摘要:
A golf ball with three dimples (14) having the same shape and an equal diameter and an equal depth are distributed about the center of each spherical regular triangle (13) such that three line segments connecting the centers of the three dimples (14) define a regular triangle (15). The length of each line segment, that is, length (D.sub.D1) of one side of the regular triangle (15) does not exceed twice the diameter (D.sub.m) of the dimples (14). No other dimples are located within the regular triangle (15) associated with the three dimples (14). Two dimples (16) having the same diameter as the three dimples (14) are distributed on each side of the spherical regular triangle (13) in symmetry with respect to its middle point such that the distance (D.sub.D2) between the centers of the two dimples (16) does not exceed twice the diameter (D.sub.m) of the dimples (16).
