    Main purpose of this study was to clarify the coaching nodes which were defined as the invariant coaching points in pitching mechanics among the experienced coaches. We also investigated the differences of opinion to the coaching points between the experienced coaches and the novices or non-experienced coaches, and among the experienced junior high school coaches, the experienced high school coaches, and the experienced ex-professional pitchers. We got 1,833 replies of questionnaires consisting of 30 items, from the ex-professional baseball players, high school baseball coaches, and junior high school baseball coaches. Several items were regarded as the coaching nodes or semi-coaching-node for all levels in this study, and another item was regarded as the coaching node for only the junior high school players.
