Claims

[Claims for Utility Model Registration] (1) An annular vibration ring 7 is provided on the outside of the annular hub 1, and an elastic body 6 is positioned between the parts facing each other in the axial direction, so that the vibration between the annular hub 1 and the vibration ring 7 is provided. The hub 1 and the vibration ring 7 are integrated with each other.
A dynamic damper characterized in that a stopper member 10 is provided between the vibration ring 7 and the vibration ring 7 to limit displacement in the radial and axial directions. (2) An annular sleeve 4 having a flange 5 extending radially outward at one end is integrally provided on the outer circumferential surface of the annular hub 1, and is spaced a predetermined distance from the outer circumferential surface of the hub 1. furthermore, the vibration ring 7 and the flange portion 5 of the sleeve 4 are integrally connected via an elastic body 6, and the hub 1 and the vibration ring 7
A dynamic damper characterized in that a stopper member 10 is provided between the vibration ring 7 and the vibration ring 7 to limit displacement in the axial and radial directions. (3) The dynamic damper according to claims 1 and 2, wherein the elastic body 6 is provided in an annular shape. (4) The dynamic damper according to Claims 1 and 2, wherein the elastic bodies 6 are provided at predetermined intervals in the circumferential direction. (5) An annular step 9 is provided on the inner peripheral surface of the vibration ring 7, and a step 11 that engages with the step 9 of the vibration ring 7 is provided on the outer peripheral surface of the stopper member 10. 3. A dynamic damper according to claim 2, wherein said vibration ring is provided with a damper, thereby limiting displacement of said vibration ring in the radial and axial directions.
