The impulsive riveting method can join the sheets without drilling as well as disjoin easily the jointed sheets. The joints made by the method have high joint strength and the deformation of the joints is also small. However, the equipment for the impulsive riveting is large in order to utilize the impulsive energy and the control of the impulsive energy is very difficult. Therefore, miniaturization and simplification of the equipment are necessary for the practical application. In this study, the punching rivet method that the sheets were joined by pressing the rivet without drilling was proposed and applied to the joining of cold-reduced carbon steel sheets. The deformation and the strength of the joints made by the method were examined in comparison with those of the joints made by caulking and the impulsive riveting method. The effectiveness of the proposed method was clarified from the experimental results..
