Abstract
In this study, the analysis of stress distribution generated to die automobile hub by the cornering force caused when turning had done for discuss optimum structure. The experiment used the model of automobile hub made with epoxy resin, the assumption parts of the bearing and brake plate and increased load to die automobile hub by using the assumption parts of die bearing. The analysis method was die photoelasticity. It was became clear by die analysis that die stress concentration by die cornering force became remarkable at the fillet R neighborhood in die boss root, die bolt hole, and die contact department with die brake plate. It is thought that optimum automobile hub can be made by discussing structure of die three points when designing.
