<p>PROBLEM TO BE SOLVED: To provide the simple structure, with which existence of conical coil spring is easily confirmed at the time of inserting a battery and with which battery can be exchanged while saving one's labor and which can improve the convenience in handling. SOLUTION: Structure of a contact of a battery application equipment is formed of a conical coil spring 7 arranged as a battery contact in an opening side of a cylindrical battery housing wall (battery housing section) 2 and a minus contact plate (terminal plate) 6 to be electrically led to the conical coil spring 7. The contact plate 6 is provided with a conical coil spring pinching part 6a, in which an end of the conical coil spring 7 is pinched for support, and this pinching part 6a is arranged in an opening edge of the battery housing wall 2. The conical coil spring 7 is formed of a conical spring main body 10 and a rectangular most outside part (bottom coil body) 11 to be arranged in the bottom of the main body, and the most outside part 11 is fitted to the terminal plate 6 at two positions by energizing it outside from the opening of the battery housing section 2 through the conical coil spring pinching part 6a.</p> |
