    摘要： A power transmission shaft which can be evaluated on torsional fatigue strength based on a management indicator different from compressive residual stress in an outer surface. In a power transmission shaft having outer circumferential serrations 1a, 1b, torsional fatigue strength is evaluated by using compressive residual stress at a depth of 30 μm (and 50 μm) from an outer surface of a rising portion of each concave of the outer circumferential serrations 1a, 1b as a management indicator. A high torsional fatigue strength can be secured by having a compressive residual stress of 1150 MPa or more at a depth of 30 μm (and 50 μm) from the outer surface.

    摘要： A drive shaft is configured from a shaft body, a shaft portion provided with extensions and boot mounting parts coaxially and integrally formed on ends thereof, and constant velocity joints attached to ends of the extensions via interior members. The outer diameter of intermediate portions of the extensions is smaller than that of the ends and the boot mounting parts. Formed on the opening-sides of the inner surfaces of the exterior members of the constant velocity joints are flanks that face outward and leave a slight clearance with the intermediate portions. Edges forming the boot mounting part sides of the intermediate portions are set to positions corresponding to outer edges of the flanks, and tapered portions connect the edges and the boot mounting parts.

    摘要： A metal part in which a base material of silicon-aluminum alloy having 1 to 25% by mass of silicon as an anode is immersed in an electrolyte together with a cathode, and at least a portion of a surface of the base material is anodized and coated with an anodic oxide film. A current density provided to both the anode and the cathode is increased from an initial current density of 0 A/dm2 at a rate between 0.15 and 0.35 A/dm2 per minute, wherein once the current density reaches a prescribed current density of between 0.8 A/dm2 and 1.2 A/dm2, the current density provided to the anode and the cathode is maintained at the prescribed current density.
