) to release the lock in the same way as the outside lever (21).

When the lock/unlock lever (44) is reversed by operating the key plate from outside the vehicle or by operating the knob inside the vehicle, the door lock device (1) becomes locked.

The lock/unlock lever (40 is rotated counterclockwise from the state shown in FIG. 2 and reversed to the locked position shown in FIG. 15. At this time, the engaging member (47) that was in the recess (57a) is The engaging end (4?e) rides on the inclined surface (5?c) of the boundary part (57e) of the cam part (57), and the retaining member (47) resists the biasing force of the biasing spring (47g). and is pushed back toward the swinging end (44b).It passes through the inclined surface (57c) and moves to the engaging end (47e).
When it comes to the inclined surface (5?d), the biasing spring (47g) works to help reverse the locking/unlocking lever (44), and the engaging end (47e) moves into the recess (5?b) with moderation. Engage and stop.

As a result, the sub-lever (45) is also rotated to the locked position via the reversing engagement pin (44a).

In the locked state, the arm base (44) of the lock/unlock lever (44) is

As shown in the figure, the retaining end (45c) is connected to the open lever (2).
5), the lock cannot be released because it does not engage with the lock release operation end (25a) and swings in vain.

However, the operation cable (42) was pulled by operating the inside handle inside the vehicle! In addition, since the cancel lever (43) is always rotated, the lock release end (43)
3d) is the unlocking operation end (
25a) to operate and unlock. Not only that, when unlocking, the canceling end (43c) pushes the canceling pushed end surface (45d) to reverse the sub-lever (45) to the unlocked position, and the locking/unlocking lever ( 44) also the cam part (5
7) and the engaging member (47), the door (A) is reversed to the unlocked position while performing a moderation operation, so that when the inside handle is operated to open the door (A), the door (A) will not be locked by mistake.

If you close the door (A) while it is locked, the latch (22)
When the striker (B1) engages with the ball (20), the open lever (25) also rotates and the lock release end (25a) is operated.
3d), the cancel lever (43) is rotated in the opposite direction, and the cancel end (43c) is moved to the canceled pushed end surface (4
Press 5d) to unlock. i.e. simply the door (A)
Just closing the door will unlock it, so you won't accidentally lock it.

When the outside handle is operated from the locked state and the door (A) is closed while pressing down the sub-lever (45), the cancel pushed end surface (45d) rises and the cancel end (43c) of the cancel lever (43) is engaged. The locked state will be maintained continuously. That is, keyless locking is performed without using a key plate.

When the door (A) is closed and the striker (Bl) enters the striker entry groove (34), the striker (B1)
the end of which contacts the receiving surface (28a) of the wedge (26),
Since it enters and stops while moving the wedge (26), the vertical direction of the striker (B1) is aligned with the wedge (26).
It is restrained and wobbling is suppressed.

In the door lock device (1), the engaging mechanism section (20) and the operating mechanism section (40) are separable, so that the specifications can be varied by changing the structure of each and combining them. I can do it. Something like that-
An example will be explained with reference to FIG.

The one shown in FIG. 20 is provided with an N1I2 inside lever (58) in place of the first inside lever (41) in the operating mechanism section (40). The second inside lever (58) is shown in phantom lines in FIGS. 2 and 9, and its radially extending lock release end (59a) engages with the pivot pin (45a) of the sub-lever (45). One end of the biasing spring (4B) is engaged with the operated end (59b), and the operated end (41) of the first inside lever (41)
The operated end (59c) is provided at a position deviated from d), and the pulley (60) is operated as shown by the imaginary line in FIG.
r, as shown in the cable (42), the operation cable (42) is wound from the opposite direction to the above, and the operated end (5θC
) can be engaged with the retaining piece (85) from the opposite direction.

In the door lock device (1) equipped with the operation mechanism section (40) having the second inside lever (58) shown in FIG. 20, the second inside lever (58) is rotated by pulling the operation cable (42). Then, the unlocking end (59a) operates the sub-lever (45) via the pivot pin (45a), so the unlocking operation is performed via the sub-lever (45) and the cancel lever (43) is rotated. Such a door lock device (1) has a door lock device (1) in which the sub-lever (45) or the lock/unlock lever (44) is not reversed to the unlocked state even when the door is in the locked state and the lock is released using the inside handle. It is commonly used for rear doors.

In addition, the cardinal branches (50a), (50b), (50
c) and the pivot part (36) are locked by a locking member (46), but the way of locking is shown as an example.
It goes without saying that other well-known structures may also be used. Also,
In the moderation mechanism provided between the lock/unlock lever (44) and the operation lock body (50), the engagement end (
47e), and a cam part (
57), but the cam portion may be provided on the retaining member and the engaging direction may be either inward or outward in the radial direction.

In addition, the base play) (10) and the meshing mechanism part (20)
The engaging and disengaging combination of the engaging mechanism portion (20) and engaging lock body (30) can be appropriately combined with each other, and there is no need to directly combine the engaging mechanism portion (20) and engaging lock body (30).
