(Action of movement of each part) The wire 1 is manually operated by the key cylinder H or the sill knob E.
The lock lever 4 is rotated via the wire 5a or the wire 19 or the lock / unlock actuator 3 is energized to rotate the lock lever 4 by the output lever 17 and the right protrusion 14
When is rotated upward, the lock lever 4 is brought to the unlock position shown in FIG. When the lock lever 4 is in the unlocked position, the pin 20 of the lock link 21 whose upper end is axially locked to the right protruding piece 14 moves upward in the elongated hole 48 of the lower arm 45 of the ratchet lever 8 to cause the lock. Pin 20 of link 21
Fits perfectly into the engaging groove 43 (FIG. 9) of the outer open lever 6. As a result, the outer open lever 6 is connected to the ratchet lever 8 via the pin 20 engaged with both the engaging groove 43 and the elongated hole 48, and the ratchet lever 8 is also interlocked with the rotation of the outer open lever 6. Rotate. When the ratchet lever 8 rotates, the rear latch device C, which is connected to the engagement hole 46 of the right arm 44 of the ratchet lever 8 by the wire 47, opens the door by releasing the ratchet from the latch. Like the rear latch device C, the front latch device B is also connected to the ratchet lever 8 at its lower end with a wire reaching the front latch device B as shown in FIG.

The child lock operating lever I is manually operated to move the central protruding piece 24 of the child lock lever 5 via the operating rod 31 so that the convex portion 27 of the left protruding piece 22 is engaged with the concave portion 25 of the metal plate 1. When combined, the resin lever 30 whose lower end is axially fixed to the right protruding piece 23 of the child lock lever 5 moves down, and the projection 29 at the upper end moves down in the radial elongated hole 34 of the outer open lever 6.

In this state, the inner open lever 7 and the outer open lever 6 are integrally rotated by the protrusion 29 engaged with both the non-idle vibration groove 55a and the radial elongated hole 34. Therefore, when the inner door opening handle G is opened, the inner open lever 7 which is in the fixed position by the spring 5a.
Is rotated clockwise in FIG. 3 via the wire 53,
The outer open lever 6 rotates counterclockwise in FIG. 2, and the ratchet lever 8 also rotates in conjunction with the pin 20 to open the door.

Further, in FIG. 2, when the actuator 9 for automatic door opening is energized (by operating a button in the vehicle) to move the output lever 41 and rotate the outer open lever 6 counterclockwise via the rod 42. Similarly, the ratchet of the rear latch device C can be disengaged from the latch.

After the door opening operation, the slide door is slid to a completely open position by a separately known automatic slide door opening device.

When switching to the child lock state, the child lock operating lever I is manually operated to rotate the child lock lever 5 clockwise in FIG. 3 via the operating rod 31. Then, the protrusion 27 of the left protruding piece 22 of the child lock lever 5 becomes the recess 2 of the metal plate 1.
6, the right side protruding piece 23 moves upward, and the lower end of the right side protruding piece 23 is axially fixed to the lower end of the resin lever 30.
Moves upward in the radial elongated hole 34 of the outer open lever 6 and the window hole 54 of the inner open lever 7,
4 is displaced to a position facing the empty vibration groove 55, and the child lock state is established. In this state, the inner open lever 7 is opened by the operation of opening the inner door handle G as shown in FIG.
Even if it is rotated clockwise, the idling groove 55 does not engage with the protrusion 29, so that the rotation of the inner open lever 7 is not transmitted to the outer open lever 6 and the outer open lever 6 does not rotate. Therefore, regardless of the position of the lock lever 4, in the child lock state, the door cannot be opened by the door opening operation of the inner handle G.

When switching from the unlocked state to the locked state, the lock lever 4 is rotated clockwise in FIG. 2 via the wire 15a or the wire 19 by the manual operation of the key cylinder H or the sill knob E, or the locking / unlocking actuator 3 is operated. By energizing, the lock lever 4 is rotated clockwise by the output lever 17, and the right protruding piece 14 is rotated downward. Then, the pin 20 of the lock link 21 that is axially fixed to the right protruding piece 14 moves downward and moves to the outer open lever 6
When the pin 20 and the outer open lever 6 are released from the engaging groove 43 of FIG. In this state, even if the outer open lever 6 is rotated by various means, the pin 20 cannot be moved. Therefore, the ratchet lever 8 also does not rotate, and therefore the door cannot be opened.
