PROBLEM TO BE SOLVED: To provide a fastening structure which can suppress an inclination of a first member to a second member at the pressure-insertion of an axial side spline and a hole side spline.SOLUTION: A fastening structure 10 fastens a first member 1 and a second member 2 by using a screw member 3. The first member 1 comprises a fastening part 1b. An axial side spline 1f is formed at an external periphery of the fastening part 1b, and an introduction internal peripheral face 1i extending along an axial line direction is formed at a tip of a screw thread 1h of a screw hole 1c. In the second member 2, a hole side spline 2d which is pressure-inserted into and engaged with the axial side spline 1f is formed, and an abutted face 2f orthogonal to the axial line direction is formed. In the screw member 3, a head part 3h and a shaft part 3c are formed. In the head part 3h, an abutment face 3d abutting on the abutted face 2f is formed while extending to a direction intersecting with the axial line direction, and a guide fitting part 3f which is fit to the introduction internal peripheral face 1i is formed at a tip of the shaft part 3c.SELECTED DRAWING: Figure 1

    【課題】軸側スプラインと穴側スプラインとの圧入時に、第一部材が第二部材に対して傾くことを抑制することができる締結構造を提供する。【解決手段】 締結構造10は、第一部材1と第二部材2とをネジ部材3によって締結する構造であって、第一部材1は、締結部1bを備え、締結部1bの外周面に軸側スプライン1fが形成され、ネジ穴1cのネジ山1hの先端には軸線方向に沿って延在する導入内周面1iが形成され、第二部材2は、軸側スプライン1fに圧入して係合される穴側スプライン2dが形成されるとともに、軸線方向と直交する被当接面2fが形成され、ネジ部材3は、頭部3hと軸部3cが形成され、頭部3hに被当接面2fと当接する当接面3dが軸線方向と直交する方向に延在して形成され、軸部3cの先端部に導入内周面1iと嵌合する案内嵌合部3fが形成されている。【選択図】 図1
