自動車用ホイール
Document Type and Number:
Japanese Patent JP5452275
Kind Code:
B2
Abstract:
A front flange portion formed at an outer peripheral edge portion of a wheel disc includes an annular front peripheral portion provided on a design surface side and an annular back peripheral portion folded backward from the annular front peripheral portion to extend radially inwardly and in surface contact with a back surface of the annular front peripheral portion, and the annular front peripheral portion and the annular back peripheral portion are integrally inclined to the surface side. Therefore, the front flange portion can mitigate stress concentration on the front flange portion due to a load generated while the automobile is running. In addition, the front flange portion has, because of its shape, high durability against a radially inward load generated by a contact with a curbstone or the like.
