To fix a rotary shaft to a rotary plate without using press-fitting.SOLUTION: A fixing structure between a rotary plate 20 and a rotary shaft 10 includes: a rotation stop plate 30 (a rotation restriction member) which is formed with a hole 31b, to which the rotary shaft 10 is fixed, and in which an outer peripheral edge 31a around an axis C of the rotary shaft 10 is formed in an irregular shape; a rotary plate 20 having a hole 21c of an inner peripheral edge which engages with the outer peripheral edge 31a of the rotation stop plate 30 and has an irregular shape; and two rotation plate pressing plates 41, 42 which sandwich the rotary plate 20 from both sides as seen in an axis C direction of the rotary shaft 10 and are fixed to the rotary shaft 10.SELECTED DRAWING: Figure 2 【課題】回転板に対して回転軸を圧入することなく固定する。【解決手段】回転板２０と回転軸１０との固定構造において、回転軸１０が固定される孔３１ｂが形成され、回転軸１０の軸心Ｃ回りの外周縁３１ａが異形に形成された回転止め板３０（回転規制部材）と、回転止め板３０の外周縁３１ａと係合した異形の内周縁の孔２１ｃを有する回転板２０と、回転板２０を回転軸１０の軸心Ｃ方向の両側から挟んだ、回転軸１０に固定された２つの回転板押さえ板４１，４２と、を備える。【選択図】図２
