Abstract

PURPOSE:To always provide a constant slow reset time by making the frictional resistance between a sleeve slidably armored on the piston rod peripheral surface and a suspended cylindrical portion integrated with a cylinder, large than that between the sleeve and the piston rod. CONSTITUTION:A sleeve 29 is provided between the inner periphery 28' of a suspended cylindrical portion 28 of a cylinder cover 7' and the outer periphery 14' of a piston rod 14. The inner periphery 29' of the sleeve 29 is airtightly fitted in the outer periphery 14' of the piston rod 14, and the outer periphery 29'' of the sleeve 29 is lightly fitted in the inner periphery 28' of the suspended cylindrical portion 28 of the cylinder cover 7'. Furthermore, a ring groove 30 is provided on the outer periphery 29'' of the sleeve 29, and a ring 31 that has been energized so as to expand the inner periphery 28' of the suspended cylindrical portion 28 is fitted in the groove 30, and the frictional resistance between the suspended cylindrical portion 28 and the sleeve outer periphery 29'' with the ring 31 is made larger than that between the outer periphery 14' of the piston rod 14 and the inner periphery 29' of the sleeve 29.
