Document Type and Number:
Japanese Patent JP4816847
Kind Code:
B2
Abstract:
A multi-piece solid golf ball includes an elastic solid core, a resinous intermediate layer and a resinous cover. When subjected to a load of 1274 N (130 kgf) from an initial load of 98 N (10 kgf), the solid core undergoes a deformation A, a sphere consisting of the solid core and the intermediate layer undergoes a deformation B, and the golf ball undergoes a deformation C, all expressed in millimeter, which satisfy the relationship: 1.14<=A/B<=1.30 and 1.05<=B/C<=1.16. This combination of features provides the ball with qualities desired by professional golfers and skilled amateurs, including spin and flight performances.
