Abstract: An iron type head body comprises: a material body 13 made from a forgeable metal; and a disparate metallic member 12 made from a metal having nearly equal or smaller specific gravity than the material body 13, and different constituents. By providing the disparate metallic member 12 inside the upper portion of the head body not adjacent to the sole, the head can be lightened. Moreover, by confining the disparate metallic member 12 in the portion upside of the sole 4 not adjacent to the sole 5, the head body 11 can be hypobaric, while the C.G. of the head 2 can be lowered entirely in addition to being lightened.

Abstract: A method for manufacturing a golf club head with a disparate metallic material provided on a hosel side of the head, which can improve degree of freedom in the design of a head. A head body is made up of a columnar material body 13 made from a forgeable metallic material such as copper and a disparate metallic member 12 as an axial member. The disparate metallic member 12 has its proximal end 12A inserted into a bore 14 formed along a center of axis of the material body 13, while its distal end 12B protruded in the axial direction X. The material body 13 is placed on a lower die 22 which is formed with a mold 21 defining a contour of the head body 11, and then an upper die is pressed thereto. Thus, hot forging process is carried out to form a golf club head.

A golf club construction is obtained wherein, in a driver club head (1) comprising a face section 4 having a striking surface, a sole section (3) forming the bottom, a crown section (2) forming the top and a back section (3a) forming the back portion, when the loft angle is small, the amount of backspin is reduced and performance is maintained, and even when the loft angle is large, the amount of backspin is reduced and a good carry distance is achieved. For this purpose, the crown section (2) is improved, with the provision of a weight (8) on the inside surface thereof nearer to the face section than the center of the surface

Abstract: Provided is a fixing sleeve making it possible to reduce the surface roughness of the inner circumferential surface of the fixing sleeve by spinning, and a method for manufacturing the fixing sleeve. The spinning is performed by moving rollers, in the axial direction of a cup-shaped tubular body and, at the same time, a burnishing tool (spherical tool) is pressed against the outer circumferential surface of the cup-shaped tubular body after the spinning, and the burnishing tool is moved in the same direction as the rollers. The cup-shaped tubular body is plastically deformed in the axial direction of the cup-shaped tubular body, reduced in wall thickness, and elongated in the axial direction.

Abstract: A golf club having an increased moment of inertia and improved ball-hitting directionality is provided. A metal hollow golf club head comprises: a face portion; a crown portion; and a sole portion, and when the golf club has a lie angle of 60° with its club head volume being within 470 cm3, a moment of inertia about the axial line centered on the plumb line passing through the golf club head center of gravity is 5000 to 6000 g-cm2. In order to increase the moment of inertia, the thickness of the center portion of the crown portion is reduced by chemical etching, and a mass, including the portion of mass reduction, is positioned in the sole portion on the side of the toe portion; moreover, the separation distance from the center of gravity to the mass is increased.
