Abstract
Disclosed is a method of manufacturing a sliding cam assembly. In particular, a requirement for wear resistance of a hollow tubular portion in which sliding takes place can be satisfied due to a cam piece being fixed to the hollow tubular portion by diffusion bonding while the sliding cam assembly repeatedly slides along a shaft, and each component can be separately machined and combined, thus minimizing an amount which is wasted at the time of machining, reducing the machining time, and rendering a separate heat treatment of a cam piece unnecessary.
