<p><P>PROBLEM TO BE SOLVED: To accurately measure the natural vibration frequency of a golf club by a simple structure and to measure the weight, swing weight and natural vibration frequency of the golf club with a single instrument. <P>SOLUTION: One end side of an action plate 2 where a clamper 3 is arranged is supported by a supporting member 7, the other end side is supported by a measuring base 4 provided with a load cell, the action plate is vibrated by giving vibrations to the shaft of the clamped golf club, and the natural vibration frequency of the golf club is measured by the output signal of the load cell by the vibrations. Also, the action plate is supported by a first supporting member 5 and a second supporting member 6 capable of canceling support and the measuring base provided with the load cell, the swing weight is measured by canceling the support of the first supporting member, the weight is measured by canceling the support of the first supporting member and the second supporting member, and the natural vibration frequency is measured by canceling the support by the second supporting member. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
