AUTOMOTIVE WHEEL
摘要:
The present invention proposes an automotive wheel that can exhibit high strength and high durability. The automotive wheel includes a wheel disc in which a hat section is provided outside a hub mounting section, and a hat inner inclined surrounding section of the hat section includes an inner convex surrounding section protruding to a surface side in a curved shape, and an inner lower concave surrounding section continuously formed with an inner peripheral edge of the inner convex surrounding section, continuously formed with an outer peripheral edge of a hub surface rounded section, and protruding to the back side in the curved shape. The automotive wheel according to the present invention can reduce the stress concentration on the hub surface rounded section which is produced by the lateral force applied during the traveling of the automobile, and therefore high strength and high durability can be provided.
