Beschreibung
Zusammenfassung:	An actuator includes a motor having a rotation shaft, and an output shaft disposed coaxially to the rotation shaft. A rotation shaft side gear is provided so as to be rotatable as a unit with the rotation shaft, and an output shaft side gear is provided so as to be rotatable as a unit with the output shaft. An intermediate gear configuration body is provided between the rotation shaft side gear and the output shaft side gear. The intermediate gear configuration body includes a first intermediate gear that meshes with the rotation shaft side gear, and a second intermediate gear that is provided so as to be rotatable as a unit with the first intermediate gear and that meshes with the rotation shaft side gear. A detected portion is provided at an end portion of the intermediate gear configuration body and detects a rotation speed of the intermediate gear configuration body. A detecting portion detects the detected portion. The rotation shaft side gear, the first intermediate gear, the second intermediate gear, and the output shaft side gear are housed inside a gear housing that is disposed at one side in an axial direction of the motor, and the detecting portion is disposed outside of the gear housing.
