Abstract
Herein disclosed is an elastic coupling using rubber or an elastomer as an elastic element. The elastic coupling includes an inner metal ring having its radially outer surface radially curvilinearly convexed, an outer metal ring having its radially inner surface radially curvilinearly convexed, and an elastomer ring interposed between the inner and outer metal rings and having its radially inner and outer surfaces correspoindingly radially cirvilinearly concaved as to be fitably secured, respectively, to the outer surface of the inner metal ring and to the inner surface of the outer metal ring. Thus, the modulus of shearing strain of the surface portions of the elastomer ring at the side is smaller than that of an inside portion of the same so as to eliminate any pretension of the surfaces of the elastomer ring.
