PURPOSE:To provide a light rigid cam shaft by a method wherein at least a shaft part of the cam shaft integrally provided with the shaft part, cam part and journal part is formed to a cylinder of fiber reinforced resin. CONSTITUTION:This cam shaft is composed of a shaft part 1, two cam parts 2 and two journal parts 3 arranged near both ends of the shaft part 1. The cam part 2 and the journal part 3 are integrally connected by an adhesive agent to the shaft part 1. Said shaft part 1 is formed of a tubular shape by a filament winding process or winding of preparegged tape immersed with thermosetting resin. The fiber is arranged to direct in an axial direction and a circumferential direction of the shaft part 1 and at the same time to form a multi-layered structure helically wound in a direction inclined at a specified angle. The cam part 2 is of a carbon fiber reinforced resin and formed to have an anti-friction covering layer such as metal vopour coating etc., on the surface of cam. |
