Abstract
A method for measuring figure of deflection of a golf club shaft, including the steps of horizontally orienting the golf club shaft along an x-axis and fixing a grip end of the golf club shaft to form a cantilever, deflecting the golf club by applying a predetermined load at points on the golf club shaft located on the side of the shaft near the free end thereof to form a deflection curve of the golf club shaft, and obtaining the location of an intersection point of a tangent of the deflection curve and the x axis. The tangent is obtained at the load applying point or in the vicinity of the load applying point on the free end side of the golf club shaft. The method further includes the step of determining a distance between the intersection point and a specific point on the golf club shaft to obtain a parameter which represents the figure of deflection of the golf club shaft.
