Since the electrolytic solution is foamed (hereinafter referred to as gassing), the splash of the electrolytic solution directly hits the safety valve 4 and the valve cylinder 5 and is pushed out together with the gas from between the safety valve 4 and the valve cylinder 5. . Further, the splash-proof structure surrounding the lower surface of the exhaust port and the surrounding four surfaces described in the conventional technique can prevent the splashing of the electrolytic solution, but since the structure is complicated, the number of parts is increased and the productivity of the assembly work is increased. Had the problem of being inferior.
