Patent ID: 7108615

Claim:
A golf ball composed of an elastic solid core and a resin cover enclosing said core and having a number of dimples in the surface thereof, which is characterized in that said elastic solid core has resilience such that the deformation is 3.0 to 5.0 mm when the load is increased from 98 N (10 kgf) to 1275 N (130 kgf), said cover has a gage of 1.2 to 2.1 mm and a Shore D hardness of 60 to 75, and said dimples two or more different patterns, with their number amounting to 250 to 370, and wherein said dimples are so formed as to satisfy the following equation: {( A−B )/ A}× 100=1.1 to 1.6% where, A denotes the hypothetical volume of the golf ball which is calculated on the assumption that the golf ball is a true sphere without dimples in its surface, and B denotes the actual volume of the golf ball.
