Abstract
In a golf ball having a parting line formed at the junction between a pair of mold sections and a plurality of dimples some of which lie across the parting line, the average space volume Vp of the dimples lying across the parting line is greater than the average space volume Vp' of the remaining dimples lying outside the parting line and/or the average Dp/Dm of the dimples lying across the parting line is greater than the average Dp/Dm of the remaining dimples lying outside the parting line wherein Dp and Dm are the depth and diameter of dimples, respectively. The golf ball is improved in symmetry in that no substantial difference occurs in flight distance between seam hitting and pole hitting.
