PURPOSE:To improve rigidity and wear resistance of a spring while eliminating air flowing into a tail cylinder from a liner by mounting a separate spring also between the inside of the spring and the liner, in a supporting structure wherein the spring is mounted to an end part of the liner inserted to the tail cylinder. CONSTITUTION:A spring 3, formed by bending a thin plate into a circular arc shape, is mounted on an end peripheral surface of a liner 1 on the side of a tail cylinder 2. Many slits 4 are formed in an axial direction of the liner 1. Further, a rear end part 5 of the spring 3 is spot welded by a spot 6 to the liner 1. Also between the inside of the spring 3 and the liner 1, a similarly formed spring 3' is mounted. In a condition that the liner l is completely inserted into the tail cylinder 2, both the outside/inside springs 3, 3' are overlapped with each other, and also the respective slits 4, 4' are displaced from each other. In this way, rigidity and wear resistance of the spring 3 are improved while eliminating air flowing into the tail cylinder 2 from the liner 1.
