Abstract

In order to enable open and closed states of a door to be surely detected: a body 4; a latch 7, which is pivotally supported on a surface side of the body 4 and has a cam portion 73 on an outer periphery thereof; a detection lever 30, which is pivotally supported on a reverse side of the body 4 by a shaft 301 parallel with an axial direction of the latch 7, has a detecting portion 302 that penetrates through an elongated hole 42 provided in the body 4 into to the surface side and slides along the cam portion 73 in association with rotation of the latch 7, and a cam surface 303 that is provided on an opposite side of the detecting portion 302 across the shaft 301, and is rotatable to a position corresponding to a rotational position of the latch 7 by the detecting portion 302 sliding along the cam portion 73 in association with rotation of the latch 7; and a detection switch 31, which is provided on the reverse side of the body 4 and is able to detect the open and closed states of the door by being turned ON and OFF by coming into contact with and separating from the cam surface 303 in association with rotation of the detection lever 30, are included.

Description

technical field [0001] The present invention relates to a vehicle door lock device having a detection switch for detecting a door opening and closing state. Background technique [0002] Conventionally, for example, as described in Patent Document 1, a door lock device for a vehicle is provided with a latch, a detection lever (a cam in Patent Document 1), and a detection switch on a synthetic resin main body fixed inside a door of a vehicle. The surface of the lock is integrally formed with a bulging part that bulges toward the axial direction of the lock, and the bulging part uses the detection rod to turn on or off the detection switch, thereby detecting the rotation position of the lock, that is, the opening and closing state of the door. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Publication No. 2533005 [0006] However, in the vehicle door lock device described in Patent Document 1, the detection lever and the ...
