Claims

[Claims for Utility Model Registration] 1. An operating shaft that is driven in the front-rear direction of the mirror by the rotation of a terminal gear element of a reduction gear mechanism driven by an electric means is provided in the housing, and the tip of this operating shaft is connected to the mirror. A mirror drive device that is swingably attached to a mirror holder provided on the back surface of the mirror to freely adjust the inclination angle of the mirror, wherein a concave spherical socket is integrally provided at the center of rotation of the terminal gear element, On the other hand, an electric rearview mirror driving device characterized in that a spherical pivot that fits into the concave spherical socket is provided at the rear end of the operating shaft, and both are fixed so as to be tiltable. 2. The drive device according to claim 1, wherein the spherical pivot has a small protrusion formed on its peripheral surface, and a rotation stopper groove that engages with the small protrusion is formed in the concave spherical socket. 3. Utility model registration claim 1, in which a concave spherical socket and a terminal gear element are formed separately, the socket is fitted around a spherical pivot, and the socket and terminal gear element are caulked together. The drive device described in Section 1. 4. The drive device according to claim 1, wherein the operating shaft is comprised of a threaded rod having a threaded portion formed on its circumferential surface, and an adjustment nut fitted to engage with the threaded portion. 5. The drive device according to claim 1, wherein the terminal gear element is a worm wheel that meshes with a worm.
