Abstract

In order to make it possible to definitively detect the open/closed state of a door, the present invention is equipped with: a body 4,a latch 7 for pivoting on the surface side of the body 4, and having a cam part 73 on the outer periphery thereof,a detection lever 30 for pivoting on the rear-surface side of the body 4 around a shaft 301 parallel to the axial center direction of the latch 7, having a detection part 302 for projecting to the surface side through a long hole 42 provided in the body 4 and sliding along the cam part 73 according to the rotations of the latch 7, also having a cam surface 303 provided on the opposite side from the detection part 302 so as to sandwich the shaft 301 therebetween, and having the ability to rotate to a position corresponding to the latch 7 rotation position as a result of the detection part 302 sliding along the cam part 73 according to the rotations of the latch 7,and a detection switch 31 capable of detecting the open/closed state of the door by turning on and off as a result of contact with and separation from the cam surface 303, according to the rotations of the detection lever 30, and provided on the rear-surface side of the body 4.

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 ...
