An opening or closing valve 20 is arranged within the cylindrical part 12 while being adjacent to a stepped part 22. The opening or closing valve 20 forms a circular slit SI with a part of a rubber plate 24 being left, a part of it is applied as a supporting part 25 and the inside part of the slit SI is applied as a valve element 26. The peripheral part of the supporting part 25 is formed with a cavity 27 and the supporting part 25 is formed to be thinner than a thickness of the rubber plate 24.
