Press 5d to unlock. That is, simply door A
Just closing the door will unlock it, so you won't accidentally lock it.

From the locked state, operate the outside handle and press down the outside lever 20 to open door A.
When closed, the cancel pushed end surface 45d rises and the cancel end 43c of the cancel lever 43 can no longer be engaged, and the locked state is continuously maintained. That is, keyless locking is performed without using a key plate.

When the door A is closed and the striker B1 enters the striker entry groove 34, the end of the striker B1 comes into contact with the receiving surface 26a of the wedge 28, and the striker B1 enters and stops while moving the wedge 26. is restrained in the vertical direction by the wedge 26, thereby suppressing wobbling.

In the door lock device 1, the meshing mechanism section 20 and the operating mechanism section 40 are separable, so that the specifications can be varied in a variety of ways by changing the structure of each and combining them. An example of such a device will be explained with reference to FIG.

What is shown in FIG. 20 is one in which a second inside lever 59 is provided in place of the first inside lever 41 in the operating mechanism section 40. As shown in FIG. The second inside lever 59 is shown in phantom lines in FIGS. 2 and 9, and has a radially extending lock release end 59.
a is engaged with the pivot pin 45a of the sub-lever 45, one end of the biasing spring 48 is engaged with the biased end 59b, and the position is offset from the operated end 41d of the first inside lever 41. An operated end 59c is provided at the operated end 59c, and the operating cable 42 is wound around the pulley 60 from the opposite direction as shown by the imaginary line in FIG.
An engagement piece 65 can be engaged with 9c from the opposite direction.

In the door lock device 1 equipped with the operation mechanism section 40 having the second inside lever 59 shown in FIG. Since the sub-lever 45 is actuated via the sub-lever 45, the unlocking operation is performed via the sub-lever 45, and the cancel lever 43 is not rotated. The lock lever 44 is never reversed to the unlocked state. Such a door lock device 1 is generally used for a rear door.

Note that although the pivot parts 50a, 50b, 50c and the pivot portion 36 are locked by a locking member 46, the locking method is merely an example, and other well-known structures may be used. Not even. Further, in the click mechanism provided between the lock/unlock lever 44 and the operating lock body 50, the engaging member 47 is provided with an engaging end 47e, and the operating lock body 50 is provided with an engaging end 47e.
7 is provided, but the cam portion may be provided on the engagement member and the engagement member may be reversed, and the engagement direction may be either inward or outward in the radial direction.

Further, the base plate 10, the meshing mechanism section 20, and the meshing lock body 30 can be combined with each other as appropriate, and it is not necessary to directly combine the meshing mechanism section 20 and the meshing lock body 30.

"Effects of the Invention" According to the automobile door lock device according to the present invention, by devising the arrangement without providing any special parts, it is possible to prevent thin rods etc. from reaching the parts that should be protected from theft. The theft prevention performance of the door lock device can be improved with almost no increase in cost, and since no extra space is required, there is no impact on other devices.
