Claims

[Claims for Utility Model Registration] (1) A cylindrical elastic member 2 is disposed on the outside of a cylindrical hub 1 attached to a rotating shaft 12, and a cylindrical vibration ring 3 is provided on the outside of the elastic member 2. A plurality of elongated holes 4 facing in the circumferential direction are provided in the elastic member 2 at predetermined intervals in the circumferential direction, and each elongated hole 4
1. A dynamic damper characterized in that a stopper member 11 is provided which is in contact with the hub 1 in the radial direction and is fixed to the hub 1. (2) The stopper member 11 includes a stopper attachment fitting 5 that can be fixed to the hub 1, and a rod-shaped stopper 9 that is integrally attached to a portion of the stopper fitting 5 that corresponds to each elongated hole 4 of the rubber 2. The dynamic damper according to claim 1, wherein the dynamic damper is formed of. (3) The stopper member 11 is capable of coming into contact with the side surfaces of the hub 1 and the rubber 2, and has a stopper mounting bracket 5 that can be fitted onto the inner circumferential surface of the cylindrical hub 1.
and a rod-shaped stopper 9 having a threaded portion 8 into which a screw 10 passing through a hole 7 formed at a location corresponding to each elongated hole 4 of the rubber 2 of the stopper fitting 5 can be screwed. 3. The dynamic damper according to claim 2.
