PURPOSE:To suppress generation of cracks in a radial reinforced layer at a jointed portion of a power transmitting shaft made of fiber reinforced resin which is to be connected to a coupling element, and to cover up the cracks for preventing infiltration of water and oil even if cracks are generated. CONSTITUTION:In a jointed portion of a power transmitting shaft made of fiber reinforced resin which is to be connected to a coupling element, a torque transmitting layer 5, a radial reinforced layer 6 and a skin layer 7 are provided on the shaft (1) from the inside toward the outside. This torque transmitting layer 5 is a fiber reinforced resin layer having an orientation angle of fibers of 0-+ or -60 deg., and the radial reinforced layer 6 is a fiber reinforced resin layer in which fibers are wound with a helical angle of + or -75-+ or -90 deg.C, and the skin layer 7 is a fiber reinforced resin layer which has an orientation angle of fibers smaller at least by 20 deg. in absolute value than the helical angle of the fiber in the radial reinforced layer. |
