Claims

[Scope of utility model registration request]

A stay that supports a mirror, and a case bracket that supports a base end of the stay and allows the stay to be rotatably controlled by a drive motor built in the case, the case bracket comprising: The flange portion is comprised of a flange portion that supports the base end portion of the stay, and a drive portion in which the flange portion is rotatably supported and whose rotation is controlled by the drive motor via a clutch mechanism, and the flange portion includes: A flange plate that directly supports the stay, a first clutch plate that is fixed to the flange plate, a clutch holder that is fixed to the case side and performs a clutching action between the first clutch plate, and the first clutch plate. The clutch mechanism includes a friction material interposed between a plate and a clutch holder, and the clutch mechanism includes a gear connected to the drive motor side and a second clutch connected to an output shaft fixed to the flange side. It consists of a plate, a recess provided on the contact surfaces of the gear and the second clutch plate, and a ball inserted into the recess. By driving the second clutch plate, the second clutch plate is pushed by the ball, opening the space between the first clutch plate and the clutch holder, releasing the frictional force caused by the friction material, and then rotating the stay. An electric stay retractable mirror that moves.
