Claims

[Scope of utility model registration request]

A mirror body is tiltably supported with respect to the mirror drive unit housing, and one end of a retractable rod provided on the drive unit is connected to the mirror body via a ball joint, and the retractable rod is screwed. In the electric remote control mirror, which is a provided member and configured to be reciprocated by a motor housed in the drive unit via a receiving gear and a drive screw, the advance/retreat rod has a cylindrical shape provided with a female thread. , the drive screw is configured as a tubular male thread and provided with an axial cut;
The drive screw and the receiving gear are fitted together to prevent relative rotation, and a threaded tube support shaft is implanted and fixed to the inner wall of the mirror drive housing. A tubular male threaded member is rotatably fitted onto the threaded pipe support shaft, and further, a rotation prevention protrusion is provided on the reciprocating rod, and a rotation prevention rib is fixed to the drive unit housing, and this rib is An electric remote control mirror characterized in that a rotation preventing protrusion is configured to allow sliding in the axial direction of an advancing/retracting rod while locking rotation about the axis.
