ものである。The drawings show embodiments of the present invention, in which Fig. 1 is a side view showing the general structural relationship of one example of the antenna expansion/contraction operation mechanism adopted in the present invention, and Fig. 2 shows its rotating gear. FIG. 3 is a cross-sectional view along the axial direction of the rack-like elastic strip, FIG. 4 is a cross-sectional view of the rack-shaped recess, and FIG. 5 is a cross-sectional view of the recess. FIG. 3 is a sectional view of other parts. In these drawings, 1 is a telescopic operation strip, 2 is a rotating gear, 3 is a rack-shaped recess, 4 is a hollow hole, 10 is an antenna base tube, 11 is an antenna element group, and 12 is a winding chamber. be.
