PROBLEM TO BE SOLVED: To provide a high-capacity flexible shaft coupling whose allowable transmission torque is increased without upsizing. SOLUTION: The flexible shaft coupling comprises input members 11, 13 and 15 input with force in a direction of rotation; output members 12, 14 and 16 outputting force in a direction of rotation; an elastic body 18 having an annular part 18b rotated in the circumferential direction, and having the input members 11, 13 and 15 and the output members 12, 14 and 16 embedded therein alternately so as to be apart in the circumferential direction; and a tensile strength member 21 or 26 provided in the elastic body 18 so as to transmit force in the rotation direction between the input members 11, 13 and 15 and the output members 12, 14 and 16 adjacent in the circumferential direction, wherein the tensile strength member 21 or 26 includes both end parts 21e, 21f, etc. engaging to each of the input members 11, 13 and 15 and the output members 12, 14 and 16 adjacent in the circumferential direction, and middle parts 21g, 21j, etc. positioned on the radial outer side of the elastic body 18 more than that.
