PROBLEM TO BE SOLVED: To provide a propeller shaft whose durability can be improved, by regulating displacement in the radial direction of a shock absorbing part arranged in an intermediate part of an intermediate shaft and absorbing a shock in the axial direction. SOLUTION: This shock absorbing part 60 constitutes the intermediate shaft 11, and absorbs the shock by contracting in the axial direction when the shock in the axial direction is applied to the propeller shaft 1. This shock absorbing part 60 is inserted into a hollow regulating member 65 so that displacement in the axial direction can be performed in a shock. The shock absorbing part 60 is molded in a hollow bellows shape out of a steel raw material, and is formed as a structure of continuing a plurality of tip-pointed bending parts 60a. The regulating member 65 is molded by using C-FRP and STKM as a raw material. COPYRIGHT: (C)2009,JPO&INPIT
