たことを特徴とするドアミラー構造。A rotating base is rotatably supported by a pivot shaft fixed to the mirror base, a mirror housing is attached to the rotating base, and a drive motor and a reducer for rotating the rotating base are rotated. mounted on the base, and
In the door mirror, the door mirror is provided with a gear means for transmitting the output of the drive motor to the reduction gear, and in which an output gear fixed to the output shaft of the reduction gear and a receiving gear attached to the pivot shaft are meshed. The gear is attached to the pivot shaft via a clutch means, and the clutch means has a structure in which a receiving gear is used as a drive plate, and a friction plate is interposed between the receiving gear and the driven plate. , the protrusion provided on the driven plate surface is fitted into the hole provided on the friction plate surface to lock the relative rotation of both members, and the output of the drive motor is connected to a reducer. The gear chamber of the gear means for transmitting power has a structure in which a lid member is attached to a recess formed on the bottom surface of the rotating base, and a protrusion is provided around the top surface of the lid member to prevent oil from flowing out. and at least one of an output gear and a receiving gear that transmits the output of the speed reducer to the pivot shaft covers the outer periphery of the gear so that the electric wire of the drive motor does not come into sliding contact with the gear. A cylindrical cover is provided, and a cover is provided to cover the periphery and above of the drive motor and reducer, and the cover is attached to a rotating base, and a frame-shaped support member is integrated with the cover. A door mirror structure characterized in that a mirror housing is attached to the above-mentioned supporting member in series with each other.
