Patent ID: 8888603

Claim:
A swing analyzer capable of outputting information usable for analyzing a swing of a user swinging a golf club including a shaft extending in a longitudinal direction and a head portion provided at one end of said shaft, comprising: a toe down strain gauge provided on the shaft of said golf club and capable of measuring strain in toe down direction of said shaft; a built-in processing unit calculating an expected bending point value corresponding to a position of bending point of said shaft; and a built-in display unit capable of displaying an output value from said built-in processing unit; wherein said built-in processing unit calculates said expected bending point value based on a measured value of said toe down strain gauge at a first time point during a swing of the user and on a measured value of said toe down strain gauge at a second time point preceding said first time point; said built-in processing unit stores in advance conversion data for converting said expected bending point value to recommended kick point output value; said recommended kick point output value is an output value representing the expected bending point value of said shaft; said built-in processing unit outputs said recommended kick point output value corresponding to said calculated expected bending point value to said built-in display unit; and said toe down strain gauge is provided between a position of 304 mm and a position of 381 mm from said other end of said shaft.
