Golf ball

摘要

The surface of a golf ball 2 is divided by four comparting great circles CG into six spherical quadrangles Ss and eight spherical triangles St. The eight spherical triangles St are composed of four first spherical triangles St1 and four second spherical triangles St2. Dimple patterns of the six spherical quadrangles Ss are the same. Dimple patterns of the four first spherical triangles St1 are the same. Dimple patterns of the four second spherical triangles St2 are the same. The dimple pattern of each first spherical triangle St1 is different from the dimple pattern of each second spherical triangle St2. The comparting great circles CG are obtained by projecting the 24 sides of a cuboctahedron inscribed in a phantom sphere of the golf ball 2 on the surface of the phantom sphere.

1. A golf ball having a large number of dimples on a surface thereof, wherein when a surface of a phantom sphere of the golf ball is divided into six spherical quadrangles and eight spherical triangles by four comparting great circles which are formed by projecting sides of a cuboctahedron inscribed in the phantom sphere on the surface of the phantom sphere, the eight spherical triangles include four spherical triangles each having a first dimple pattern, and four spherical triangles each having a second dimple pattern different from the first dimple pattern.
