Claims

[Scope of utility model registration request]

In a vehicle mirror in which a mirror housing is rotatably supported by a stay pipe, a drive motor fixed to the mirror housing, a first stage reduction gear fixed to the rotation shaft of the drive motor, and a first stage reduction gear meshed with the drive motor are fixed to the rotation shaft of the drive motor. A second-stage reduction gear with bevel teeth fixed concentrically with the first-stage reduction receiving gear, a second-stage reduction gear with bevel teeth meshing therewith, and a second-stage reduction gear concentrically relative to the second-stage reduction receiving gear. a third-stage reduction gear rotatably supported by a shaft; a constant torque friction transmission means interposed between the second-stage reduction receiving gear and the third-stage reduction gear; and a third-stage reduction gear. A third stage reduction gear that meshes with the gear, a worm original gear that is concentrically fixed to the third stage reduction gear, and a worm gear that meshes with this are provided, and the worm gear is A vehicular mirror drive device, characterized in that the stay pipe is slidably fitted on the outside of the stay pipe, and the stay pipe and a worm receiving gear are connected via a constant torque friction transmission means.
