<p>PROBLEM TO BE SOLVED: To stabilize the rigidity balance and the strength balance of a shaft by a method wherein for at least one sheet of main body prepregs, the winding amount is made less at a specified location in the axial direction, and an auxiliary prepreg is provided within the reduced winding amount at the location where the winding amount has been reduced. SOLUTION: The winding amounts of main body prepregs 8a, 8b, 10, 13 are reduced at specified locations, and at the same time, auxiliary prepregs 6, 7, 9, 11, 14, e.g. the auxiliary prepregs 6, 7, 9, 14 having characteristics being different from the characteristics of the main body prepregs are arranged at the locations where the winding amounts have been reduced, and thus, the characteristics of the main body prepregs 8a, 8b, 10, 13 are suppressed so as to be less, and characteristics being different from them are increased. In this case, the winding amounts (the winding number of times and the thicknesses when being wound or the like) of the auxiliary prepregs 6, 7, 9, 14 are kept within ranges by which the winding amounts of the main body prepregs are reduced, and thus, the characteristics which are different from the characteristics of the main body prepregs can be effectively displayed.</p> |
