FIG. 2 is a part of the door on which the unlocking actuator is attached. 3 is a cross-sectional view taken along line 3-3 in FIG. 2, FIG. 4 is a view taken in the direction of arrow 4 in FIG. 3 with the inner panel of the door omitted, and FIG. 6 is a view of the unlocking actuator with the cover plate removed as seen from the same direction as FIG. 5, FIG. 7 is a sectional view taken along line 7-7 in FIG. 3, and FIG. 8 is an electric circuit including an electric motor. 9 is a sectional view taken along line 9-9 in FIG. 6, FIG. 10 is a sectional view taken along arrow 10 in FIG. 9, and FIG. 11 is a sectional view taken along line 11-11 in FIG.

  First, in FIG. 1, the door D is slidable back and forth between a closed position on the front side (left side in FIG. 1) and an open position on the rear side (right side in FIG. 1). It is attached to the right side of the vehicle body and is automatically opened and closed by an electric door opening and closing device (not shown).

  The rear portion of the door D is provided with a rear latch mechanism 11 for engaging the door D with the vehicle body in the closed state and maintaining the closed state. The rear latch mechanism 11 has the door D in a completely closed state. For this purpose, a lock actuator 12 is attached. Further, a front latch mechanism 13 is provided at the front portion of the door D to engage the door D with the vehicle body in the closed state and maintain the closed state. An outside handle mechanism 14 that allows a handle to be operated outside the door D is provided above the front latch mechanism 13 and at the upper front side of the door D. The outside handle mechanism 14 has a rear side of the door D behind the outside handle mechanism 14. In the upper part, a remote control mechanism 16 having an inside handle 15 disposed inside the right door DR is provided, and the vehicle body with the door D opened in the front portion of the door D below the front latch mechanism 13. A lower latch mechanism 17 that engages the side and maintains an open state is provided, and the rear latch mechanism 11, the front latch mechanism 13, and the lower latch mechanism are provided on the door D behind the front latch mechanism 13. An unlocking actuator 18 that can apply power on the unlocking side to 17 is attached.

  The operating force exerted by the unlocking actuator 18 is transmitted to the front latch mechanism 13 via the rod 19. The operating force accompanying the operation of the outside handle mechanism 14 is transmitted to the front latch mechanism 13 via the first transmission cable 21, and the front latch mechanism 13 is transmitted from the unlocking actuator 18. The second transmission cable 22 is configured so that the unlocking actuating actuator 18 and the outside handle mechanism 14 do not interfere with each other between the actuating force applied and the actuating force transmitted from the outside handle mechanism 14. The activating force for unlocking which is converted from the second transmission cable 22 to the remote control mechanism 16 is converted into the rear traction force via the third, fourth and fifth transmission cables 23, 24 and 25. 11 is transmitted to the front latch mechanism 13 and the lower latch mechanism 17. Further, the remote control mechanism 16 can directly transmit the unlocking operation force accompanying the operation of the inside handle 15 to the third, fourth and fifth transmission cables 23, 24, 25.

  Thus, when the switch operation for opening the door D is performed at the driver's seat in the closed state of the door D, the unlocking operation actuator 18 is operated, and the unlocking operation actuator 18 is forwarded through the rod 19 to the front. The power transmitted to the part latch mechanism 13 is transmitted to the remote control mechanism 16 via the second transmission cable 22, and is used for unlocking operation from the remote control mechanism 16 via the third and fourth transmission cables 23 and 24. Power is transmitted to the rear latch mechanism 11 and the front latch mechanism 13. As a result, the rear and front latch mechanisms 11 and 13 are unlocked, and the door D is automatically opened by the electric door opening and closing device. When the door D is fully opened, the lower latch mechanism 17 is locked. By doing so, the fully open state of the door D is maintained.

  In addition, when the switch operation for closing the door D is performed at the driver's seat in the opened state of the door D, the unlocking operation actuator 18 is activated, and the front latch is moved from the unlocking operation actuator 18 through the rod 19. The power transmitted to the mechanism 13 is transmitted to the remote control mechanism 16 through the second transmission cable 22, and the power for unlocking operation from the remote control mechanism 16 to the lower latch mechanism 17 through the fifth transmission cable 25. Communicated. As a result, the lower latch mechanism 17 is unlocked, and the door D is automatically closed by the electric door opening and closing device. At this time, the rear latch mechanism 11 is locked so as to be fully closed when the operation of the lock actuator 12 is started from the half-door state of the door D, and the front latch mechanism 13 is locked accordingly. By operating, the fully closed state of the door D is maintained.

  On the other hand, when the inside handle 15 is opened in the closed state of the door D, the unlocking actuator 18 is activated in response to the opening operation, and the front latch mechanism 13, the remote control mechanism 16, the rear latch mechanism 11, and the lock The release actuating actuator 18 operates in the same manner as the switch operation for opening the door D at the driver's seat, and the door D is automatically opened by the electric door opening / closing device. When the lower latch mechanism 17 is locked in the fully opened state, the fully open state of the door D is maintained.

  When the inside handle 15 is closed in the opened state of the door D, the unlocking actuator 18 is operated according to the closing operation, and the front latch mechanism 13, the remote control mechanism 16 and the lower latch mechanism 17 are operated. The door D is automatically closed by the electric door opening and closing device, and the door D is locked from the half-door state. When the operation of the actuator 12 is started, the rear latch mechanism 11 is locked so as to be fully closed, and the front latch mechanism 13 is locked accordingly, so that the door D is fully closed. The

  When the handle operation of the outside handle mechanism 14 is performed, similarly to the operation of the inside handle 15, the unlocking actuator 18, the front latch mechanism 13, the remote control mechanism 16, the rear latch mechanism 11 and the lower latch are operated. The mechanism 17 is activated.

  The remote control mechanism 16 includes a lock knob 26 that operates between an upper unlock position and a lower lock position according to a manual operation, and a lock switching actuator 27 that operates the lock knob 26 according to an operation at the driver's seat.
