[0017]

Next, the operation will be described. (Operation of FIG. 4 and FIG. 12) Also refer to FIG.
The state in FIG. 4 is an unlocked state. Lock lever 1
4 is in the position shown in FIG. 12, and the contact 42 at the lower end of the lock lever 14 is in contact with the common contact 45 and the contact 43 for the unlock position. Since this state is an unlocked state, when the open lever 52 is opened as shown in FIG.
Is released from the latch 50 and the door is opened.

(Operation of FIGS. 7, 8 and 12) In the state of FIG. 4, when the key is locked, the motor 1 is energized to rotate the drive shaft 2 and rotate via the drive gear 3 and the passive gear 4. By rotating the shaft 5, the worm gear 7 of the rotating shaft 5 is rotated, and the sector worm wheel 9 is swung in the direction b by the arc gear 13 meshing with the worm gear 7 (FIG. 7). When the sector worm wheel 9 swings in the direction b, the right end of the arc-shaped long hole 16 pushes the boss 15, so that the position of the lock lever 14 is displaced from the unlock position to the lock position.

On the other hand, since the gear 8 also rotates, the guide groove 4 is formed by the action of the rack gear 38 meshing with the gear 8 as shown in FIG.
The vertical moving body 35 fitted to the zero is moved up, and the top 34 is also moved up together. However, at first, even if the top 34 moves upward, it does not hit the engaging concave portion 33 well, so that the super lock rod 19 is lifted as shown in FIG. When the swing is completed, the upper engaging portion 41 of the top 34 comes to a position where it completely hits the engaging concave portion 33 and is fitted from below, and at the same time,
Since the distal end engaging portion 27 of the engaging rod 23 which projects by the elasticity of the extension spring 26 engages with the groove 39 of the top 34, the superlock rod 19 does not move due to the engagement of the top 34, and the boss is attached to the superlock rod 19. The lock lever 14 engaged by the lock 15 does not move even if it is turned from the outside to the unlock position by operation of a wire or the like, and is so-called super-locked (or double-locked).

After the super lock shown in FIG. 7, the sector worm wheel 9 is brought to the position shown in FIG. 8 by the action of the center return spring. When the sector worm wheel 9 is brought to the position shown in FIG. 8 by the action of the center return spring, in the structure of the present embodiment, the rotating shaft 5 is rotated back by the arc gear 13 of the sector worm wheel 9, The moving body 35 is moved down,
Since the vertical moving body 35 and the vertical moving body 35 have a separate structure, only the vertical moving body 35 moves down while leaving the frame 34, so that the sector worm wheel 9 can smoothly return to the center. At this time, a gap 46 is formed between the boss 15 and the left end of the arc-shaped long hole 16.

(Operation of FIGS. 9 and 10) FIGS. 9 and 10 show a state of super lock cancellation. Unless you cancel Super Lock, you cannot unlock it. To cancel Super Lock,
When a switch provided at an arbitrary position such as in a vehicle is operated, the motor 1 is energized to rotate the worm gear 7 via the drive shaft 2, the drive gear 3, the passive gear 4, and the rotary shaft 5, and the worm gear 7 The sector worm wheel 9 is slightly rotated in the direction a by the meshing arc gear 13. Preferably, it is about 6 °. Since a gap 46 is formed between the boss 15 and the left end of the arc-shaped long hole 16, when the sector worm wheel 9 rotates by the gap 46, the lock lever 14 is rotated.
Does not move in the locked position, and therefore, the super lock rod 19 does not move, but only the engaging rod 23 has a protrusion 28 on the right end thereof abutting against the left end of the circular arc groove 17, and is about 6 ° of the sector worm wheel 9. Since the protrusion 28 is pushed by the movement in the direction a,
The engaging rod 23 moves in the direction a, and the distal end engaging portion 27 comes out of the groove 39 of the top 34.

When the leading end engaging portion 27 comes out of the groove 39 of the top 34, the top 34 is lowered by the reduction action of the reduction spring 37,
The super lock rod 19 becomes free and is canceled. The figure shows a state in which the sector worm wheel 9 has returned to the center by the center return spring.

(Operation of FIG. 11) This is a case where the lock lever 14 at the lock position of FIG. In the embodiment, the sector worm wheel 9 is swung in the direction of about 32 ° a. When the motor 1 is energized by a key operation, the sector worm wheel 9 is swung through the drive shaft 2, the drive gear 3, the passive gear 4, the rotation shaft 5, and the worm gear 7, and a boss 15 is formed at the left end of the arc-shaped long hole 16. Is moved in the direction a to set the lock lever 14 to the unlock position.
