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.

Abstract: Provided is a golf club head in which the lateral moment of inertia can be increased through thickness adjustment of the sole portion. The golf club head according to the present invention includes a crown portion, a sole portion and a face portion. The sole portion includes a first thin-walled portion and a first thick-walled portion that extends from the toe side of the first thin-walled portion to the heel side of the first thin-walled portion via the back side, so as to surround the first thin-walled portion, and is thicker than the first thin-walled portion.

Abstract: A fitting method, of a shaft of a golf club, for selecting a shaft having a torque matching a golfer based on a swing of the golfer. The method includes the steps of obtaining measurement values from a sensor attached to a grip of the golf club and capable of measuring angular velocities about three axes when a golf ball is hit by the golf club; obtaining a predetermined index value for the angular velocities quantified from the measurement values; and selecting a shaft matching the golfer from among multiple shafts whose torques have been measured in advance, based on a relationship established through test-hitting performed in advance between the index value and a torque of a shaft.

Abstract: A fitting method of a shaft of a golf club for selecting a shaft matching a golfer based on a swing of the golfer. The method includes the steps of obtaining measurement values from a sensor attached to a grip of a golf club; determining address, top, and impact of a swing from the measurement values; and selecting a shaft that matches a golfer through a usage of the swing characteristic amounts and values.

Abstract: A golf swing analysis apparatus for analyzing a swing action of a golf club is provided. The golf swing analysis apparatus comprises an acquisition unit configured to acquire a measurement value obtained by measuring the swing action using a measurement device; a grip behavior derivation unit configured to derive a behavior of a grip of the golf club that occurs during the swing action, based on the measurement value; and a shoulder behavior derivation unit configured to derive a behavior of a pseudo shoulder of a golfer that occurs during the swing action, based on the behavior of the grip.
