PROBLEM TO BE SOLVED: To provide a transmission device that can reliably perform the stop of turning and the stop of pulling out when a polygonal shaft is fixed to a rotating member, and also can eliminate backlash.SOLUTION: A transmission device 60 includes a rotating member 62 having a mounting hole 67 in a rotation center, and a polygonal shaft 61 press-fitted to the mounting hole 67 of the rotating member 62. On an inner circumferential face of the mounting hole 67 of the rotating member 62, a plurality of inward projections 71 are arranged along a circumferential direction. While the polygonal shaft 61 is fitted to the mounting hole 67 of the rotating member 62, each of the inward projections 71 is abutted on an outer circumferential flat face 75 of the polygonal shaft 61. |
