FLEXIBLE JOINT

PROBLEM TO BE SOLVED: To provide a flexible joint capable of increasing respons by increasing a torsion spring constant. SOLUTION: A transmission claw 21 of a second connection member 2 is inserted between both transmission claws 20 of a first connection member 1 adjacent to each other in the direction of rotation X, a transmission claw 20 of the first connection member 1 is inserted between both transmission claws 21 of the second connection member 2 adjacent to each other in the direction of rotation X, and an elastic body 3 is provided between both transmission claws 20 and 21 adjacent to each other in the direction of rotation X. Both reference lines L passing through an eccentric central line C at an eccentric position from rotation central lines 10a, 18a of a transmission shaft and extending onto an outer peripheral side on both sides in the direction of rotation X among the rotation central lines 10a, 18a of the transmission shaft and the transmission claws 20, 21 are assumed, the transmission claws 20, 21 have side faces 26 provided on both reference lines L, and the elastic body 3 has a part 3a provided between the side faces 26 of both transmission claws 20, 21 being adjacent to each other in the direction of rotation X.
