Abstract
Official abstract text for this publication.
A driving device includes: a neutral switch switches over from ON to OFF when an automatic closing function by a motor is operated and a first cam surface is released from a contact with the neutral switch; and a gear detection switch switches over from ON to OFF when an automatic closing function by the motor is operated and a second cam surface is released from a contact with the gear detection switch, wherein the operation of the automatic closing function by the motor is configured to be initiated by switch-over of a ratchet switch of the door latch unit from OFF to ON and ended by switch-over of the neutral switch from OFF to ON, and the gear detection switch is configured to switch over from OFF to ON by coming into contact with the second cam surface when the automatic releasing function by the motor is operated.
First claim
Opening claim text (preview).
What is claimed is: 1. A driving device of a door latch unit, the driving device comprising: a neutral switch that switches over from ON to OFF, when an automatic closing function by a motor is operated and a first earn surface, is released from a contact with the neutral switch; and a gear detection switch that switches over from, ON to OFF, when aft automatic closing function by the motor is operated and a second cam-surface is released from a contact with the gear detection switch, wherein the operation of the automatic closing function by the motor is configured to be initiated by switch-over of a ratchet switch of the door latch unit from OFF to ON, the operation of the automatic closing function by the motor is configured to be ended by switch-over of the neutral switch from, OFF to ON, the gear detection switch is configured to switch over from OFF to ON by coming into contact with the second cam surface again when the automatic releasing function by the motor Is operated, and the first cam surface and the second cam surface form a continuous surface in a circumferential direction, wherein the second cam surface is set at a height where the second cam surface does not come Into contact with the neutral switch and the second earn surface extends from an end portion of the first cam surface.
