摘要： A golf club head according to this invention includes a hollow head body, cylindrical body, weight member, and fixing member. The hollow head body has a projection formed along the periphery of the sole, a recess formed inside the projection, and an opening formed in the projection so as to extend from the toe side to the back side. The cylindrical body is provided in the recess of the head body, and includes its one end which engages with the inner wall of the projection on the heel side, and its other end which extends to the vicinity of the opening and can move along the opening. The weight member is retractably, detachably inserted in the cylindrical body. The fixing member is a detachable member which fixes the other end of the cylindrical body onto the projection.

摘要： A golf club shaft that has a flexural rigidity distribution allows a user to easily adjust swing timing even when a golf club using the golf club shaft is long. The golf club shaft comprises a section, wherein the flexural rigidity EI of the shaft monotonically increases in the section from the point 500 mm to the point 800 mm, wherein &Dgr;1/&Dgr;2 is at least about 1.5 where &Dgr;1 is the rate of change of the flexural rigidity EI of the shaft between points 500 mm and 600 mm from the tip end, and &Dgr;2 is the rate of change of the flexural rigidity EI between points 700 mm and 800 mm from the tip end, and wherein the flexural rigidity EI at a point 750 mm from the tip end is at least about 4.1×106 kgf*mm2.

摘要： PROBLEM TO BE SOLVED: To provide a putter head prevents a ball from sliding over a green while maintaining both of golfers' preferred hitting feel and roll of the ball. SOLUTION: A face insert 20 fitted in a face of the putter head has an outer layer 22 which serves as a ball-hitting surface and an inner layer 24 which is located on an inner side of a head body. A smash factor of a second polymer material forming the inner layer 24 is greater than a smash factor of a first polymer material forming the outer layer 22. Two types of groove, group 4 of a first groove group and grooves 5 of a second groove group are formed in an external surface 3 of the outer layer 22. The grooves 4 of the first groove group is 0.5 to 1.52 mm wide and 0.25 to 0.5 mm deep and the grooves 5 of the second groove group is 0.1 to 0.5 mm wide and 0.05 to 0.1 mm deep. Groove spacing L between adjacent grooves 4 of the first groove group is 0.8 to 1.5 mm, and one or more grooves 5 of the second groove group are placed between the grooves 4 of the first groove group.
