Abstract

In this paper, I focus on the rule of core supplier at the time of next generation vehicle development in the Japanese automobile industry. Special tooling die makers mass produce the main component motor core for automobile companies in Japan. Why they become the main component supplier? What type of close relationships exist between each die maker and the automobile company? The die maker receives the development information about the next generation vehicle from each automobile company. I analyzed a rule of core supplier that mass produced the main component motor core.
