摘要： A two-piece golf ball includes a core and a cover having a thickness of 0.5 to 2.5 mm. The core has a hardness corresponding to a deflection in a range of 3.0 to 5.5 mm under a load of 100 kg. The cover has a Durometer D hardness 45 to 55. Dimples numbering 300 to 550 pieces are formed in the surface of the golf ball so that a dimple total volume ratio VR, which is a ratio of the total of volumes of dimple spaces under the planes surrounded by edges of the dimples in the surface of the golf ball to the total volume of a virtual ball as a result of assumption that no dimple is formed in the surface of the golf ball, is 0.85% or less. The two-piece golf ball is excellent in resilience, flight distance characteristic, controllability, and feel of hitting.

摘要： A golf ball includes a solid core, an intermediate layer, and a cover in a surface of which a plurality of dimples are formed. The solid core has a center JIS-C hardness of 50-70 and a surface JIS-C hardness of 60-80, and has a diameter of 35-40 mm. The intermediate layer is made from a material mainly containing an ionomer resin, and has a JIS-C hardness of 70-85 and a thickness of 0.5-2 mm. The cover is made from a material mainly containing an ionomer resin, and has a JIS-C hardness of 85 or more and a thickness of 0.5-2 mm. A difference in JIS-C hardness between the intermediate layer and the surface of the solid core is in a range of 15 or less. A different in JIS-C hardness between the cover and the intermediate layer is in a range of 10 or more. The hardnesses of the solid core, the intermediate layer, and the cover satisfy a relationship of (hardness gradient from intermediate layer to cover)/(hardness gradient from core center to intermediate layer)≧6. The dimples are arranged such that there is no great circle line not crossing any one of the dimples. The golf ball can exhibit a very soft hitting feel, an excellent durability, a low spin rate and a high hitting angle, and an increased carry due to a high resilience.

摘要： A wound golf ball is constructed by winding thread rubber on a center ball and enclosing with a cover. The center ball consists of a center core having a diameter of 20-37 mm and experiencing a distortion of 1-5 mm under a load of 100 kg and an enclosure layer having a Shore D hardness of 33-54 and has a diameter of 33-38 mm. The center core comprises a rubber composition comprising a base rubber, a co-crossing linking agent and a peroxide and being free of an oily substance. The cover consists of an inner layer having a Shore D hardness of 55-68 and an outer layer having a Shore D hardness of 30-58, the inner layer being harder than the outer layer by at least 5 in Shore D hardness. The ball is not only improved in spin, control, and flight distance on driver and approach shots, but also gives pleasant hitting feel with click.
