Golf ball
Abstract:
Disclosed is a golf ball in which a plurality of dimples is arranged. The golf ball includes first dimples having the largest diameter and second dimples having the second largest diameter arranged on the surface of the golf ball divided into a spherical rhombic dodecahedron, the first dimples are arranged in an LF region of a radius of π/10 radian ±10% around a first apex of the spherical rhombic dodecahedron, shared jointly by 4 spherical rhombi, and the second dimples are arranged in an LS region of a radius of π/20 radian ±10% around a second apex of the spherical rhombic dodecahedron, shared jointly by 3 spherical rhombi. Thereby, air flow and pressure drag are uniformized in all of spherical polygons and thus, a carry distance of the golf ball may be improved.
