A vehicle door lock device includes: a door lock body configured to be mounted to a door; an outside open lever mounted, in a pivotable manner, to a support shaft arranged on the door lock body; and a coupling member mounted to a pivot end portion of the outside open lever and having an insertion hole. An end portion of a rod on the outside open lever side is insertable through the insertion hole. The rod is configured to couple the outside open lever and an outside door handle configured to be mounted to a vehicle exterior side of the door. A mounting hole in the coupling member intersects the insertion hole, and the pivot end portion of the outside open lever has a mounting portion. The coupling member is fitted and fixed onto the mounting portion of the outside open lever through the mounting hole.

Door lock device for vehicle

A vehicle door lock device includes: a housing having an opening; a coupling member configured to be coupled to an operation mechanism arranged on a door; an operation lever arranged inside the housing and coupled to the coupling member through the opening; and a cover capable of opening and closing the opening and a coupling point between the coupling member and the operation lever. The cover is separate from the housing and assembled to the housing to be mountable on and demountable from the housing and rotatable between opened and closed states. Each of the housing and the cover includes: a temporary retaining mechanism to temporarily retain the cover in the opened state when the cover is assembled to the housing in a rotatable manner; and a full retaining mechanism configured to retain the cover in the closed state when the cover is rotatably assembled to the housing.

Vehicle door lock apparatus

A child protector mechanism includes a base member, a first lever, a second lever, a bush arranged between the first lever and the second lever, a child protector lever for moving the bush to an unset position or a set position, and a position retaining mechanism provided between the first lever and the bush. The bush is retained at each of the unset position and the set position by the position retaining mechanism provided between the first lever and the bush. Therefore, when assembling the bush and the first lever to the base member, the bush is retained at a predetermined position (for example, unset position) with respect to the first lever so that the bush does not move. Thus, the easiness of assembly of the bush and the first lever and the easiness of assembly of the child protector lever are excellent.

Child protector mechanism

Provided is a position holding device for a rotating lever, which includes a rotating lever and a torsion spring, and is capable of elastically holding the rotating lever at the two positions including a first position and a second position. The torsion spring includes a coiled part, and a first arm part and a second arm part each extending from the coiled part and facing each other across an engagement portion of the rotating lever. The first arm part includes a mountain portion formed at an intermediate portion thereof. The second arm part includes an urging portion. As a result, an urging force generated by the urging portion can be applied to the rotating lever as a braking force against an urging force generated by the mountain portion. Consequently, it is possible to reduce an abutment noise generated when the rotating lever abuts against a stopper member.

Position holding device for rotating lever and vehicle door lock device provided with said position holding device for rotating lever

An outside locking lever of a lever mechanism section in a lock mechanism of a vehicle door lock apparatus includes a hub portion being rotatable relative to a housing and having a connection subportion to which an inner end portion of a rod is connected in a torque transmittable manner; an arm portion extending radially outward from the hub portion and linked to an active lever; a hub-side engagement subportion provided on the hub portion and engaged in the vehicle interior-exterior direction with a first support portion of the housing; an arm-side engagement subportion provided on the arm portion and engaged in the vehicle interior-exterior direction with a second support portion of the housing; and a fragile portion provided between the two engagement portions and being breakable with a force of a predetermined value or greater. A space for allowing breakage at the fragile portion is provided within the housing.
