Abstract
In a drive unit for an electric remote control mirror, a pair of screw rods for slanting the mirror around horizontal and vertical axes is disposed movably forwardly and backwardly within the drive casing. Within the drive casing, there is disposed a pair of drive motors, of which the rotations are transmitted through a reduction gear group to a pair of rotation members, of which the rotations are converted into forward and backward movements of the pair of screw rods. Each of the rotation members is composed of a shaft having a pair of arm members with a screw thread which is in mesh with a screw thread formed on the inner circumference of the screw rod, a hollow cylindrical rotation body having a gear in mesh with the reduction gear group and a space in which the screw rod is placed, and a plurality of connection members extending radially and which provides a connection between the base of the shaft and the lower end of the rotation body, each of the connection members being formed relatively thin so that when the shaft is exposed to a force from the screw rod, the connection member is resiliently deformable. When each screw rod is moved forwardly or backwardly, the shaft is exposed to a force from the screw rod, but since the plural connection members are resiliently deformed, the shaft can be slanted axially so that each screw rod can positively follow up with the pivoting of the mirror.
