DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper support structure for a door lock device in which an operating lever supported by a body is brought into contact with a stopper to stop at a predetermined stop position. .

[0002]

2. Description of the Related Art In a conventional door lock device, a latch which can be disengaged from a striker and a locking plate which can be disengaged from a latch are pivotally connected to a lock body in a storage portion formed in the lock body. The rubber stopper is fitted and fixed in the recessed portion, and when the locking plate moves to the engagement position where the latch is engaged, the rubber stopper comes into contact with the rubber stopper, thereby reducing the impact sound when the locking plate stops. (For example,

[0003]

However, in the conventional door lock device, the locking plate is stopped by bringing the locking plate into contact with a rubber stopper fitted in a concave portion formed in the lock body. If the abutting part of the stopper is cut or worn due to aging, etc., the stop position of the locking plate also shifts according to the deformation of the abutting part of the rubber stopper,
There is a risk of causing various malfunctions.

[0004] In view of the above 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 an object to provide a stopper support structure in the device.

[0005]

According to the present invention, the above-mentioned problem is solved as follows. (1) A stopper in a door lock device in which an operation lever movably supported by a body between an operation position and a stop position abuts on a stopper fixed to the body to be stopped at the stop position. in the support structure, the stop position, a contact portion of the actuating lever and the first stopper portion that abuts, is provided in the body, and the side opposite the abutment of the actuating lever is defined so as to open a fitting portion fitted into the holding portion, the stopper made of an elastic body having a connecting portion for connecting the first stopper portion and the fitting portion is provided, fitted in the stopper
A holding piece having a pressing surface that abuts on the joint portion and prevents the movement of the stopper toward the operation lever and a second stopper portion that is located slightly beyond the stop position is disposed near the stopper. The connecting portion of the stopper is sandwiched between the holding piece and the body. (2) In the above item (1), the contact portion of the operating lever is movably fitted into the elongated hole formed in the body, and the first stopper portion of the stopper is fitted into the elongated hole.

(2) In the above item (1), the operation lever
When the abutment movably fits into the long hole drilled in the body
In both cases, fit the first stopper part of the stopper into the slot
Enter.

[0007]

The operation lever is stopped at a predetermined stop position without generating a tapping sound when the contact portion contacts the first stopper portion of the stopper. Then the second
Since the stopper is located slightly beyond the stop position of the operating lever, the operating lever normally only contacts the first stopper portion of the stopper and does not contact the second stopper portion. When the lever comes into contact with the first stopper portion, even if the stopper attempts to rebound toward the operation lever, the rebound of the stopper is prevented by the rebound prevention surface of the pressing piece.

Further, the first member may be worn due to wear of the stopper.
In the case where the stopper portion has receded from the initial position, the operation lever is stopped by the operation lever contacting the second stopper portion.
