통상이며 외주면으로부터 외측으로 돌출된 외측 돌출부(22)를 갖는 보유 지지 부재(20)와, 보유 지지 부재(20)에 있어서의 중심선 방향의 한쪽의 단부를 덮도록 설치되고, 액체 및 고체가 보유 지지 부재(20)의 외측으로부터 보유 지지 부재(20)의 내측으로 침입하는 것을 저지함과 함께 기체가 내측과 외측 사이에서 유통하는 것을 허용하는 통기막(10)과, 보유 지지 부재(20)의 주위에 설치되고, 측벽부(31)와, 측벽부(31)에 있어서의 중심선 방향의 한쪽의 단부를 막는 정상부(33)와, 측벽부(31)의 내주면으로부터 내측으로 돌출됨과 함께 통기막(10)과 정상부(33) 사이에 기체가 유통하는 통기로 R을 형성하도록 보유 지지 부재(20)의 외측 돌출부(22)와 접촉하는 내측 돌출부(32)를 갖는 커버 부재(30)를 구비한다. The ventilation member 1 includes: a holding member 20 of a cylindrical shape, the holding member 20 including an outer projection portion 22 projecting outward from an outer circumferential surface of the holding member 20; a ventilation film 10 mounted so as to cover one end of the holding member 20 in a centerline direction, the ventilation film 10 preventing a liquid and a solid from entering an inside of the holding member 20 from an outside of the holding member 20, the ventilation film 10 permitting a flow of gas between the inside and the outside; and a cover member 30 provided around the holding member 20, the cover member 30 including a side wall portion 31, a top portion 33, and an inner projection portion 32, the top portion 33 closing one end of the side wall portion 31 in the centerline direction, the inner projection portion 32 projecting inward from an inner circumferential surface of the side wall portion 31 and contacting the outer projection portion 22 of the holding member 20 so as to form a ventilation passage R between the ventilation film 10 and the top portion 33, the ventilation passage R allowing gas to flow therethrough.
