The self-sealing member includes a resilient member (82) arranged on a surface of a base material part (81), and an overhanging portion (83) formed on the resilient member and allowed to abut onto the seal area for sealing. The port part includes a seal face (63a) having the seal area formed thereon, and a projecting portion (64) arranged on a region other than the seal area on the seal face.",
