ABSTRACT:
A device for detecting a position of a moving body is provided in which a position of a moving body such as a window glass can be detected with high accuracy, initial positions can be set without complicated adjustment, such can be realized with a simple structure and at a low cost, and assemblability can be greatly improved. In the device for detecting a position of a moving body, spring claws, which form a clutch mechanism and press a carrier, are formed integrally with a protective plate. A switch portion including a moving contact is provided integrally with a ring gear of the planetary gear group and rotates therewith. The switch portion detects the position of the moving body by on-and-off operation thereof. The spring claws are provided at a side of a planetary gear group (a planetary gear and the carrier) opposite a side at which a cover plate is provided. Accordingly, the protective plate can be installed after the planetary gear group. In a state in which the planetary gear and the carrier are provisionally installed, press-contact force of the spring claws is not applied to the carrier. As a result, the planetary gear and the carrier do not rise and positional deviation does not occur, and therefore, the assemblability can be greatly improved.
