Zusammenfassung:	PURPOSE:To improve output and attain compactness and light weight by providing a pressure fluid supply communicating hole in at least one of seal members for sealing both ends of a tubular body formed of a rubber like elastic body provided with reinforcing structure at its outer periphery, and also providing the seal members with hollow fitting members extended opposedly in the axial direction. CONSTITUTION:Braided reinforcing structure 2 is disposed at the periphery of a tubular body 1 formed of rubber or a rubber like elastic body, and a communicating hole 7 communicated with outside is formed at a seal member 4 out of seal members 3, 4 for sealing both ends of the tubular body 1. Fitting members 10, 11 are further formed at the seal members 3, 4, and O-rings 12 are fitted between the fitting members 10, 11 to maintain airtightness. Compactness and light weight can be thereby attained, the pressure fluid quantity used by a hollow space can be reduced, and effective function can be added.
