Title: GAS-PERMEABLE UNIT
Abstract:
This gas-permeable unit is provided with: an explosion-proof valve 10 which permits gas to flow from the inside of a housing 120 to the outside of the housing 120 when internal pressure within the housing 120 reaches a pressure higher than external pressure outside the housing 120 by a value greater than or equal to a predetermined value, and which is capable of returning so as to block the flow of the gas from the inside of the housing 120 to the outside of the housing 120; and a gas-permeable membrane 40 which permits gas to flow between the inside of the housing 120 and the outside of the housing 120 even when the difference between the internal pressure and the external pressure is less than the predetermined value.
