Parking gear is essential parts of automotive to park on flat or slope ground. Parking of, especially, big-sized vehicle such as bus and truck is very important problem related to safety. Stability of parking gear may differ from contact location between parking gear and pawl. The purpose of this study is to investigate the influence of stability depending on contact location using numerical analysis. Furthermore the results obtained by numerical analysis were applied to real vehicles to evaluate established-product of parking gear. As the results, safety criterion of parking gear showed below 0.31ton and thus it was confirmed that parking gear of this study was suitable to small-sized vehicle.
