<p>PROBLEM TO BE SOLVED: To improve assemblability and to reduce cost by integrally forming a positioning part for positioning an electric switch and a flexible wiring board with respect to an external barrel with the external barrel. SOLUTION: Recessed parts 4a are formed on both sides (both sides in an optical axis direction) of a part where the electric switch 3 is mounted of the flexible printed wiring board 4. Meanwhile, a supporting plate part made lower by one step from an outer peripheral surface is formed in the attaching device (four spots) of the switch 3 on the peripheral wall of the fixed external barrel 1, and projecting parts (positioning part) 1a are formed to be opposed on both sides in the optical axis direction on the outer surface of the supporting plate part. The electric switch mounted part of the board 4 arranged on the supporting plate part is positioned in a periphery direction with respect to the outer barrel 1 by fitting the recessed part 4a of the board 4 in the projecting part 1a of the external barrel 1. Thus, it is positioned without using a machine screw or the like, and the assemblability is improved with inexpensive constitution.</p> |
