Abstract: Provided is a fitting apparatus that accurately and objectively determines an optimal swingability index, which is a swingability index of a golf club suited to a golfer. The fitting apparatus is provided with an acquisition unit, a calculation unit, and a determination unit. The acquisition unit acquires a measurement value obtained by measuring a swing action of a test club by the golfer with a measurement device. The calculation unit calculates a swing index indicating a feature amount of the swing action, based on the measurement value. The determination unit determines the optimal swingability index, according to a magnitude of the swing index.

Ige is 2870 (kg·cm2) or greater and less than 2920 (kg·cm2). Isw/Ige is equal to or less than 2.46. 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)

Abstract: An iron-type golf club head comprises a head main body and a face plate attached thereto. The face plate has an annular outer edge portion fixed to the head main body, and a noncontact portion not contacting with the head main body. The noncontact portion includes a first thin part and a second thin part having a thickness less than that of the outer edge portion. The first thin part extends in a peripheral side along the upper edge, the toe-side edge and the lower edge of the face plate. The second thin part is formed to have a thickness less than that of the first thin part. The area of the first thin part is 10% to 35% of the area of the noncontact portion. The area of the second thin part is 65% to 90% of the area of the noncontact portion.

Abstract: A head 2 includes a head body h1 and a neck part n1. The head body h1 and the neck part n1 are joined. The head body h1 has a body side joint surface s1 and a first recessed part opened in the body side joint surface s1. A space v1 is formed by the first recessed part r1. The neck part n1 has a neck side joint surface brought into surface contact with the body side joint surface s1 and a shaft hole 14. An abutted boundary surface Pt passes through a vicinity ad1 of a head height lowest point. When a plane perpendicular to an axis line z of the shaft hole 14 is defined as PL, and an angle between the plane PL and the abutted boundary surface Pt is θ degree, the angle θ is a plus value.

Abstract: 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 2820 (kg·cm2) or greater and less than 2870 (kg·cm2). Isw/Ige is equal to or less than 2.42. 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).

Abstract: An iron-type golf club head has a face for hitting a ball, a sole extending backward from the lower edge of the face and extending in the toe-heel direction of the head so as to define the bottom surface of the club head, and a hosel extending upward in a heel-side of the face and provided with a shaft inserting hole. The club head is composed of a head main body including the face, and a weight member having a specific gravity larger than that of the head main body and fixed to the head main body. The weight member integrally includes a first part extending in the toe-heel direction in the sole, and a second part constituting at least substantial portion of the hosel.
