2. Description of the Related Art In a conventional door lock device, a latch which can be engaged with and disengaged from a striker and a locking plate which can be engaged with and disengaged from a latch are rotatably pivotally mounted in a storage part formed in a lock body, and the lock body is attached to the lock body. A rubber stopper is fitted and fixed in the recessed portion, and when the locking plate moves to the engagement position where it engages with the latch, it abuts the rubber stopper to cushion the sound when the locking plate is stopped. (For example, the actual Kaihei 6
-59659).

[0003]

However, in the conventional door lock device, since the locking plate is stopped by contacting it with the rubber stopper fitted in the recess formed in the lock body, the rubber contacting the locking plate is stopped. If the abutting portion of the stopper is cut or worn due to aging, etc., the stopping position of the locking plate will also shift due to deformation of the abutting portion of the rubber stopper,
This may cause various malfunctions.

In view of the above-mentioned problems, the present invention minimizes the change in the stop position of the operating lever even when the stopper is worn, and prevents various malfunctions. It is intended to provide a stopper support structure in a device.

[0005]

According to the present invention, the above problems can be solved as follows. (1) A stopper in a door lock device in which an operating lever movably supported by a body between an operating position and a stopping position is stopped at the stopping position by contacting a stopper fixed to the body. In the support structure, at the stop position, a stopper made of an elastic body having a first stopper portion that comes into contact with the operating lever is provided, and a portion of the stopper is abutted to prevent the stopper from moving toward the operating lever. A holding piece having a holding surface for stopping and a second stopper portion located slightly beyond the stop position is arranged near the stopper.

(2) In the above item (1), the stopper is a fitting portion for fitting with a holding portion provided on the body, and a connecting portion for connecting the fitting portion and the first stopper portion. And having the connecting part held between the body and the pressing piece.

(3) In the above item (1) or (2), the contact portion of the actuating lever is movably fitted in an elongated hole formed in the body, and the first stopper portion of the stopper is Insert into the long hole.

[0008]

The operating lever is stopped at the predetermined stop position without making a tapping sound by the contact portion contacting the first stopper portion of the stopper. Then the second
Since the stopper is located slightly beyond the stop position of the actuating lever, the actuating lever normally contacts only the first stopper portion of the stopper, never the second stopper portion, and operates. By the lever coming into contact with the first stopper portion, even if the stopper tries to bounce toward the operating lever side, the bounce of the stopper is prevented by the bounce prevention surface of the pressing piece.

In addition, if the stopper is worn, the first
When the stopper portion is retracted from the initial position, the operating lever comes into contact with the second stopper portion to stop the operating lever.
