The lock position A is shown by the solid line in FIG. By the rotation operation of the first locking lever 711, the link link 78 is moved downward in FIG. 9 via the link structure 79, whereby the slide pin 79 locks in the elongated hole 731a from the unlock position B. It moves to the position A and is disengaged from the first wall 421b (the door lock device 2 in the unlocked state is locked). In the locked state of the door lock device 2, even if the first opening lever 731 is rotated against the biasing force of the spring 735, the slide pin 733 and the first wall 421a do not engage with each other, and the latch The latched state of the mechanism 4 does not become the unlatched state (the door 1 in the closed state does not open). In addition, the lock knob 75, the lock key cylinder 76, or the motor 51 is operated in the other direction contrary to the above, and the first locking lever 711 is operated.
Is rotated in the opposite direction to the above, the state shown by the solid line in FIG. 10 to the state shown by the solid line in FIG. 9 (the state shown by the chain double-dashed line in FIG. 10), that is, the door lock device 2 in the locked state is unlocked. It becomes a state.

It is rotated counterclockwise from the double lock release position C shown in FIG. 10 to the double lock position D shown by a solid line in FIG. By the rotation operation of the double lock lever 722,
The slide bush 723 moves in the long hole 721b and comes to be positioned in the long hole 721a (the door lock device 2 in the double lock release state in the lock state becomes the double lock state in the lock state). At this time, the slide bush 723 is not restricted by the idling lever 721, and the elongated hole 721 is moved in accordance with the rotation of the first locking lever.
Since it can be moved within b, the rotation of the first locking lever 711 is not restricted but allowed. In the double lock state of the door lock device 2, the lock knob 75 is operated to operate the first locking lever 7
Even when trying to rotate 11, the idle lever 721 moves the spring 724 via the indoor lock link lever 74.
However, the slide bush 723 does not move the first locking lever 711 by moving in the elongated hole 721a. Therefore, even if the lock knob 75 is operated, the locked door lock device 2 will not be unlocked. This prevents the door lock device 1 in the locked state from being unlocked by a method other than the key, and improves the antitheft property. When the motor 61 is operated in the other direction to rotate the double lock lever 732 in the opposite direction to the above, the door lock device 2 from the state shown by the solid line in FIG. 11 to the state shown by the solid line in FIG. 10, that is, the double lock state. Is in the double lock released state.

In the state shown by the solid line in FIG. 11, the lock key cylinder 76 is operated to move the second locking lever 712 via the outdoor lock linking lever 75 from the state shown by the solid line in FIG. 12 to that shown in FIG. 1 to move the first locking lever 711 from the locked position B to the unlocked position A so that the state shown by the chain double-dashed line is obtained.
2 is rotated counterclockwise, the engagement leg 712a of the second locking lever 712 engages with the double lock lever 722, and the double lock lever 722 rotates clockwise as shown in FIG. Double lock release position C is reached. As a result, the door lock device 2 in the double lock state is in the double lock release state.

As a result, it is possible to allow the door lock device 2 in the double-lock state to be in the double-lock release state by the key, that is, to mechanically release the door lock device 2 so as to take measures against a failure of the double-lock actuator 6. There is. At this time, since the first locking lever 711 is also rotated counterclockwise in FIG. 12 by the second locking lever 712, the lock position A is changed to the unlock position B, and the door locking device 2 in the locked state is unlocked. Become. The above-described rotation of the double lock lever 712 by the second locking lever 712 also causes the output member 63 to rotate in the same manner.

In the door lock state of the door lock device 2 shown in FIG. 13 (the door lock device 2 is in the double lock release state and the door 1 is in the closed state), the first locking lever 711 is locked to the lock knob 75 and the lock key cylinder. 7
6. When the locking actuator 5 is rotated from the locked position A to the unlocked position B by operating the locking actuator 5 in the other direction (particularly, the lock knob 75), the linkage link 78 is normally generated by the rotation of the first locking lever 711.
12 tries to move upward in FIG. 12, but at this time, the outside handle 771 is operated in one direction (the first open lever 731 is rotated against the urging force of the spring 735). 14), the rotation of the first open lever 731 causes the slide pin 733 to engage with the second wall 421b to move the linkage link 78, that is, the long hole 731a of the slide pin 733.
Movement from the locked position A to the unlocked position B against the urging force of the spring 724 is restricted (pin 7
The long hole 792 moves with respect to 91). After that, when the one-way operation of the outside handle 771 is released,
As shown in FIG. 15, the engagement between the second wall 421b and the slide pin 733 is released, and the linkage link 78 is urged by the spring 724 so that the first locking lever 711 is released.
With respect to FIG. 12, the slide pin 733 is moved upward.
Changes from the lock position A to the unlock position B. As a result, the door lock device 2 in the locked state is unlocked. In this way, it is possible to switch the door lock device 2 from the locked state to the unlocked state when the outside handle 771 is operated (so-called comfort function function), and the door lock device 2 of the occupant gets on and off. The operability is improved.
