PROBLEM TO BE SOLVED: To enable an oscillation-proof device to be manufactured in a simple structure, at a low cost and with a light weight by vulcanizing and sticking an elastic member between a sleeve shaft and a stabyoke, rotation directional and axial vibrations are restricted by means of an elastic member at the time of a low load and rotation direction load is received at the time of a high load. SOLUTION: In a space part between the shaft part 1a of a stabyoke 1 and the internal peripheral part of a sleeve shaft 3, an elastic member 2 vulcanized and stuck to the shaft part 1a of the stabyoke 1 and a sleeve shaft 3 is provided. During a low load time, torque is received by the elastic member 2 while coming in a floating state in axial direction so that any axial vibration inputted in a propulsion shaft can be absorbed by the elastic member 2. During a high load time, by providing such a structure as receiving torque as a stopper in the twisting direction by means of serration 4 formed by meshing and engaging with the shaft part 1a of the stabyoke 1 and the sleeve shaft 3, manufacture can be carried out at a low cost so as to be able to constituted a joint provided with vibration shielding characteristic in the axial direction. |
