A wire harness lead-out structure includes a body that includes a containing portion for receiving a wire harness and a corrugated tube covering the wire harness, a lid that is attached to the body to close an upper opening of the body, two completely-fixing ribs that are formed on the body and the lid respectively to be engaged in grooves of the corrugated tube to prevent a movement of the corrugated tube in an axial direction of the corrugated tube, and a provisionally-fixing rib that is formed in a single line on the opposed side walls of the body to be engaged in a single groove of the corrugated tube, and is disposed between the two completely-fixing ribs. The wire harness lead-out structure length required for provisionally fixing a corrugated tube can be reduced and a compact design can be achieved.

Abstract:
A device includes a latch of a door and rotates while engaging with a striker of a vehicle body; a pawl which is rotatable between a latched position to restrict a rotation of the latch and a unlatched position to permit the rotation of the latch; a motor; a release power transmitting unit which transmits a rotational power of the motor to the pawl and rotates the pawl from the latched position to the unlatched position. The device further includes a motor-side rotation board, a relay rotation board, and a pawl-side rotation board, which are connected to be integrally rotatable. The relay rotation board become movable to a power shutoff position by pressing operation though an operating hole formed in a door. In the power shutoff position, connecting between the three boards is released, and the motor-side rotation board and the pawl-side rotation board become individually rotatable.
