Claims

[Scope of Claim for Utility Model Registration] (1) A vibration isolator for supporting a vibrating body on a floor, which comprises: a lower metal fitting having a truncated cone shape and having a flange portion fixed to the floor surface on the outer periphery; having a frustoconical inner surface corresponding to the truncated conical outer surface of the metal fitting, and arranged above the lower metal fitting at a constant interval;
It consists of an upper metal fitting to which the vibrating body is fixed to the outer surface of the horizontal top part, and an integral horizontal part and a conical part that fill the space between the lower metal fitting and the upper metal fitting, the lower surface of which is the lower metal fitting,
A vibration isolator comprising a rubber body whose upper surface is vulcanized and bonded to the upper metal fittings, and which has a through hole in the center of the horizontal portion. (2) Claim 1 wherein the upper metal fitting and the lower metal fitting are made of spheroidal graphite cast iron, and the rubber body is made of natural rubber.
Anti-vibration device.
