Claims

[Scope of utility model registration request]

A mirror base fixed to the vehicle body, a shaft installed on the mirror base, a mirror assembly rotatably supported on the shaft, a motor built in the mirror assembly, and a clutch mechanism attached to the shaft. In the electric retractable door mirror, the electric retractable door mirror includes a deceleration mechanism disposed between the clutch mechanism and the motor, and an operation switch that is connected to the motor and a power source and performs retracting and returning operations of the mirror assembly. An electrically retractable door mirror characterized in that the mechanism is equipped with a member that can set the amount of rotation due to the inertia of the deceleration mechanism.
