PURPOSE:To enable a filament winding process to be applied to make a molding and improve a twisting strength at the junctions by a method wherein a shaft, conical surface parts with their diameters being increased toward outer ends of the shaft and outer circumferential surfaces of metallic coupling members to be fitted to the reduced diameter parts extended from the outer end surfaces of the conical surfaces are covered by a fiber reinforced synthetic resin layer. CONSTITUTION:A continuous fiber coated with resin is wound around a mandrel 31 while it is rotated to make an inner shaft 2. After the mandrel 31 is pulled out and an adhesive agent is coated to an outer end surface 13 of a conical surface part 12 and an outer circumferential surface of a reduced diameter shaft part 14, an inner circumferential surface of a cylinder part 21 is fitted to the outer circumferential surface of the reduced diameter part 14 of the shaft and then metallic coupling members 3, 3 are fixed to them. After the adhesive agent is coated on the outer circumferential surface of the cylinder 21, the continuous fiber body coated with resin is wound around the shaft 11 of the inner shaft member 2, conical surface part 12 and the outer circumferential surface of the cylinder 21 of the metallic coupling members 3 to form a fiber reinforced synthetic resin layer 4. Thereafter, they are heated together in a heating furnace to get a resin driving shaft 1. |
