    摘要: A half shell having a top part thickness of 65% or greater and 95% or less and a side part thickness of 100% or greater and 120% or less of the nominal thickness T of the cover is formed. Next, the core 4 composed of the center and the mid layer is fitted to two pieces of the half shell 46. Next, the core 4 and the half shell 46 are placed into a mold 32. Next, the mold 32 is clamped at a speed of 0.5 mm/sec or greater and 2.0 mm/sec or less. The thermoplastic resin composition of the half shell 46 is heated while being compressed in the spherical cavity to result in flow. This resin composition is hardened to give a cover having a thickness of 0.1 mm or greater and 0.8 mm or less. Dimples are formed on the cover by way of pimples 40. Recessed parts are formed on the mid layer by way of the pimples 40.

    摘要: A plurality of golf clubs having mutually different flex point rates of a shaft is prepared. A subject hits a golf ball with one reference club included in the golf clubs. A face angle of the golf club immediately before hitting is measured by an apparatus 10. A recommended flex point rate P is calculated by substituting, into the following mathematical expression, the face angle Q and the flex point rate R of the reference club: P=0.8648·Q+R−5.033 A golf club having a shaft whose difference between the flex point rate and the recommended flex point rate P is within a predetermined range is selected as a recommended club. The subject hits a golf ball with the recommended club. The apparatus 10 measures a speed, a launch angle, a backspin speed, a sidespin speed, and a deflection angle of the golf ball.
