The purpose of this research is to examine the technique to be able to transmit the skill to the nonskilled person from the feature of the swing of a skilled person. In this research, the upper limbs are imitated by the rigid link model, and the torque in each joint is calculated by using the Newton-Euler method. Next, the reproducibility of the swing and the motion of upper limbs when swinging are analyzed from coordinate data by using the singular value decomposition. The result shows the problem of the nonskilled person's swing is low reproducibility and the occurrence of needless torque. Then, the follows were found that the gap of the swing can be improved by obtaining a singular value axially each. A needless torque is suppressed by greatly moving the left arm. It was confirmed that the skill can be transmitted from the two techniques.
