ABSTRACT:
A motor driven antenna for vehicles including an antenna element, an antenna housing tube which stores the antenna element and is fixed to a mounting hole of the vehicle body, a motor mechanism mounted on the base of the antenna housing tube, which retracts and extends the antenna element housed in the antenna housing tube, and a coupling mechanism for coupling the casing for the motor mechanism to the antenna housing tube. The coupling mechanism includes a first vibration absorber provided between a housing tube holding section of the motor mechanism casing and the base portion of the antenna housing tube, a second vibration absorber which fits on the antenna housing tube at a position away from the first vibration absorber a specified distance toward the tip of the end of the antenna housing tube and a coupling member for connecting the second vibration absorber and the motor mechanism casing so that the coupling member holds the second vibration absorber therein.
