- the corresponding parts are denoted by the same reference numerals and the illustration is omitted.
- the end rigid members 43 and 44 are fitted and fitted inside the outer cylinder 40 at both shaft end portions of the outer cylinder 40, respectively.
- Wide concave grooves (circumferential grooves) 49 and 50 are formed in the outer peripheral portion where the end rigid members 43 and 44 are fitted to the inner peripheral surface of the outer cylinder 40.
- O-rings 51 and 52 made of rubber-like elastic material are fitted in the concave grooves 49 and 50, respectively.

It is configured as a wide O-ring groove whose width dimension is sufficiently wider than the wire diameter of O-rings 51 and 52 (about 2 to 2.5 times the wire diameter).
- the free dimension state means a state where the O-rings 51 and 52 are not elastically deformed.
- metal collar members 53, 5 adjacent to the O-rings 51, 52 in the width direction are provided. 4 is arranged.
- the collar members 53 and 54 are divided into at least two parts so as to be fitted into the concave grooves 49 and 50.
- the outer side of the end rigid members 43 and 44 from the O-rings 51 and 52 (right end rigid member) 44 is located adjacent to the right side of the O-ring 52 in the groove 50, and is movable in the axial direction (left-right direction) in the grooves 49, 50.
- the outer diameters of the collar members 53, 54 mounted in the concave grooves 49, 50 are set to be equal to or smaller than the outer diameters of the end rigid members 43, 44.
- the end rigid members 43, 44 are formed with threaded holes 55, 56 that open from the outer end surfaces of the end rigid members 43, 44 to the groove side walls of the concave grooves 49, 50.
- a plurality of screw holes 55 and 56 are provided around the circumference of the end rigid members 43 and 44, and screw members 57 and 58 are screw-engaged with each of the screw holes 55 and 56, respectively.

- the O-rings 51 and 52 are all housed in the concave grooves 49 and 50, and the O-rings 51 and 52 do not protrude beyond the outer peripheral surface of the end rigid members 43 and 44. Without being pressed against the inner peripheral surface of the cylinder 40, the end rigid members 43 and 44 can be smoothly and easily inserted into the thin outer cylinder 40 with low frictional resistance. This also prevents the O-rings 51 and 52 from being damaged during the insertion operation.
