Patent ID: 7086967

Claim:
A golf ball comprising a core, an intermediate layer enclosing the core to form a sphere, and a cover enclosing the intermediate layer, wherein each component has a Shore D hardness, a Deflection amount, an initial velocity (in m/s) and a thickness (in mm), the Deflection amount being defined as an amount of deflection (in mm) under load of a spherical body incurred when the load is increased from an initial value of 98 N (10 kgf) to a final value of 1275 N (130 kgf), and the ball satisfies the following requirements (1) to (5): (1) (Shore D hardness of the cover)−(Shore D hardness of the intermediate layer)>0, (2) (initial velocity of the sphere)−(initial velocity of the core)>0, (3) 0.90≦(Deflection amount of the sphere)/(Deflection amount of the core)≦1.00, and (4) the total of the thickness of the intermediate layer and the thickness of the cover is up to 3.0 mm (5) 0.85≦(Deflection amount of the golf ball)/(Deflection amount of the sphere)≦0.95.
