PROBLEM TO BE SOLVED: To obtain an equipment in which an operation easiness and an equipment portability are improved and traffic in enabled in a high sensitivity state, by energizing an antenna to be extended outside of the equipment, locking the antenna at the time of containing and releasing engagement by means of at least one operation at extending. SOLUTION: Since a hole 21a of an engaging member 21 is placed at an eccentric position as with respect to the center of a whip antenna 8, an edge part 21b of the hole 21a is engaged with a small diameter part 8d of the whip antenna 8 for the small diameter part 8d of the whip antenna 8 and the hole 21a of the engaging member 21. A diameter D in the hole 21a of the engaging member 21 is larger than the diameter d of the large diameter part 8c of the whip antenna 8. When the engaging member 21 is moved to a non-engaging position, the axial center of the whip antenna 8 and the center of the hole 21a of the engaging member 21 coincide with the axial center of the whip antenna 8, an engaging image is released, and the whip antenna 8 is put-through the hole 31a so as to be protrude to the outside. When the whip antenna 8 is contained, it is stopped in a state with only an upper columnar body 8a being exposed. |
