Patent ID: 7168816

Claim:
A vehicle door minor device comprising: a mirror device body that comprises a mirror that reflects light and which is rotatable between a folded position where the reflective surface of the mirror faces a side towards the inside of a cab in the vehicle's widthwise direction and an expanded position where the reflective surface faces a direction inclined at a preset angle toward the approximate fore-aft direction of the vehicle or the approximate up-down direction of the vehicle; a stay that is attached at a door panel or a vehicle body in the vicinity of the door panel; a stand comprising a shaft with a preset axial direction, the stand being attached to the stay; a motor actuator that is mechanically joined to the minor device body and which comprises a housing that is rotatably supported by the shaft, the motor actuator rotating around the shaft due to the driving force of a motor provided in the interior of the housing; a ring component provided at the inner side of a circular groove formed coaxially with the axial direction of the shaft at the bottom portion of the housing; a ring-shaped restricting component that is assembled to the stand or the stay coaxially with the shaft and which is inserted into the inner side of the circular groove in a state where the housing is supported by the shaft, the ring-shaped restricting component being opposite the ring component while impeding the ring component at a first preset turning position around the shaft and restricting the turning of the housing in one direction around the shaft; a restricting unit that impedes the housing at a second preset turning position around the shalt that differs from the first turning position and which restricts turning of the housing in the other direction around the shaft; and wherein said ring-shaped restricting component includes positioning portions which interfit with fitting portions of said stand or stay to prevent rotation of said ring-shaped restricting component relative to said stand or stay such that a same ring-shaped restricting component may be assembled on to the stands or stays of other vehicle door mirror devices having said fitting portions at different angular positions around said shaft.
