<p><P>PROBLEM TO BE SOLVED: To provide a golf club set for which a golf ball catching degree and the good quality of the return of a face surface are matched. <P>SOLUTION: In the golf club set having a plurality of golf clubs for which the loft angles of golf club heads are different from each other, when a value obtained by multiplying the acceleration component of the golf club head in a direction orthogonal to a hitting direction on a surface in parallel with the ground surface immediately before a golfer hits a golf ball, the retreat amount of a centroid position which is a distance along the hitting direction from the center axis of the golf club shaft of the golf club or the extension of the center axis to the centroid position of the golf club head and the mass of the golf club head of the golf club is defined as the first index of the golf club, with the first index of the golf club whose loft angle is the maximum among the plurality of golf clubs as a reference, the first indexes of any golf clubs are in the range of 75% to 100%. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
