摘要：A method for measuring figure of deflection of a golf club shaft, including thesteps of horizontally orienting the golf club shaft along an x-axis and fixing a grip end ofthe 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 nearthe free end thereof to form a deflection curve of the golf club shaft, and obtaining thelocation of an intersection point of a tangent of the deflection curve and the x axis. Thetangent is obtained at the load applying point or in the vicinity of the load applying pointon the free end side of the golf club shaft. The method further includes the step ofdetermining a distance between the intersection point and a specific point on the golfclub shaft to obtain a parameter which represents the figure of deflection of the golfclub shaft.
