Claims (1)

[Claim for Utility Model Registration] A mirror body is tiltably supported with respect to a mirror drive unit housing, and one end of a female threaded cylindrical advancement/retraction rod provided in the drive unit is connected to the mirror body by a ball joint. , and an O-ring is interposed at the point where the cylindrical advance/retreat rod passes through the mirror drive unit housing to maintain airtightness and watertightness within the mirror drive unit housing, and the mirror drive unit housing is housed within the drive unit housing. An electric remote control mirror in which a male threaded member driven by a motor driven through a reduction gear group is screwed into a female thread provided on the inner periphery of the cylindrical advancement/retraction rod, comprising: a. a final stage receiver of the reduction gear group; The gear and the male threaded member are constructed separately, and a removable engagement portion is provided for transmitting rotational force to each member, and the male thread is flexible by dividing the thread in the circumferential direction. The structure is such that the elasticity of the arm presses the thread of the male screw against the female screw on the inner circumference of the cylindrical retractable rod, and the elastic deformation of the arm presses the thread of the male screw against the female screw on the inner circumference of the cylindrical retractable rod. (b) A cylindrical member that fits loosely into the forward/backward lever is configured at the location where the forward/backward lever passes through the mirror drive unit housing; A cylindrical member is integrally connected to the mirror drive unit housing, and c. A ring groove is provided near the opposite end of the advancing/retracting rod to the side connected to the mirror body, and an O-ring is inserted into this ring groove. An electric remote control mirror, characterized in that the O-ring is fitted externally so that the outer periphery of the O-ring slides against the inner periphery of the cylindrical member.
