置。 A disc-shaped main drive side base body that rotates when given a driving force from the motor side, a disc-shaped driven base body that is arranged concentrically with the main drive side base unit and transmits the received rotational force to the antenna side, and the main drive side base body. and the driven base, one end engages with the main protrusion of the driven base, the other end engages with the subordinate protrusion of the driven base, and transmits the rotational force of the driven base to the driven base. a stopper loaded in an annular spring insertion region existing between the driving side base body and the driven side base body so as to limit the amount of elastic deformation of the coil spring to a set value or less; ,
In order to prevent the main protrusion from engaging in positions other than the normal position, the length of the main protrusion in the circumferential direction is longer than the maximum gap length obtained between both ends of the coil spring and both ends of the stopper. An electric telescopic antenna drive device characterized by a long length.
