摘要： A practice golf ball having a multiplicity of dimples formed in its surface has a weight of 46.5-49.0 grams and undergoes a distortion of 2.5-4.0 mm under a constant load of 100 kg. A percent dimple volume Vr is in the range of 0.7%.ltoreq.Vr.ltoreq.1.1% wherein the percent dimple volume Vr is the sum of the volumes of the entire dimples divided by the volume of a phantom sphere given on the assumption that the ball surface is free of dimples. The ball offers a good feel upon shots, follows a low trajectory without substantial shortage of a flight distance, and is thus suited for use in urban golf practice pits of limited space.

摘要： A practice golf ball having a multiplicity of dimples formed in its surface has a weight of 46.5-49.0 grams and undergoes a distortion of 2.5-4.0 mm under a constant load of 100 kg. Those dimples having a diameter/depth (Dm/Dp) ratio between 10/1 and 15/1 occupy at least 80% of the total number of dimples. The ball offers a good feel upon shots, follows a low trajectory without substantial shortage of a flight distance, and is thus suited for use in urban golf practice pits of limited space.

摘要： A golf ball comprising a core, a cover inner layer and a cover outer layer has a plurality of dimples on the surface. The JIS-C hardness of the ball decreases successively within specific ranges from the cover outer layer to the cover inner layer to the core surface, but is substantially uniform within a central portion of the core. The dimples are of at least three types having different diameters and have an average diameter of 3.3-4.0 mm and an average depth of 0.11-0.17 mm, with the ratio of average diameter to average depth being from 25 to 33. The total number of dimples is from 380 to 450. The ball exhibits a relatively large deflection and a high resilience on impact which enable it to achieve an improved distance, as well as a good feel.

摘要： In a two-piece solid golf ball comprising a solid core and a cover having a number of dimples, the solid core has such a distribution of hardness on a JIS-C hardness scale that a surface hardness is 70-85 degrees and a center hardness is lower than the surface hardness by 8-20 degrees, and the hardness within 5 mm inside the core surface is up to 8 degrees lower than the surface hardness. The cover has a hardness of 75-90 degrees on a JIS-C hardness scale which is higher than the surface hardness of the core by 1-15 degrees and a gage of 1.5-1.95 mm. The number of dimples is 360-450. Since the hardness distribution of the core and cover, the gage of the cover, and the number of dimples are optimized, the ball is improved in flight distance, controllability and hitting feel.

The ball satisfies 1.10.ltoreq.A/B.ltoreq.1.60 wherein A and B are distortions (mm) of the solid core and the ball under a load of 100 kg, respectively. The ball will follow an adequately high trajectory to ensure an increased flying distance when ordinary golfers with a head speed of about 40 m/sec. hit it with drivers and especially with long irons. The ball also offers a soft feel on hitting.
