PROBLEM TO BE SOLVED: To provide a joint device capable of attaining smooth rotation transmission even in a state where axial deviation between a driving shaft and a driven shaft occurs.SOLUTION: A driving side rotor 30 has a rotation transmission part 35 projecting to the side of a driven side rotor 40 in an axial direction, and the driven side rotor 40 has a rotation reception part 42 projecting to the side of the driving side rotor 30 in the axial direction. On the outer peripheral surface of a buffer member 50, provided are a first engagement recess part 51 where the rotation transmission part 35 can be engaged in a rotational direction, and a second engagement recess part 52 where the rotation reception part 42 can be engaged in the rotational direction. Then, an outer diameter D4 of the bottom surface of the second engagement recess part 52 is set smaller than an inner diameter D3 of the rotation reception part 42. |
