PROBLEM TO BE SOLVED: To provide a propeller shaft structure in which improvement in degree-of-freedom of design of a sealing device can be achieved while simplification of a construction can be achieved and improvement in a sealing performance against a center bearing can be achieved.SOLUTION: A sealing device includes a tube-shaped boot which surrounds the gap between the outside joint member of a constant-velocity universal joint and a center bearing and is capable of bending and moving telescopically. Regarding the boot, one end part is fitted to the outside joint member side of the constant-velocity universal joint through a bearing structure part, and the other end part is fitted to an annular support member side through the center bearing. The boot is restricted not to rotate in combination with rotation of a propeller shaft.SELECTED DRAWING: Figure 1

    【課題】構成の簡略化を図ることができ、かつ、センタベアリングに対するシール性の向上を図ることができるとともに、密封装置の設計の自由度の向上を図ることが可能なプロペラシャフト支持構造を提供する。【解決手段】密封装置は、等速自在継手の外側継手部材とセンタベアリングとの間の隙間を包囲する屈曲及び伸縮が可能な筒形状のブーツを有する。ブーツは、一端部が軸受構造部を介して等速自在継手の外側継手部材側に装着されるとともに、他端部が前記センタベアリングを介して環状支持部材側に装着される。ブーツは、プロペラシャフトの回転に伴った回転が規制される。【選択図】図1
