Claims

[Claims for Utility Model Registration] (1) A vibration ring 5 is attached to the outer periphery of a cylindrical hub 1, 21 that is connected to a rotating shaft and rotates together with the rotating shaft, via an annular rubber elastic member 3, 23. , 25, one end of the hub 1, 21 extends radially outward to form an edge 8, 28 facing one side of the vibration ring 5, 25,
, 21, the vibration rings 5, 2 are arranged in a disc shape.
5, and on the outer periphery,
Plates 6, 26 having locking portions 11, 31 facing the outer peripheral surfaces of the vibration rings 5, 25 are provided,
A sliding member 12, 32 attached to the plate 6, 26 is provided between the inside of the locking portion 11, 31 of the plate 6, 26 and the outer peripheral surface of the vibration ring 5, 25.
A torsional damper characterized by being provided with. (2) The vibration ring 25 has at least two circumferential grooves 29 equally spaced on its outer circumferential surface, and the plate 26 has grooves 29 disposed on its outer circumferential surface at equal intervals.
A locking portion 31 is provided between the vibration ring 25 and the groove 29 and facing the bottom surface 35 of the groove 29, and the locking portion 31 is located between the inside of the locking portion 31 and the bottom surface 35 of the groove 29. A sliding member 32 is disposed inside the stopper 31 so that when the vibration ring 25 moves in the circumferential direction with respect to the hub 21, the stopper 31 comes into contact with the end surface 34 of the groove 29. 2. The torsional damper according to claim 1, wherein further fluctuation is prevented.
