PROBLEM TO BE SOLVED: To provide an elastic coupling of good prductivity without dispersing a torsional spring characteristic and without disordering ring shape of a reinforcing material. SOLUTION: This coupling comprises a flat plate-shaped elastic unit 1 concentrically drilled with a plurality of circular through holes 1a, plurality of collars 2a to 2d secured to the circular through hole 1a and a ring-shaped reinforcing material 3 linked in surpliced shape in the adjacent two collars 2a to 2d to be buried in the elastic unit 1. The reinforcing material 3 is a laminate of a plurality of tapes 6 integrally formed in a condition arranging a plurality of reinforcing threads 4 coated with a thermoplastic elastomer 5 in a parallel state. |
