摘要: Golf ball 2 has a northern hemisphere N above the equatorial line 16, and a southern hemisphere S below the equatorial line 16. Each of the northern hemisphere N and the southern hemisphere S has a pole vicinity region 18, an equator vicinity region 20 and a coordination region 22. The pole vicinity region 18, the equator vicinity region 20 and the coordination region 22 have numerous dimples 8, respectively. The dimple pattern in the pole vicinity region 18 includes multiple units that are rotationally symmetric each other centered on the pole point P. The dimple pattern in the equator vicinity region 20 includes multiple units that are rotationally symmetric each other centered on the pole point P. Number of the units in the pole vicinity region 18 is different from number of the units in the equator vicinity region 20. The dimple pattern in the coordination region 22 cannot be comparted into multiple units that are rotationally symmetric each other centered on the pole point P.

摘要: Two-tiered dimples 8 of a golf ball have a first recessed part X and a second recessed part Y. The first recessed part X substantially forms a part of a spherical shape. The first recessed part X includes a first opening 14, a side wall curved face 16 and a flat face 18. The second recessed part Y is substantially a regular quadrangular pyramid. This second recessed part Y includes a second opening 20, a slope 22 and a bottom face 24. The second opening 20 is a regular tetragon. The first recessed part X improves aerodynamic symmetry of the golf ball. The second recessed part Y improves a dimple effect. Proportion of the number of the two-tiered dimples 8 to total number of the dimples is equal to or greater than 70%.

摘要: A golf ball mold comprises an upper portion (1) and a lower portion (3). A large number of projections (7) for dimple formation are provided on a cavity surface (5) of each of the upperportion (1) and the lower portion (3). The joining surface of the upper portion (1) and the lower portion (3) has a concavo-convex shape. In each of the upper portion (1) and the lower portion (3), each of the numbers of convex and concave sections is three to five. Each of the convex sections has two to eight projections (7) on a first line from the joining surface. At least one of the projections (7) on the first line from the joining surface in each of the convex sections is constituted such that an equation (I) is established: R×0.8≦L≦R×1.2 (I). In the equation (I), R represents a radius of the projection (7) and L represents a linear distance in a vertical direction between a center of the projection (7) and the joining surface.
