Abstract
Excellent durability can be achieved by reducing thermal influences of the excessive load from the engine side for a clutch roller () in a unidirectional rotation clutch system that is helical-splined to a drive shaft that rotates in response to a driving force of a motor and structured such that the motor driving force can be transmitted while an engine driving force cannot be transmitted when an engine stars, wherein a compound film composed of an external mixed phase and an internal diffused phase is formed on the clutch roller () subjected to nitriding by tufftriding with nitrogen being penetrating and diffusing.
