Claims

[Scope of utility model registration request]

A vibration isolation support mechanism in which an elastic body is interposed between a vibration source and a base member, and a shaft member coupled to either one of the vibration source and the base member is inserted inside the elastic body, The shape of either the inner surface of the inside of the elastic body or the outer surface of the shaft member is adjusted so that the inside of the elastic body and the shaft member contact each other only at the intermediate portion in the axial direction. . A contact portion reduction type vibration-proof support mechanism, characterized in that it is formed in a tapered shape so as to be separated from the other surface as it goes outward from the intermediate portion in the axial direction.
