Claims

[Scope of utility model registration request]

(1) In addition to arranging an inner pole group that can be expanded and contracted in multiple stages within the outer pipe, the tip of the drive cord is connected to the smallest diameter pole of the inner pole group through the inside of the inner pole group, and the drive cord is extended and pulled back by a motor drive. In the electrically-operated telescopic antenna device for telescopically operating the inner pole group, an elastic device is incorporated in the outer tube to constantly press and bias the inner pole group to a position where a maximum diameter pole tip of the inner pole group protrudes from the outer tube. An antenna device characterized by:

(2) The elastic device is formed of a coil spring, and this coil spring is connected to a cylindrical auxiliary guide fixed to the base end of the outer tube, and the base end is loosely fitted into this auxiliary guide, and the drive cord is inside. Claim 1 of the utility model registration claim characterized in that the pole is interposed between a penetrating cylindrical slide guide, and the tip of the slide guide presses and urges the base end of the largest diameter pole. Electric telescopic antenna device.

(3) Utility model registration claim 1 or 2, characterized in that the distal end surface of the slide guide is provided with a recess into which the base end of the largest diameter pole is inserted for alignment.
The electric telescoping antenna device described in .
