In golf, the direction of the hit ball just after impact is influenced by various motions. These are body rotational and tranlational motion, ball side spin, incidence angle of club head and so on. Especially, body motion influences the direction of the hit ball greatly. In this paper, we related the golfer's rotational and tranlational motion, in the golf swing to the direction of the hit ball just after impact by experiments and examined the relationship by non-linear distinction analysis. As results, we clarified the body motions that affected the direction of the hit ball. The results are as follows.(1) The direction of the hit ball toward the right is proportional to the angle around the x-axis and inversely proportional to the angle around the y-axis of the left fore arm at the impact point.(2) The direction of the hit ball toward the right is proportional the angle around the y-axis of shoulder at the impact point.(3) The direction of the hit ball toward the right is proportional to the angle to the front displacement of the shoulder.
