。[Claims for Utility Model Registration] A motor capable of forward and reverse rotation, a wormshaft rotated by the motor, a wormwheel meshing with the wormshaft, and an output pulley actuated by rotation of the wormwheel, housed in a casing. In the actuator, the wormshaft has a hemispherical protrusion, a bowl-shaped recess that slides into contact with the hemispherical protrusion and prevents it from coming off, and a thrust member that absorbs thrust play of the wormshaft. A wormshaft support structure for an actuator, characterized in that an absorbing elastic member is provided in the casing.
