PURPOSE: To attain the expansion and accommodation of an antenna with simple operation by devising the titled antenna such that the metallic strip is in standstill vertically at the position when the antenna metallic strip is led out of the casing by a finger and the finger is detached at a desired length to operate the antenna and the metallic strip is restored, and accommodated momentarily into the casing when the pressure provision mechanism is released.

CONSTITUTION: The antenna metallic strip 6 not in use is wound and accommodated into the casing 1 by a tensile force of a spiral spring member 4 and in using the antenna, a tip 6' of the metallic strip 6 is hooked by a finger and led out of the casing 1. In such a case, since the tensile force of the spring member 4 is energized to the metallic strip 6, a prescribed pressure is added so that the metallic strip 6 is restored to the original position even when the finger is detached. The metallic strip 6 is formed of convex to prevent folding or distortion, then the metallic strip 6 comes to a stop at the position even when the finger is detached at a desired position vertically. In stopping the use, when the pressure provision mechanism 7 is released then the metallic strip 6 is restored naturally into the casing by the tensile force of the spring member 4.
