The open link 30 that can be transmitted to the vehicle 9 extends along a plane orthogonal to the longitudinal direction of the approach passage 40, and is arranged on the side of the bulging portion 41 on the side opposite to the entrance 40a of the approach passage 40. It is possible to perform stroke operation and swing operation in the plane.

Therefore, the bulging portion 41 of the casing main body 37 of the casing 26 is fixed to the inner panel 25 _F.
The open link 31 can be operably arranged by effectively utilizing the space occupying between the end wall portion 25 a of the glass sash 23 _F and the end portion of the glass sash 23 _F. (Glass sash 23
_Since it is not necessary to secure a large space on the _F side), a relatively large empty space can be secured between the door lock device 22 _F and the glass sash 23 _F. Further, the space for disposing the open link 31 on the side of the bulging portion 41 on the side opposite to the entrance 40a of the approach passage 40 can be small,
Therefore, the space occupied by the door lock device 22 _F in the thickness direction of the front side door D _F also becomes small. Thus, the front side door D _F of the internal structure and the front side door D _F The cover 77 thereby it becomes possible to increase the degree of freedom in thickness settings, the casing 26 covers the locking state switching device 79 _F Installed, front side door D
_Even if the special tool is inserted into the front side door D _F when _F is in the locked state, it is impossible to engage the special tool with the open link 31 or the locking lever 32.

Since the elastic stopper 68a is formed integrally with the covering material 68 of the ratchet 28, the impact sound generated when the elastic stopper 68a comes into contact with the casing main body 37 in order to regulate the rotating end is prevented by the elastic stopper 68a. It is possible to prevent the generation of noise by absorbing by the elastic action.

Furthermore, since the elastic stopper 68a is sandwiched between the casing main body 37 and the engaging arm portion 121 of the ratchet lever 29 at the time of contact with the casing main body 37, the elastic stopper 68a is engaged with the engaging arm portion 1 of the ratchet lever 29.
When the elastic stopper 68a is supported by 21, the durability of the elastic stopper 68a can be improved. Moreover, the elastic stopper 68a
Is projected from the ratchet 28 in a direction parallel to the rotation axis of the ratchet 28, so that the stopper is orthogonal to the rotation axis as compared with the case where the stopper is projected in the radial direction from the rotation axis. The space occupied by the ratchet 28 in the plane can be reduced, and the ratchet 2
The size of the casing 26 can be reduced, and the size of the casing 26 can be reduced.

A support plate 126 is elastically engaged with the cover body 80 from the casing 26 side while the relative position of the 126 with the cover body 80 in a plane orthogonal to the operation direction 85 is unchanged, and constitutes a cover 77 together with the cover body 80. 81 is
The actuator 126 is coupled to the cover body 80 so as to prevent the actuator 126 from being separated from the cover body 80. Therefore, the actuator 126 is fixedly supported by the cover 77 by connecting the support plate 81 to the cover body 80 to configure the cover 77 in a state where the actuator 126 is elastically engaged with the cover body 80. Become.
As a result, the actuator 126 can be easily assembled without using fastening parts such as screws, and the assembling workability can be improved.

Moreover, the output shaft 13 of the actuator 126
Since 3 is coaxially connected to the locking lever 32,
It is not necessary to provide a connecting member between the output shaft 133 of the actuator 126 and the locking lever 32,
Not only can the number of parts be reduced to improve the ease of assembly, but also the power transmission efficiency between the actuator 126 and the locking lever 32 can be improved.

Further, due to the relative arrangement of the knob lever 34 _F into which the operating force corresponding to the operation of the lock knob is input and the lock knob, it is difficult to directly connect the operating force transmitting member such as a rod connected to the lock knob to the knob lever 34 _F. The operating force transmitting member and the knob lever 34 are
