To provide an intermediate bearing structure of a propeller shaft for improving assembling workability.SOLUTION: An intermediate structure 5 of a propeller shaft 1 comprises a bearing 8, an annular member 10a internally fit with the bearing 8, a bearing fixing member 9 in which a first end part in a rotation axial direction abuts on the bearing 8, and a shaft member 13 internally fit to the bearing 8. The bearing fixing member 9 comprises: a first cylinder part 9a; a second cylinder part 9b which is different from the first cylinder part 9a in an inside diameter, arranged while adjoining the first cylinder part 9a on the rotation axial direction, and has a curved face and a first plane part 9c at an internal peripheral face; and a circular plate part 9d arranged at a second end part of the bearing fixing member 9, being an end part of a side opposite to the first end part in the rotation axial direction, extending in a radial direction of the bearing 8, and having a tool engagement part 9e. The shaft member 13 comprises a second plane part 13d opposing the first plane part 9c, the first plane part 9c has a region in which a distance from a rotation axial core of the bearing 8 is shorter than a distance from a rotation axial core of the curved part, and the bearing 8 is gripped by the bearing fixing member 9 and the shaft member 13 in the rotation axial direction.SELECTED DRAWING: Figure 4

    【課題】組み付け作業性を向上させる推進軸の中間軸受構造を提供すること。【解決手段】軸受8と、軸受8を内嵌する円環部材10aと、回転軸方向の第1端部が軸受8に当接している軸受固定部材9と、軸受8に内嵌される軸部材13と、を備え、軸受固定部材9は、第1円筒部9aと、第1円筒部9aと内径が異なるとともに、回転軸方向に第1円筒部9aと隣接して備えられ、内周面に曲面部及び第1平面部9cを備える第2円筒部9bと、軸受固定部材9の、第1端部とは回転軸方向における反対側の端部である第2端部に備えられ、軸受8の半径方向に延在するとともに工具係合部9eを有する円板部9dと、を備え、軸部材13は、第1平面部9cと対向する第2平面部13dを備え、第1平面部9cは、軸受8の回転軸芯との距離が、曲面部と回転軸芯との距離よりも近い部位を有し、軸受固定部材9及び軸部材13により、回転軸方向で軸受8を挟持する推進軸1の中間軸受構造5。【選択図】図4
