Abstract
A rotation detecting sensor is situated on the inside of a sleeve, so that the sensor detects a detected member, such as an input shaft and the like for an automatic transmission, from the inside of the sleeve. A hub projected toward inside a case is constituted, a sleeve enclosing the hub is fixed on the rotating shaft, the rotation detecting sensor is installed on the hub so that the sensor faces a detected member constituted on the inner surface of the sleeve. By this, the rotating shaft such as the input shaft and the like rotates with being supported by the hub of the case, and the sleeve fixed on the rotating shaft rotates together. The detected member is detected by the rotation detecting sensor placed at the hub.
