In this paper, we relate the golfer's cock and roll motions in the golf driver swing and eight club head and/or ball motions (head velocity, ball velocity, upper angle, side angle, back spin, side spin, carry and traverse) by experiment and statistical method. First, to be measured cock and roll motion variables, we used the three dimensional gyro sensor that we developed. Second, by using measured cock and roll motion variables, we classfied with three groups by cluster analysis. By the multiple regression analysis method, the relation between selected 3 variables and eight club head and/or ball motions was estimated. As result of giving official approval accuracy of estimated regression equation with Adjusted R-square and analysis of variance, the equation of head velocity, ball velocity and carry had the significance. Finally, we extracted the cock and roll motions that affected head velocity, ball velocity and carry. From the sensitivity analysis, we found that the most important factors in improving the three motions are (1) angular velocity of roll is slower, (2) angle of cock is smaller, (3) when cock angle arised in driver swing, angular velocity of cock is faster.
