CONSTITUTION:When a rotary shaft 6 is made to slide in a long groove 7, coupling between a retaining part 10 and a retaining claw 11 is released. Then a battery lid 3, which has been shut withstanding the force energized by a spring 9, is opened, and a battery 8 is pushed out by the spring force. After the battery is replaced, the battery lid 3 is revolved; a battery is pressed down withstanding the spring force; the retaining part 10 and the holding claw 11 are engaged with each other; hence the lid is shut. Thereby, a series of operation of battery replacement and lid shutting is enabled by one-handed operation. By this set-up, the coupling of battery lid is strengthened by the effect of spring force cf the battery pushing spring; when the battery is not loaded, the spring force is not applied, so that the opening and shutting of the lid is freely enabled, and handling is made easy.
