Claims

[Scope of utility model registration request]

(1) An elastic pipe made of an elastic material such as rubber, and a first pipe end closing member having a fluid inlet communicating into the pipe and fixed thereto so as to close one open end of the pipe. and a second pipe end closing member fixed thereto so as to close the other open end of the pipe, and the pipe has a second pipe end closing member fixed thereto so as to close the other open end of the pipe, and the pipe includes a second pipe end closing member for preventing the elastic wall from expanding in the radial direction. A telescopic cylinder characterized in that a coil spring is provided approximately concentrically with the axis of the pipe.

(2) The telescopic cylinder according to claim 1, wherein the coil spring is embedded in the elastic wall of the elastic pipe.

(3) The telescopic cylinder according to claim (1), wherein the coil spring is provided so as to surround an outer wall of an elastic pipe.

(4) A first sleeve is fixed to one of the end closing members so as to wrap around the elastic pipe and the coil spring, and a first sleeve is fixed to the other end closing member so as to wrap around the first sleeve. The telescopic cylinder according to claim 1, wherein the second sleeve is fixed so as to be slidable relative to the sleeve.
