Abstract
In our laboratory, problem based learning type studies have been carried out as graduation research programs for several years. They are developments of equipments for environment and welfare. This report is concerned with the practical activities about manufacturing bear bells as one of these problem based learning programs. This program was carried out by the advanced engineering course students in the advance exercise for design fundamentals. Through manufacturing bear bells, our students understood that manufacturing design, considering of working process, and use of effective working jigs took very important role in manufacturing. In engineering (manufacturing) education at colleges, necessity of some practical design exercise related to manufacturing design and designing working jigs etc. are emphasized here.
