Abstract
Provided is a rigidity characteristics measuring device that measures the rigidity characteristics of a golf club head. A head fixing jig holds the golf club head with a face surface facing upward. A linear bushing causes an impact rod to drop vertically toward the golf club head. The impact rod is equipped with an acceleration sensor. A computer calculates the rigidity characteristics, e.g., a CT value, of the golf club head, based on a detected value of the acceleration sensor.
