摘要： A liquid-inlet cap (13) is installed in a liquid inlet (11) provided in a battery casing, the liquid-inlet cap (13) having a ventilating hole (12) for expelling a gas from the inside of a battery to the outside of the battery. A control valve section (21) is installed inside a cylindrical body (20) of the liquid-inlet cap (13) separately from the cylindrical body (20) and responds to the internal pressure of the battery to form a ventilating passage from a vent hole (22) provided on one end to a ventilating opening (28) provided on the other end.
