PURPOSE:To promptly restrain vibration of a shaft and to prevent the shaft from slipping off in the axial direction by interposing a gel substance in a circumferential gap between a shaft mounting body and an inertia body and in a sideway gap between the shaft mounting body and a resisting wall portion. CONSTITUTION:The outer peripheral surface of a damper portion 12 of a shaft mounting body 1 and a trough portion 13 and a crest portion 23 of the inner peripheral surface of an inertia body 2 confront to each other with an inclination and have such a dimensional relationship as to overlap one another. When external force is applied either to the shaft mounting body 1 or to the inertia body 2, or both of them, the gel substance 3 is forced to generate compressive force by the trough portion 13 and crest portion 23. Thus, vibration of a shaft can be promptly restrained so as to prevent the shaft from slipping off in the axial direction. |
