<p><P>PROBLEM TO BE SOLVED: To provide a shaft behavior measuring instrument capable of correctly and simply evaluating the degree of "front bending angle", "toe-down amount", or "flex speed" in swinging of each golfer. <P>SOLUTION: The shaft behavior measuring instrument comprises: a strain measurement unit 100 for measuring the strain of a prescribed position in a shaft when the golfer swings; a storage part 300 for storing a table 200 indicating relation between a strain amount around an impact in the swing of the golfer and the largeness (higher or lower) of different parameters concerning the shaft behavior; an evaluation unit 400 for evaluating the largeness (higher or lower) of the parameters step by step, based on the measurement result by the strain measurement unit 100; and a display device 500 for displaying the evaluation result by the evaluation unit 400. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
