch 31 of the upper hook device 30 and the striker 16 that is engaged with the latch 21 of the fully open locking device 20 described above are shared. Therefore, the number of components can be reduced and the cost can be further reduced.

[0038] like Figure 5 , Figure 6As shown in FIG. 1 , the latch 31 includes a rotation axis A1 extending in the vertical direction of the vehicle body 2 and supported by the base member 38 so as to be rotatable, and two hooks 31a and 31b extending at a distance larger than the distance between the pair of legs 18a and 18bd of the striker 16 and bent so that the top ends thereof are close to each other. That is, the latch 31 is formed in a substantially C-shape when viewed from the direction of the rotation axis A1. In addition, a spring 33 is provided on the rotation axis A1 of the latch 31, and the latch 31 is urged in the clockwise direction in the figure by the spring 33.

[0039] like Figure 5 , Figure 6 As shown in the figure, the ratchet 32 ​​includes: a rotation axis A2 extending parallel to the rotation axis A1 and supported by the base member 38 so as to be rotatable, a latch engaging portion 32a engaged with a hook portion 31a of one side of the latch 31, and a release lever engaging portion 32b engaged with the release lever 35. A spring 34 is provided on the rotation axis A2 of the ratchet 32, and the ratchet 32 ​​is urged by the spring 34 in the counterclockwise direction in the figure.

[0040] like Figure 7 As shown in FIG. 1 , the release lever 35 includes: a rotation axis A3 extending in a direction perpendicular to the rotation axes A1 and A2 and supported by the base member 38 so as to be rotatable, and a pawl engaging portion 35a engaging with the release lever engaging portion 32b of the pawl 32. A spring is provided on the rotation axis A3 of the release lever 35, and the release lever 35 is urged in the clockwise direction in the figure by the spring. When the release cable 36 is pulled by a motor (not shown) in a state where the latch 31 is engaged with the pawl 32, the release lever 35 is moved in the clockwise direction in the figure. Figure 7 When the release lever 35 rotates counterclockwise, the ratchet pawl 32 moves to the Figure 6 Thus, the engagement between the latch 31 and the ratchet pawl 32 is released.

[0041] In the hook device 30 configured as above, when the sliding doors 11 and 12 are fully closed, first, the hook portion 31a of the latch 31 located on the vehicle outer side contacts the leg portion 18a of the striker 16 (striker body 18) located on the vehicle outer side (see FIG. Fig. 9 (a)). When the sliding doors 11 and 12 slide further in the closing direction, the hook portion 31a of the latch 31 is pressed by the leg portion 18a of the striker 16, and the latch 31 rotates counterclockwise in the figure (see Fig. 9 (b)). When the latch 31 rotates, the hook portion 31b on the other side of the latch 31 on the vehicle interior side rotates to the other side of the leg portion 18b on the vehicle interior side of the striker 16, and the hook portion 31a on one side of the latch 31 engages with the latch engaging portion 32a of the pawl 32 (refer to Fig. 9(c)). Then, when the hook portion 31b on the other side is turned into the leg portion 18b on the other side of the striker 16, the sliding doors 11 and 12 are completely closed (refer to Fig. 9 (d)). As a result, the sliding doors 11 and 12 are pressed from the inside of the vehicle to the outside of the vehicle, and the hook portion 31b on the other side also engages with the foot portion 18b on the other side of the striker 16, thereby limiting the displacement of the sliding doors 11 and 12 to the outside of the vehicle. In this way, when the sliding doors 11 and 12 are fully closed, the latch 31 automatically rotates to the inside of the vehicle on the striker 16 and becomes able to engage with the striker 16, thereby more reliably limiting the displacement of the sliding doors 11 and 12 from the inside of the vehicle to the outside of the vehicle. As a result, the safety of the occupants can be ensured. In addition, if Figure 8 As shown in FIG. 1 , the other leg portion 18b located on the vehicle interior side of the striker 16 has a notch 19 formed therein, so when the sliding doors 11, 12 move from the vehicle interior side to the vehicle exterior side and the other hook portion 31b contacts the other leg portion 18b, the other hook portion 31b is moved as shown in FIG. Figure 8 As shown, the notches 19 are engaged with each other, so that engagement displacement can be prevented, and the slide doors 11 and 12 can be more reliably prevented from being displaced from the vehicle interior to the vehicle exterior.

[0042] In the above-mentioned embodiment, the sliding doors 11 and 12 are provided as a pair in front and rear, and slide on the vehicle body 2 in a manner of approaching and moving away from each other to open and close the door opening 3, but the sliding door can also be a single sliding door, and slide rearward relative to the door opening 3 to open and close the door opening 3.

[0043] In the above-described embodiment, the full-open locking device 20 and the upper hook device 30 are provided at the upper portions of the sliding doors 11 , 12 , but may be provided at the lower portions of the sliding doors 11 , 12 .

[0044] In the above-described embodiment, the latch 21 of the full-open locking device 20 and the latch 31 of the upper hook device 30 are engaged with the same striker 16 , but may be engaged with different strikers.

[0045] As mentioned above, although the form for implementing this invention was demonstrated using embodiment, this invention is not limited to such embodiment, It is a matter of course that it can be implemented in various forms within the range which does not deviate from the summary of this invention.
