An elastic coupling for connection between two shafts, driving and driven, to transmit power from one to the other shaft, comprising a disc having a central hole formed therein; a plurality of cylindrical members for connection to a driving shaft, disposed equidistantly from each other on a circle concentrical to the disc; and a plurality of other cylindrical members for connection to a driven shaft, disposed as regularly spaced on the circle on which the first cylindrical members are disposed, the first and second cylindrical members being laid alternately as regularly spaced from one another, the cylindrical members being surrounded at the circumference thereof each by an elastic member of rubber, adjacent ones of the elastic members being coupled to each other by means of the disc. Each of the elastic members is cut at the inner end portion thereof nearer to the center of the disc to avoid a full joining thereof to the disc, while it is exposed at the outer end portion thereof away from the disc center to also avoid a full joining thereof to the disc. Thus the elastic members are joined to the disc at the portions thereof other than their respective inner and outer portions.
