PURPOSE:To simply accommodate batteries and surely prevent coming off of the accommodated batteries. CONSTITUTION:A battery 17 is accommodated in a compartment 16 in such a way that its anode 14 is pressed against a coil spring 45 of an electrode 20, then its cathode 48 is pressed against a bottom plate 22 so as to get over a coming-off prevention plate 41. Since the battery 17 is pressed against an electrode 21 by elasticity of the coil spring 45, the cathode 48 is surely brought into contact with a projecting part 36. Since the coming-off prevention plate 41 prevents coming off of the battery, batteries 17 are accommodated in order in the compartment 16. Since the coming-off prevention plate 41 is extended from the projecting part 36 toward the compartment 16, contact of the anode 49 to the projecting part 36 is prevented even if the battery 17 is accommodated with its polarity opposite. |
