Abstract
In an elastic coupling including first fixtures, second fixtures, a reinforcing member in a loop-like shape and an elastic covering member, the reinforcing member is made by connecting one longitudinal end and the other longitudinal end of a stranded wire. The stranded wire is formed by twisting the appropriate number of metallic wires. Since the metallic wires do not shrink by heat, the metallic wires do not shrink during the vulcanization. Thus, the variety of the spring constant of the elastic coupling can be reduced. Also, since the metallic wires are very strong, the number of winding the stranded wire around the first fixtures and the second fixtures can be reduced and therefore the size of the elastic coupling can be prevented from increasing.
