A flexible coupling, for transmitting a great amount of torque from a drive shaft to a driven shaft by directing tensile force to act on connecting members, includes a pair of hub members mounted respectively on the drive shaft and the driven shaft, each hub member having two flanges with a space therebetween in the axial direction of the hub member. Each flange has projections projecting in the radial direction of the flange, each projection peripherally adjoining void spaces. The hub members as a pair are so constructed as to enable the projections of the flanges of one hub member to fit into the void spaces of the flanges of the other hub member, leaving a clearance between any facing portions of the flanges of the facing hub members with no contact therebetween. Retaining members are provided, each such member extending parallel to the axis of the hub member and having both ends thereof supported by the projections of the two facing flanges of each of the facing hub members. A plurality of laminated connecting members consisting of a plurality of sheet-like connecting elements are provided. Each such member is inserted into a space between the flanges so as to have one end thereof retained by the retaining member supported by the flanges of one hub member and the other end thereof retained by the retaining member supported by the flanges of the other hub member. The connecting members connecting the hub members are thus themselves formed into a polygonal link.
