Abstract

PURPOSE:To make it possible to obtain a high and stable resistance by interposing such means between a drive shaft and a piston as is operative to convert the rotational motions of the drive shaft into the linear movements of the piston. CONSTITUTION:When a shaft 10 turned, its cam groove 10C is also turned together so that a pin 4 engaging with the cam groove 10C is moved rightward while rotating along the cam groove 10C. As a result, a piston 2 moves rightward within a pressure chamber 1a so that the working oil in a chamber B flows into a chamber A through an orifice 2a. At this time, the moving velocity of the piston 2 is reduced by the flow resistance in the orifice 2a so that the rotational motions of the shaft 10 are subjected to shock absorption.
