The latch 41 is released from the latch 41c to release the latching state between the latch 41 and the striker 45.

In the door lock device, the latch 4
1 and an operation to form a locked state in which the latched state of the striker 45 cannot be released, an operation to form an unlocked state in which the latched state of the latch 41 and the striker 45 can be released, and a door in the unlocked state. The operation in the case of performing the opening / closing operation will be described with reference to the following eight examples.

The first operation is as follows.
When the door is in the unlocked state shown in FIG. 7, the door can be opened by operating the inside handle in the vehicle.
In the door lock device, when the inside handle is opened, the second inside lever 51 rotates clockwise in FIG. 1 via the inside cable 52, and rotates the first inside lever 21 clockwise in FIG. . First
When the inside lever 21 rotates clockwise in FIG. 7, its tip engages with the lower surface of the engagement piece 23 c of the open link 23 to push the open ring 23 upward, and the open link 23 The upper edge of the portion 23c is engaged with the engagement piece 32a of the lift lever 32 so that the lift lever 32
Is rotated, and the lift lever 32 rotates the pawl 42 to be disengaged from the latch portion 41c of the latch 41.

As a result, the rotation of the latch 41 is released by the pawl 42, and the latch 41 is rotated and returned by the urging force of the torsion spring 43. When the latch 41 moves in the direction away from the striker 45 by the force to open the door, the latch 41 41 is released from the striker 45 by releasing the hooked state with the striker 45 while rotating and returning. That is, by opening the inside handle, the latch 4
The locked state between 1 and striker 45 can be released and the door can be opened.

The second operation is as follows.
When the door is in the unlocked state shown in FIG. 7, the door can be opened by operating the outside handle outside the vehicle. In the door lock device, when the outside handle is opened, the open lever 31 rotates against the torsion spring 31b to push the open link 23 upward, and as shown in FIG.
3 engages the upper end edge of the engagement piece 23c with the engagement piece 32a of the lift lever 32 to rotate the lift lever 32;
The lift lever 32 rotates the pawl 42 and the latch 41
From the hook 41c. In this case,
The cancel lever 22 is rotated clockwise in the figure by the action of the first engaging groove 23a of the open link 23 and the engaging pin 22b of the cancel lever 22.

As a result, the rotation of the latch 41 is released by the pawl 42, and the latch 41 is rotated and returned by the urging force of the torsion spring 43. When the latch 41 moves in the direction away from the striker 45 by the force to open the door, 41 is released from the striker 45 by releasing the hooked state with the striker 45 while rotating and returning. That is, by the opening operation of the outside handle, the locked state of the latch 41 and the striker 45 can be released and the door can be opened.

The third operation is an operation for forming a locked state in which the latched state of the latch 41 and the striker 45 cannot be released by operating the lock knob in the vehicle. When the door lock device is in the unlocked state shown in FIG. 7, when the locking cable 53 is operated by the locking operation of the lock knob, the locking lever 24 is rotated, and the active lever 27 is rotated counterclockwise in the drawing. With the connection of the open link 23 to the open lever 31 as a fulcrum, the unlocked position shown in FIG. 7 (the operating position for forming the unlocked state) is shifted from the locked position shown in FIG. 8 (the operating position for forming the locked state). Tilt (move). For this reason, even if the open link 23 is moved as shown in FIG. 10 by opening the inside handle or the outside handle, the open link 23 does not engage with the lift lever 32, and the lift lever 32 and the pawl 42 do not rotate. . As a result, even if the inside handle or the outside handle is opened, the latch 41 and the striker 4 are not opened.
An unlocked state in which the locked state with No. 5 can be released is not configured, and the locked state is maintained and the door is not opened. In this case (when the open link 23 is tilted from the unlock position shown in FIG. 7 to the locked position shown in FIG. 8), the cancel lever 22
3 and is rotated in the counterclockwise direction in the figure by the action of the first engagement groove 23a and the engagement pin 22b of the cancel lever 22.

The fourth operation is an operation for configuring the door lock device into a locked state and an unlocked state by rotating the key cylinder by a key blade outside the vehicle. In the door lock device, when the key cylinder is rotated by the key blade, the key lever 28 is rotated, and the active lever 27 is selectively moved to the position shown in FIG. To rotate. Thus, the active lever 27 selectively moves the open link 23 between the unlock position shown in FIG. 7 and the lock position shown in FIG. For this reason, by the rotation operation of the key cylinder by the key blade, the latched state between the latch 41 and the striker 45 is unlocked by opening the outside handle, and
A lock state that cannot be released can be selectively configured.

In the fifth operation, the electric motor 25 is driven by, for example, a remote control operation of a lock / unlock switch provided on the key blade outside the vehicle, so that the door lock device is put into a locked state and an unlocked state. It is an operation to do. In the door lock device, when the lock / unlock switch of the key blade is operated, the electric motor 25 rotates to rotate the wheel gear 26 by a predetermined amount via the worm 25a. Either the pin 26a or 26b is selectively engaged with a part of the engagement recess 27c of the active lever 27, and the active lever 27 is rotated between the position shown in FIG. 7 and the position shown in FIG. Thus, the active lever 27 selectively moves the open link 23 between the unlock position shown in FIG. 7 and the lock position shown in FIG. Therefore, by operating the lock / unlock switch of the key blade, the locked state of the latch 41 and the striker 45 is selected between an unlocked state that can be released by opening the outside handle and a locked state that cannot be released. It can be configured in a typical manner.

In a sixth operation, the door lock device is configured to be in a locked state by manually operating a lock knob with the door opened, and the door is closed without operating a door handle such as an outside handle or an inside handle. This is the operation (cancel operation) when the operation is performed. In the door lock device, when the door is closed, the pawl 42 rotates with the rotation of the latch 41 by the striker 45, and the lift lever 32 is indicated by a solid line from the position indicated by the two-dot chain line in FIG. To the position, and press the cancel lever 22
Is rotated from the position indicated by the two-dot chain line in FIG. 11 to the position indicated by the solid line. For this reason, the cancel lever 22 moves the open link 23 at the lock position shown by the two-dot chain line to the unlock position shown by the solid line via the engagement pin 22b. As a result, the latching state between the latch 41 and the striker 45 is released to an unlocked state, and the door can be opened by a subsequent opening operation of a door handle such as an outside handle or an inside handle.

The seventh operation is performed when the door lock device is locked by manual operation of the lock knob with the door opened, and the door is closed with the outside handle opened. Operation (keyless lock operation). In the door lock device, when the outside handle is opened in the locked state, as shown in FIG. 12, the open lever 31 is rotated and the open link 23 is pushed upward, and the cancel lever 22 is pressed. Of the open link 23
Is in a free state at a portion below the first engagement groove 23a.

Therefore, when the door is closed in this state, the pawl 42 and the lift lever 32 are rotated in accordance with the rotation of the latch 41 by the striker 45, and the cancel lever 22 is moved clockwise in FIG. It turns, but the engagement pin 22 b of the cancel lever 22 is
Of the open link 2 in the first engagement groove 23a.
3 is not moved to the unlock position, and the open link 23 is held at the lock position. Therefore, when the door is closed, the door lock device can be configured to be in a locked state in which the locked state between the latch 41 and the striker 45 cannot be released. When the opening operation of the outside handle is stopped after the door is closed, the state shown in FIG. 12 is changed to the state shown in FIG. 8, and the locked state is maintained.

In an eighth operation, when the door lock device is in a locked state where the latching state between the latch 41 and the striker 45 cannot be released, the inside handle is opened to cancel the locked state and to release the door. This is an operation (one-motion operation) in which the opening operation can be performed continuously. In this door lock device, when the inside handle is opened, the second inside lever 51 and the first inside lever 51 are opened.
The inside lever 21 rotates integrally, and first, the engagement protrusion 21c of the first inside lever 21 rotates the cancel lever 22, and the open link 23 at the lock position shown by the two-dot chain line in FIG. , And the active lever 27 and the idle lever 28 are turned from the lock position shown by the two-dot chain line in FIG. 13 to the unlock position shown by the solid line, and thereafter,
The open link 23 is pushed up by the first inside lever 21 to rotate the lift lever 32 and rotate the pawl 42. Thereby, the door can be opened.

As described above, in the door lock device, all the constituent members of the first operating mechanism 20 and the second operating mechanism 30 are housed in the closed housing 10 and are exposed to the outside of the housing 10. As a structure not to let
