Hereinafter, embodiments for carrying out the present invention will be described. The following description of preferred embodiments is merely exemplary and is not intended to limit the invention, its applications or its uses.

As shown in FIG. 1, the vehicle V according to the embodiment of the present invention is a two-door hardtop type passenger car, and includes a pair of left and right sashless type side doors 1. Since this vehicle V has a symmetrical structure, the right side portion will be mainly described below. Further, in the figure, the arrow F direction indicates the front, the arrow U direction indicates the upward direction, and the arrow O direction indicates the outward direction in the vehicle width direction.

The vehicle V includes a side sill 2 extending in the front-rear direction, a hinge pillar 3 erected above the side sill 2, a center pillar 4 erected above the side sill 2 behind the hinge pillar 3, and a hinge pillar 3. It has a front pillar 5 extending upward and rearward from the upper end portion of the above, and a roof side rail 6 and the like connecting the front pillar 5 and the upper end portion of the center pillar 4. The opening 7 for entering and exiting the vehicle interior is formed in the area surrounded by the side sill 2, the hinge pillar 3, the center pillar 4, the front pillar 5, and the roof side rail 6 which are the vehicle body side skeleton members in the vehicle body side portion 8. It is closed by the side door 1.

The side door 1 has an inner handle 9 for opening the side door 1 from the vehicle interior, and an inner handle switch 9a (not shown later) for detecting the operation of the inner handle 9. Further, in the portion of the vehicle body side portion 8 adjacent to the rear end of the side door 1, the portion of the vehicle body side portion 8 is recessed inward (on the vehicle interior side) in the vehicle width direction so as to be connected to the trailing edge of the opening 7. It has a recess 10 formed by inserting it, and is equipped with a cover member 11 that covers the recess 10. Further, the outer surface portion 1a of the side door 1 is provided with a key cylinder 16 and a door lock switch 17.

As shown in FIG. 2, a pair of upper and lower hinges 12 are fastened and fixed to the front portion of the side door 1. A pair of hinges 12 are fastened and fixed to the hinge pillar 3, and the side door 1 is rotatably supported around the rotation axis of the hinge 12 extending in the vertical direction.

As shown in FIGS. 2 to 4, the rear end portion of the side door 1 is equipped with a door latch device 20 that engages with the striker 14 arranged at the trailing edge portion of the opening 7. When the side door 1 is closed, the striker 14 is received from the door latch opening 15 at the rear end of the side door 1, and the latch 21 of the door latch device 20 engages with the striker 14. For example, when this engagement is released by operating the inner handle 9 of the side door 1, the side door 1 can be opened.

The door latch device 20 will be described with reference to FIGS. 3 to 7.
The door latch device 20 has a substantially U-shaped latch 21 that can rotate about a latch shaft 21a whose axis extends in the front-rear direction of the side door 1. It also has an electric latch drive motor 22 that rotates the latch 21. In the unlatched state with the side door 1 open, the latch 21 is urged to maintain the striker 14 in an acceptable position, and when the side door 1 is closed, the open side of the substantially U-shaped latch 21. The striker 14 is accepted from (see FIG. 5).

The latch 21 that has received the striker 14 rotates about the latch shaft 21a due to the reaction force when the striker 14 is pushed by the inward movement of the side door 1 in the vehicle width direction, and enters a half-latch state (see FIG. 6). After that, the full latch state (see FIG. 7) is reached, and the side door 1 is completely closed.

In the closed side door 1, for example, the latch drive motor 22 is driven by operating the inner handle 9, the latch 21 is rotated in the direction from the full latch state to the unlatch state, and the side door 1 moves outward in the vehicle width direction. It becomes an unlatch state. The unlatched side door 1 can be easily opened by hand.

It is configured as follows.

For example, a worm gear is composed of a worm driven by a latch drive motor 22 and a worm wheel that rotates a latch shaft 21a. Then, by driving the latch drive motor 22, the latch shaft 21a and the latch 21 are rotated in the direction from the full latch state to the unlatch state. On the other hand, even if an attempt is made to rotate the latch 21 from the full latch state to the unlatch state, it is difficult to rotate the latch 21 due to the self-locking of the worm gear. The side door 1 does not open easily even if the above is added.

Utilizing the fact that the side door 1 does not open unless the latch drive motor 22 is driven, the door lock mechanism electrically prohibits the drive of the latch drive motor 22 to put it in a locked state. In the unlocked state, the latch drive motor 22 can be driven, and the locked state and the unlocked state can be easily electrically switched.

In the half-latch state, even in the so-called half-door state where the weather strip 13 (see FIG. 4), which enhances the airtightness of the side door 1 when the side door 1 is closed, does not reach the full latch state, the side can be easily sided for safety. The door 1 is provided so as not to open. The half-latch state and the full-latch state are the latch states in which the latch 21 is engaged with the striker 14. When the unlatch state is changed to the half-latch state, the latch drive motor 22 may be driven to rotate the latch 21 so as to be in the full latch state to improve safety.

Next, the recess 10 of the vehicle body side portion 8 and the cover member 11 will be described.
As shown in FIGS. 1, 8, 9, and 10, the recess 10 is formed in a portion of the vehicle body side portion 8 adjacent to the side door 1 so as to be continuous with the trailing edge of the opening 7. For example, the case 10a made of synthetic resin divides the passenger compartment side of the recess 10 and a part of the top and a part of the bottom, and the case 10b made of synthetic resin separates the rear part of the recess 10, the rest of the top, and the rest of the bottom. It is partitioned.
