Claims

[Scope of Claim for Utility Model Registration] Consisting of an upper case and a lower case that house a motor and a reduction gear train, the upper case and the lower case are provided with a latching mechanism so that they can be attached to and detached from each other, and inside both cases. A noise dampening mechanism of a grease container is formed in a region where a worm gear attached to the shaft of the motor is located, and a worm wheel that meshes with the worm gear and a region through which the motor shaft passes are cut out, and a noise damping mechanism of a grease container is formed on the lower surface of the pinion gear of the gear train. A conductive sliding plate with a partially cut out part is attached to the plate, and two contacts whose tips are separated by an appropriate distance are placed in contact with the sliding plate, and at least one of the contacts is connected to the sliding plate. A reduction gear unit structure for a worm gear device, which is installed in the case to constitute a switching mechanism so that as the sliding plate rotates, the notch contacts the sliding plate at a circle drawn by the sliding plate.
