PROBLEM TO BE SOLVED: To disclose a joint which can absorb "the displacement of an axial center between an input shaft and an output shaft" and "displacement in an axial line direction" while transmitting a rotation force, and is reducible in a dimension in the axial line direction.SOLUTION: A first engagement face 26B which is substantially parallel with a first direction L1 orthogonal to an axial line direction of an output shaft 23G being the first engagement face 26B which slidably pressure-contacts with the output shaft 23G, and is engaged therewith are formed at an inner wall face of a first engagement hole 26A. A second engagement face 25B which is substantially parallel with a second direction L2 orthogonal to the first direction L1 being the second engagement face 25B which slidably pressure-contacts with a second coupling member 26, and is engaged therewith are formed at an inner wall face of the second engagement hole 25A. By this constitution, an Oldham joint is constituted. "The displacement of an axial center between an input shaft and the output shaft 23G" can be thereby absorbed. "Displacement in the axial line direction" can be absorbed by adjusting a fit-in dimension in the axial direction.SELECTED DRAWING: Figure 5

    【課題】 回転力を伝達しながら「入力軸と出力軸との軸中心のずれ」及び「軸線方向のずれ」を吸収可能な継ぎ手であって、軸線方向寸法の小型化が可能な継ぎ手を開示する。【解決手段】 第1係合穴26Aの内壁面には、出力軸23Gの軸線方向と直交する第1方向L1と略平行な第1係合面26Bであって、出力軸23Gと滑り可能に圧接して係合する第1係合面26Bが設けられている。第2係合穴25Aの内壁面には、第1方向L1と直交する第2方向L2と略平行な第2係合面25Bであって、第2カップリング部材26と滑り可能に圧接して係合する第2係合面25Bが設けられている。これにより、オルダム継ぎ手が構成される。したがって、「入力軸と出力軸23Gとの軸中心のずれ」を吸収でき得る。軸方向の嵌り込み寸法を調節することにより「軸線方向のずれ」を吸収でき得る。【選択図】 図5
