When a bar collides perpendicularly against center of a beam, intermittent type collision was occurs repeatedly until the half-cycle of the beam's deformation motion is accomplished. In this paper, the details of collision process and motion mechanism is shown precisely and the effect of principal key factor also be shown by analytical and experimental approach. The movement of a bar and a beam are shown analytically and the impact force pattern is shown experimentally. The results of experiment showed the tendency which agrees on two key factors of 1) mass ratio and 2) 1'st natural frequency ratio. If a value of each key factor was determined, collision pattern of intermittent also be settled, and these patterns appear as the phenomenon of similar figure along the time axis was clarified from this experiment.
