GOLF CLUB

摘要

A golf club 2 includes a head 4, a shaft 6, and a grip 8. A club inertia moment about a swing axis is defined as Isw. A club inertia moment about a grip end is defined as Ige. Ige is 2920 (kg·cm2) or greater and less than 2970 (kg·cm2). Isw/Ige is equal to or less than 2.48. A club weight is defined as Wc (kg), an axial direction distance from the grip end to a center of gravity of the club is defined as Lc (cm), and a club inertia moment about the center of gravity of the club is defined as Ic (kg·cm2). Isw is calculated by Equation (1) below. Ige is calculated by Equation (2) below.;Isw=Wc×(Lc+60)2+Ic  (1);Ige=Wc×(Lc)2+Ic  (2)

1. A golf club comprising:
a head, a shaft, and a grip, wherein: if a club inertia moment about a swing axis is defined as Isw (kg·cm2), and a club inertia moment about a grip end is defined as Ige (kg·cm2), the inertia moment Ige is 2920 (kg·cm2) or greater and less than 2970 (kg·cm2), and Isw/Ige is equal to or less than 2.48; and if a club weight is defined as Wc (kg), an axial direction distance from the grip end to a center of gravity of the club is defined as Lc (cm), and a club inertia moment about the center of gravity of the club is defined as Ic (kg·cm2), the inertia moment Isw (kg·cm2) is calculated by Equation (1) below, and the inertia moment Ige (kg·cm2) is calculated by Equation (2) below.
Isw=Wc×(Lc+60)2+Ic  (1)Ige=Wc×(Lc)2+Ic  (2)
