摘要： PROBLEM TO BE SOLVED: To provide a golf ball which is excellent in durability while having an extremely soft hitting feeling, and can increase the carry by a low spinning, a high hitting out and a high repulsiveness. SOLUTION: This golf ball is equipped with a solid core, an intermediate layer, and a cover. Also, numerous dimples are formed on the surface of the golf ball. In such a golf ball, the center JIS-C hardness of the solid core is 50 to 70, the surface JIS-C hardness is 60 to 80, and the diameter is 35 to 40 mm. The intermediate layer is formed of an ionomer resin as the main component. Also, the JIS-C hardness of the intermediate layer is 70 to 85, and the thickness is 0.5 to 2 mm. The cover is formed of an ionomer resin as the main component. Also, the JIS-C hardness of the cover is 85 or higher, and the thickness is 0.5 to 2 mm. At the same time, the difference in the JIS-C hardness between the intermediate layer and the surface of the solid core (|the intermediate layer - the solid core surface|) is 15 or lower, and the difference in the JIS-C hardness between the cover and the intermediate layer (|the cover - the intermediate layer|) is 10 or higher. Then, each hardness of the solid core, the intermediate layer or the cover satisfies a relationship of (a hardness gradient from the intermediate layer to the cover)/(a hardness gradient from the core center to the intermediate layer)>=6. Also, the dimples are arranged in such a manner that there may be no great circle line which does not cross the dimples.

摘要： PROBLEM TO BE SOLVED: To provide a three-piece solid golf ball which does not reduce the carry at the time of a full shot by a driver or a long iron, and by which an excellent controlling property can be obtained by improving the spinning characteristics at the time of an approach shot using a short iron or the like, and in addition, a favorable linearly advancing property with an excellent rolling property on the green can be obtained, and an excellent durability wherein scratches by hitting are hard to occur can be obtained as well. SOLUTION: This three-piece solid golf ball comprises a three-layer structure of a solid core, an intermediate layer and a cover. In such a three-piece solid golf ball, the deformation amount of the solid core when a load of 100 kg is applied is 2.5 mm or higher. The cover is formed mainly of a thermoplastic polyurethane elastomer as the main material, in a manner to have the Shore D hardness of 35 to 55. Also, the moment of inertia of the overall ball comprising these three layers is 83 gcm2 or higher.

摘要： PROBLEM TO BE SOLVED: To provide a multilayer golf ball wherein a spinning performance can be reduced so that an excessive resistance against a lift during the carry of the ball, resulting in an increased carry, can be reduced, while with respect to a feeling of hitting ball, soft, comfortable and light sounds of hitting, which would not have been achieved by a conventional ball having a structure wherein flat spherical planes are layered, can be produced, and at the same time, by providing a regular polyhedral form, even if any point of the ball is hit, similar feeling of hitting, spinning performance, and carry can be obtained. SOLUTION: In the multilayer golf ball the core of which is covered with two or more cover layers, 50-500 recesses are arranged in two adjoining inner side layers of the cover layers in a regular polyhedral pattern, while a protrusion is formed on an outside layer so as to penetrate into corresponding recess.

摘要： PROBLEM TO BE SOLVED: To obtain increase a good feeling of hitting ball by an increase in carry of a ball. SOLUTION: In the multilayer golf ball, two or more cover layers are formed over a core 2, a large number of recesses are formed on the inner side layer of the two cover layers 11, which are adjacent to each other, while protrusions are formed on the outer side layer thereof so that each protrusion penetrates into corresponding recess. A great circular ridgeline 12 having the same length as the outer circumference of the inner side layer, not in contact with the recesses, is formed. At least two arcuate redgelines 13, each of which intersects the great circular ridgeline 12 at right angles and has a length of at least one- fourth the outer circumference of the inner side layer, are formed on one of semispheres 11a between a pole 14 and the above great circular ridgeline. Each ridgeline 13 is not in contact with the recesses between the great circular ridgeline 12 and a point circumferentially offset by 30 deg. from a pole, while the recesses are disposed in a region defined by the arcuate ridgelines symmetrically with respect to the arcuate redgeline 13 on each of semispherical parts divided by the great circular ridgeline 12.
