ABSTRACT:
A rotary member such as a member of a bearing, a rotating member of a transmission or a gear for a motor vehicle, includes a base region of a ferrous base material such as a steel. The rotary member is formed with a hydrogen blocking layer formed in a contact surface for contacting with a mating body in a relative motion. The hydrogen blocking layer includes a concentrated portion formed in the base region and made of a substance lower in hydrogen diffusion coefficient than the base material.
