PROBLEM TO BE SOLVED: To provide a shaft connecting structure which is excellent in durability.SOLUTION: A shaft connecting structure 40 includes a first member 50 into which a first shaft 14a is fit and inserted, a second member 60 into which a second shaft 18 is fit and inserted and an intermediate member 70. The intermediate member 70 includes a third main body part 71, a third connecting protrusion 72, a preload part 73 and a connecting part 80. The third connecting protrusion 72 is gripped between a first connecting protrusion of the first member 50 and a second connecting protrusion 62 of the second member 60 in a peripheral direction Z. The preload part 73 is arranged inside a radial direction of the third main body part 71, and gripped between an end face 14c of the first shaft 14a and an end face 18d of the second shaft. The connecting part 80 includes an external peripheral part 81 (outer end part) connected to the third main body part 71, an internal peripheral part 82 (inner end part) connected to the preload part 73 and an undulation part 83 undulating between the external peripheral part 81 and the internal peripheral part 82 in an axial direction X.SELECTED DRAWING: Figure 4
【課題】耐久性に優れた軸連結構造を提供する。【解決手段】軸連結構造40が、第1シャフト14aが嵌入された第1部材50と、第2シャフト18が嵌入された第2部材60と、中間部材70とを含む。中間部材70は、第3本体部71と、第3連結突起72と、予圧部73と、連結部80とを含む。第3連結突起72は、第1部材50の第1連結突起と第2部材60の第2連結突起62との間で周方向Zに挟持される。予圧部73は、第3本体部71の径方向内方に配置され、第1シャフト14aの端面14cと第2シャフトの端面18dとの間に挟持される。連結部80は、第3本体部71に接続された外周部81(外端部)と、予圧部73に接続された内周部82(内端部)と、外周部81と内周部82との間で軸方向Xに起伏する起伏部83とを含む。【選択図】図4
