Claims

[Scope of utility model registration request]

a driving side disk-shaped base having a driving protrusion on one side and being rotatably driven by a motor;
a driven-side disc-shaped base having a driven protrusion on one side opposite to one side of the driven-side disc-shaped base and provided to transfer an antenna expansion/contraction operation wire;
A torsion whose both ends engage the driving protrusion and the driven protrusion with a certain play gap to transmit rotational force between the driving side disc-shaped base and the driven disc-shaped base. The present invention is characterized by comprising a rotation transmission mechanism including a spring and a displacement regulating body that regulates the displacement amount of the torsion spring within a certain range due to the relative movement of the driving protrusion and the driven protrusion. Electric telescopic antenna drive control device.
