Abstract
An antenna device is provided that is preferably used for various wireless devices such as television receivers and the like. An antenna rod can be stopped at a predetermined angle position via a hinge mechanism. The antenna device includes a hinge mechanism by which a biasing force of a coil spring stored in an antenna base causes an upper end of a circular-cylindrical projection of an abutting member to be abutted with an end face of a projection section of an intermediate member fixed to a lower part or antenna rod, thereby stopping the antenna rod at a predetermined angle position. When the antenna rod is moved to a different angle position, the abutting member has a biased movement in the downward direction. This can suppress the wear of the circular-cylindrical projection.
