Claims

[Claim for Utility Model Registration] A visor rotation shaft is provided protruding from a stay fixed to the outer surface of the door, and a rotation hole of a visor that supports a mirror in a tiltable manner is fitted into the rotation shaft, and the visor is rotated around the rotation shaft. In the electric folding door mirror which can be rotated at least in the rearward direction by a motor, a drive unit case housing a motor and a reduction gear train driven by the motor is fixed in the visor, and the drive unit case is fixed in the visor. The motor is installed horizontally within the case, and a worm gear is fixed to the output shaft of the motor, and rotational force is transmitted from the worm wheel to the shaft of the worm wheel that meshes with the worm gear and to a vertical shaft parallel to the shaft. A plurality of reduction gears are installed in mesh with each other on the left and right, and a gear that meshes with the final gear of the reduction gears is fitted into the visor rotating shaft located on the lower side of the drive unit case. A base clutch having a moderation engagement portion formed on the end face and having a moderation engagement portion on the end face that engages with the moderation engagement portion is fitted to the stay rotating shaft so as to be movable up and down but not rotatable, and the base clutch and the visor are connected to each other. An electric visor storage device for a door mirror, characterized in that a spring is compressed between the visor and the stay to bias a moderation engagement portion formed on a rotating sliding surface between the visor and the stay.
