Abstract
An elastic coupling, wherein drive side and driven side collars can be press fitted easily, securely and firmly to inner cylinder members with a sufficient interference and which can be used without a danger of axial deviation or disconnection and can be enhanced in durability and reliability. It comprises drive side collars and driven side collars arranged equidistantly on a concentric circle and alternately; belt-like fiber bundles wrapping around adjacent collars; and an elastic material embedding the collars and the belt-like bundles. Cylindrical parts of the collars are integrally formed, on outer peripheries thereof with plural flange parts for holding the belt-like bundles and fitted to inner cylinder members. A central area of each of the inner peripheries of cylindrical parts is formed as a radially expanded portion from the other portion.
