Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of ruggedness on the surface and to suppress the cooling defects at the hardening portion in a hardness technique by using a high frequency induction heating for a thin-thickness conductive pipe material such as a steel-made golf shaft. SOLUTION: The thin-thickness pipe-shaped golf shaft W is lowered into a heating coil 210 to be subjected to the high frequency heating, and then the golf shaft W is dipped into a hardening oil 310 to be subjected to cooling, thereby hardning the golf shaft W. In that case, inert gas is supplied to the inside of the golf shaft W to prevent the hardening coil 310 from entering into the inner part of the golf shaft W. In this way, the hardening oil 310 is suppressed from boiling in the inner part of the golf shaft W, thereby preventing the blowing-up of the hardening oil 310 due to the boiling. Therefore, the uneven cooling caused by the blowing-up of the hardening oil 310 is prevented. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To securely fix a grip to a shaft body, to achieve differentiation of appearance, to improve flexural strength, flat strength, vibration damping characteristics or the like of a grip part, and to obtain a lightweight golf club shaft. SOLUTION: Reticulated mesh sheet material 6 (a mesh member) is interposed between the shaft body 5 and the grip 3. Alternatively, the mesh sheet material 6 (an exposed part 6A) is exposed from the grip 3 for visually recognizing from outside so as to achieve differentiation of the appearance. On a side of a grip fitting end part 7 of the shaft body 5 formed of steel, the mesh sheet material 6 formed of CFRP, carbon fiber reinforced plastic having meshes or other uneven shapes is circumferentially fixed to an outer circumferential side, so that the grip 3 is fixed to the outer circumferential side of the mesh sheet material 6.

Abstract: PROBLEM TO BE SOLVED: To provide a lightweight golf club shaft having high strength and high toughness. SOLUTION: The steel golf club shaft assuming the shape of a hollow pipe has an inclined structure in which the distribution of the content of a thicknesswise retained austenite is increased toward the outside surface. The distribution and/or crystal grain size of the longitudinally retained austenite is adjusted to secure strength and toughness in a golf club shaft region to which a maximum stress is applied when the shaft is bent. This provides a steel golf club shaft aiming for being a thin-walled and lightweight type. COPYRIGHT: (C)2009,JPO&INPIT
