自動車用ホイール
Document Type and Number:
Japanese Patent JP5374353
Kind Code:
B2
Abstract:
An inner peripheral end portion of an annular back peripheral portion forming a front flange portion, an opening end portion of a front bead seat portion and a back surface portion of a wheel disc are joined to each other by a first welded portion and a second welded portion. Accordingly, it is possible to prevent the front flange portion from being repeatedly elastically deformed by loads generated while the automobile is running. In addition, it is possible to mitigate a stress concentration generated on the front flange portion and the first welded portion and the second welded portion. Thus, an automobile wheel can exhibit high durability.
