AUTOMOBILE UNDERCARRIAGE COMPONENT

摘要

The present invention addresses the problem of providing an automobile undercarriage component (10) that achieves a reduction in weight while minimizing losses in strength and rigidity. This automobile undercarriage component (10) is provided with a web and a rib and is characterized by: the rib being configured so as to comprise a first section that is a section having the widest width and a second section that has a narrower width than the first section; and the second section having a narrower rib width than the first section as a result of an inner wall surface of the second section that is continuously formed from the web being provided so as to be adjacent to a facing outer surface wall.
