<p>PURPOSE: To make it possible to accurately measure a golf club by a reference frame by rotatably providing a rotary plate at a base having a flat vertex, and holding a shaft to pass a rotary shaft perpendicularly to the shaft. CONSTITUTION: A base plate 41 is fixed so that a flat top surface 47 becomes horizontal, and a mounting plate 48 is fixed perpendicularly to it. A rotary plate 57 is rotatably supported by a shaft pin 53 as a rotary shaft X provided on the surface 47 of the plate 48. A club holding assembly is mounted at the plate 57 to maintain the shaft of the club at the reference position so that the shaft is passed at the centerline through the shaft X via a grooved roller 72. A ruler 80 is fixed to the plate 57, a measuring unit is provided, the distance from the shaft X is measured, and the length of the shaft is obtained by the scale at the end of the shaft. Thus, when the shaft is mounted on the assembly, the centerline is introduced to the shaft X of the reference point at the perpendicular plane, and they can be measured.</p> |
