摘要： A golf ball 2 includes a core 4 and a cover 6. An amount of compressive deformation Df of the core 4 is equal to or greater than 4.1 mm. A nominal thickness T of the cover 6 is equal to or less than 1.70 mm. The golf ball 2 has a plurality of dimples 8 on a surface thereof. A value V calculated by the following mathematical formula is equal to or less than 290. V = N * So / Bb In the mathematical formula, N represents a total number of the dimples 8, So represents a ratio of a total area of all the dimples 8 relative to a surface area of a phantom sphere of the golf ball 2, and Bb represents an average (mm) of thicknesses B of the cover 6 immediately below deepest points of the dimples 8.

摘要： [Object] To provide a method for easily increasing the internal pressure of a hollow ball in a practical time. [Solution] A method for increasing the internal pressure of a hollow ball according to the present invention includes the steps of (1) putting a hollow ball 18 including an outer shell and a space surrounded by the outer shell, into a housing portion 4; (2) filling the housing portion 4 with a gas which is more excellent in permeability relative to the outer shell than oxygen gas and nitrogen gas; and (3) causing the gas to pass through the outer shell. When the outer shell contains natural rubber, preferably, in the step (2), the housing portion is filled with a gas having a permeability coefficient of 20 × 10 -17 m 4 /(N€¢s) at 25°C for the natural rubber. Preferably, in the step (2), the housing portion is filled with carbon dioxide gas.

摘要： [Object] To provide a method for storing a hollow ball easily at low cost. [Solution] A method for storing a hollow ball according to the present invention includes the steps of: (1) putting a hollow ball 4 including an outer shell and a space surrounded by the outer shell, into a housing portion 6; (2) decreasing a temperature of the hollow ball 4 to a temperature lower than a temperature of external air; and (3) storing the hollow ball in a state where the temperature of the hollow ball 4 is made lower than the temperature of the external air. Preferably, the storing method further includes the step of (4) increasing the temperature of the hollow ball 4 after the step (3). Preferably, in the step (4), the temperature of the hollow ball 4 is increased to a temperature exceeding a dew point of the external air.
