MULTIPIECE SOLID GOLF BALL

摘要

PROBLEM TO BE SOLVED: To make it possible to obtain a good trajectory, to increase carry at the time of a driver shot, to obtain an adequate spin quantity at the time of an approach shot and to obtain good controllability and an excellent ball hitting feel and durability. SOLUTION: The deformation quantity at the time of loading with 100 kg of the solid core of the multipiece solid golf ball consisting of the solid core and a cover of a two-layered structure consisting of an inside layer and outside layer covering the solid core is 3 to 7 mm. The inside layer cover described above has Shore D hardness of 25 to 58 and a thickness of 0.5 to 1.4 mm. The outside layer has Shore D hardness of 30 to 62 and a thickness of 1.2 to 2.3 mm. The ratio (thickness of the outside layer cover/thickness of the inside layer cover) of the thickness of the outside layer cover and the thickness of the inside layer cover is 1.1 to 4.6.
