Claims

[Scope of utility model registration request]

(1) A board fixed in the mirror housing that rotatably supports approximately the center of the rear surface of the mirror holder that holds the mirror, and also supports the support part of the mirror holder on either the upper or lower side and on the left or right side. One end of an operating rod that pushes and pulls the mirror holder is connected, and a male screw provided on the other side of the operating rod is removably engaged with a screw provided on a drive gear driven by a motor. In a mirror drive device that tilts and adjusts the angle of the mirror by pushing and pulling an operating rod, a thin-walled cylindrical portion is integrally formed at the rotation center of the drive gear, and a tip circumference of the thin-walled cylindrical portion is formed. In addition to providing a plurality of protrusions for female screws on the surface to engage with the male screws of the operating rod,
A mirror driving device characterized in that a plurality of cut grooves having a constant length are provided in the axial direction from the tip of the thin-walled cylindrical portion to enable deflection in the radial direction.

(2) In the device described in claim (1) of the utility model registration, the thin-walled cylindrical portion is provided with an annular groove between the shaft hole of the drive gear and the gear portion, and the axial length of the thin-walled cylindrical portion is A mirror driving device characterized in that the length includes a part of the tooth width length of a gear portion.
