Claims

[Scope of utility model registration request]

(1) A drive cord connected to the antenna element, a drive system that extends and retracts the antenna element via the drive cord by forward and reverse driving of an electric motor, and a drive system that is provided separately from this drive system and operates the antenna element by a drive system. The mainspring spring is wound and stores energy when it is contracted, and adds unwinding force to the driving force of the electric motor when it is extended under an overload. An electric antenna drive device characterized by comprising a spring force adjustment means.

(2) The spring force adjusting means is such that when the antenna element is reduced, the shaft is rotated to wind up the mainspring, and the spring shaft is locked in a predetermined position with a locking member such as a screw or claw. The electric antenna drive device according to scope 1. ′
