    摘要: A golf club head is disclosed, which is capable of setting a head center of gravity projected on a face surface in the vicinity of a face center even when a head thickness excluding a face portion is made uniform or a head volume is increased to a maximum. In this golf club head, in a three-dimensional coordinate axis with a face center set as an origin, a coordinate value of each most bulged position in a head body is specified, and a shape of the head body is brought close to that of symmetry in an upper-lower direction and, more preferably, to that of symmetry in upper-lower and right-left directions.

    摘要: Disclosed is a golf club set having harmonized golf club performance among the club numbers. In the golf club set, for at least three golf clubs, a ratio or a sum of a frequency, the frequency being measured by vibrating a tip portion of a golf club shaft constituting each of the golf clubs, and a frequency, the frequency being measured by vibrating a rear end portion of the golf club shaft, is determined in relation with order of the club number.

    摘要: The golf club head (14) of the present invention has a face portion (24) for striking a golf ball, a crown portion (18) connected to the face portion (24), and a sole portion (22) connected to the face portion (24). The ratio of either lower of a first equivalent rigidity of a crown member (18) and a second equivalent rigidity of a sole member (22) to the higher is equal to or less than 0.75. The present invention provides a golf club (10) provided with the hollow golf club head (14) capable of increasing the carry of a golf ball based on a technique for increasing the carry of a golf ball other than conventional ones such as adjustment of the loft angle and reduction in the thickness of the striking surface, and provides a method of designing such a hollow golf club head as well.
