When the rack 7 rotates in the forward direction and the rack 18 slides toward the output lever 13 in the first direction, the deadlock release position G is released, and the pin pushing portion 16b moves the first engaging portion of the output lever 13. 13c to the second engaging portion 13
Both stoppers 16f and 16g are pushed by the stopper spring 16 after being pushed up to d and passing the slider locking portions 2g and 2h of the slider guide 2f by reducing the projecting dimension of both stoppers 16f and 16g against the stopper spring 16h. The protrusion size of the slide guide 2f is largely restored so that the other side of both the stoppers 16f and 16g is the slider engaging portions 2g and 2h of the slide guide 2f.
It is slid and held to the deadlock operating position H by being locked to the pin 1 by the pin pushing portion 16b.
Hold 1 in the second engaging portion 13d. The pin 11 is loosely inserted into the second engaging portion 13d of the output lever 13 so that the output lever 13 is separated from the free lever 10 into a deadlock state.

When the slider 16 is in the deadlock operating position H, when the motor shaft 15d of the deadlock motor 15 rotates in the reverse direction and the second pinion 17 rotates in the reverse direction, the rack 18 outputs the output lever. 1
Since it is slid in the second direction away from 3,
Move away from deadlock operating position H, and stop spring 16h
Against this, the protrusion size of both stoppers 16f, 16g is reduced to reduce the slider engaging portions 2g, 2h of the slider guide 2f.
After passing through, the stopper spring 16h largely restores the protruding dimensions of both stoppers 16f and 16g, and one side of both stoppers 16f and 16g is locked to the slider locking portions 2g and 2h of the slide guide 2f. Since the pushing portion 16b does not push the pin 11, the output lever 1
3 has a function of holding the pin 11 in the first engaging portion 13c and returning to the deadlock releasing position G, and connecting the output lever 13 to the free lever 10.

Actuator 1 having such a structure
Is connected to the door lock controller via the position switch, and the brush terminals 15b of the deadlock motor 15 are connected to the brush terminals 3b and 3c of the door lock motor 3, respectively.
15c is connected to the door lock controller, sector 8
The door lock side swing arm 21 connected to the outside of the case body 2a is connected to the door lock rod inside the door panel, and the lock knob side swing arm 22 connected to the output lever 13 outside the case body 2a inside the door panel. The case 2 is connected to the lock knob and the case 2 is attached to the door inner panel.

When the occupant is in the vehicle, the door lock is in the unlocked position as shown in FIG.
The sector 8 of the door lock side swing arm 21 is in the unlock position A of the door lock, the free lever 10 is in the unlock position C corresponding to the sector 8, and the pin 11 is the first engaging portion of the output lever 13. Since it is locked at 13c, the output lever 13 is connected to the free lever 10 and is in the unlock position E of the lock knob side swing arm 22. At this time, the slider 16 is in the deadlock releasing position G because the deadlock motor 15 is not energized.

When the inside lock knob is manually switched to the lock position by an occupant from inside the vehicle, the output lever 13 is rotated together with the swing arm 22 on the lock knob side from the unlock position E to the lock position F, so that the output lever 13 is integrated with the output lever 13. By rotating the free lever 10 from the unlocked position C to the locked position D, and by rotating the output lever 13 integrally connected to the free lever 10 by the pin 11 from the unlocked position C to the locked position D. Swing arm 2 on the door lock side via rod 9
In order to rotate the sector 8 together with 1 from the unlock position A of the door lock to the lock position B, the door lock is manually locked.

Further, as shown in FIG. 3, when the door lock is unlocked, the occupant gets out of the vehicle and closes the door, and the door key inserted into the key cylinder of the door moves from the neutral position to the forward direction. When turned to the first key position of the key switch, the brush terminals 3 of the door lock motor 3 are moved from the door lock controller via the position switch.
Since the power source is connected to b and 3c in the forward direction, the motor shaft 3d of the door lock motor 3 rotates in the forward direction to rotate the worm wheel 5 in the forward direction via the worm 4.
As shown in FIG. 6, the sector 8 is rotated together with the door lock side swing arm 21 from the unlock position A to the lock position B so that the sector 8 moves toward the door lock side swing arm 2.
The door lock is locked by rotating together with 1 to the lock position B.

At this time, since the deadlock motor 15 is not energized, the slider 16 is set on both stoppers 1.
One side of 6f and 16g is held at the deadlock releasing position G where the stopper locking portions 2g and 2h are locked, and the pin pressing portion 16b does not press the engaging pin 11 and
Since it is held by the engaging portion 13c of the output lever 13
Is coupled to the free lever 10, and in conjunction with the rotation of the sector 8 to the lock position B, the free lever 10 rotates from the unlock position C to the lock position D via the rod 9 and outputs with this free lever 10. The lever 13 and the swing arm 22 on the lock knob side rotate together with the swing arm 22 from the unlock position E to the lock position F of the inside lock knob to perform a lock operation for switching the inside lock knob to the lock position.

When the sector 8 rotates to the lock position B,
Since the position switch cuts off the connection of the forward power supply to the door lock motor 3, the door lock motor 3 stops the rotation of the motor shaft 3d when the sector 8 is rotated to the lock position B, and the sector 8 is rotated. Is stopped at the lock position B.

When the door key inserted into the key cylinder of the door is turned from the first key position to the second key position of the key switch, as shown in FIG. 5, the door lock controller locks the door. Since the brush terminals 15b and 15c of the deadlock motor 15 are connected to the power source in the positive direction without connecting the power source to the motor 3, the deadlock motor 15 rotates the motor shaft 15d in the positive direction, and the deadlock motor 15 is dead. The slider 16 in the unlocked position G is provided with a stopper pin so that the rack 18 slides in the first direction via the second pinion 17 so that both stoppers 16f and 16g resist the stopper spring 16h and have a small protruding dimension. After passing through the stoppers 2g, 2h, the other side of the stoppers 16f, 16g is stopped by the stopper engaging portions 2g, 2h.
The pin pushing portion 16b pushes the pin 11 on the first engaging portion 13c of the free lever 10 toward the second engaging portion 13d because the pin pushing portion 16b holds the deadlock operating position H. Then, the deadlock operation of loosely inserting the pin 11 supported by the free lever 10 at the lock position D into the second engaging portion 13d of the output lever 13 is performed.

In this state, as shown in FIG. 6, the inside lock knob rod connected to the lock knob side swing arm 22 is operated by an external force from the outside of the door panel to unlock the free lever 10 from the lock position D. By forcibly rotating the sector 8 to the position C, even if the sector 8 is rotated from the lock position B to the unlock position A together with the door lock side swing arm 21, the output lever 13 moves the lock knob side swing arm 22.
In addition, since it is separated from the free lever 10, even if the lock knob side swing arm 22 is rotated to the unlock position E by an external force, the sector 8 cannot be rotated.

The output lever 13 has a lever biasing spring 14
The lever urging spring 14 merely rotates the free lever 10 even if the output lever 13 is rotated together with the lock knob side swing arm 22 by an external force. Since there is no urging force, it will be missed.

When the door key inserted into the key cylinder of the door is turned from the neutral position of the key switch to the third key position in the reverse direction, the door lock is activated in the deadlock operating state shown in FIG. From the controller, each brush terminal 15b, 1 of the deadlock motor 15
Since the reverse direction power source is connected to 5c, the motor shaft 15d of the deadlock motor 15 rotates in the reverse direction, and the slider 16 moves the rack 18 to the second position via the second pinion 17.
Slides in the direction of, and both stoppers 16f and 16g pass through the stopper locking portions 2g and 2h so as to reduce the protruding dimension against the stopper biasing spring 16h, and then one side of both stoppers 16f and 16g Stopper locking part 2g,
Since the deadlock release position G which is locked to 2h is moved and held, the pin pusher portion 16b is connected to the first engagement portion 13c.
Does not press the pin 11 toward the second engaging portion 13d, and holds the pin 11 in the first engaging portion 13c.

At the same time, since the reverse direction power source is connected from the door lock controller to the brush terminals 3b and 3c of the door lock motor 3 via the position switch, the door lock motor 3 has the motor shaft 3d reversed. By rotating and swinging the sector 8 together with the swing arm 21 on the door lock side from the lock position B of the door lock to the unlock position A, the free lever 10 is rotated back from the lock position D to the unlock position C, and by the pin 11. The output lever 13 connected integrally with the free lever 10 is returned and rotated from the locked position F of the inside lock knob to the unlocked position E to return to the unlocked state shown in FIG.

In the slider 16, when the free lever 10 is in the lock position D, the motor shaft 15d of the deadlock motor 15 rotates forward so that the second pinion 17 as a moving means moves the rack 18 in the first direction. When the deadlock releasing position G is slid from the deadlock releasing position G to the deadlock operating position H, the stoppers 16f and 16g are locked to the slider locking portions 2g and 2h of the slider guide 2f at the deadlock operating position H. By
The pin 11 held by the free lever 10 is held by the second engaging portion 13d of the output lever 13, and the pin 11 is held.
Loosely inserted into the second engaging portion 13d of the second lever 13,
The output lever 13 is separated from the free lever 10 and put into a deadlock state so that the sector 8 cannot be moved via the free lever 10 by the power of the swing knob side swing arm 22.
