  As the constituent material of the first half body 10, it is preferable to use a metal or alloy having a relatively low specific gravity such as an aluminum alloy, titanium, or titanium alloy, but is not limited thereto. Although it is preferable to use stainless steel or a copper alloy (beryllium copper, bronze, etc.) for the latter half body 20, it is not limited to this. In addition, if an aluminum alloy, titanium alloy, or the like is oxidized and colored to have different colors in the first half and the second half, the range of visual design will be expanded. If the bolt 13 is made of a light alloy (for example, an aluminum alloy having a specific gravity of 2.7), the head weight can be reduced. However, the sweet area may be expanded in the toe-heel direction by using bolts 13 made of high specific polymerized gold (for example, a tungsten alloy having a specific gravity of 10 to 12).

The synthetic resin constituting the insert 30 is polyurethane, nylon, polyester, polycarbonate, etc., the rubber is silicon rubber, chloroprene rubber, nitrile rubber, natural rubber, styrene butadiene rubber, etc., and the elastomer is styrene elastomer, urethane elastomer, Ethylene elastomers, polyester elastomers, olefin elastomers, amide elastomers and the like are suitable.
In addition, inorganic fillers such as calcium carbonate, silicon dioxide, clay, and zeolite may be added to these materials, thereby reducing sink marks during molding.
A foaming agent may be used. By making the resin into two layers as shown in the figure, it is possible to reduce the thickness of the resin on the face side and to prevent the occurrence of sink marks.
Moreover, it is preferable to mix | blend a resin and an elastomer with a ultraviolet absorber and a light stabilizer. Moreover, you may mix | blend an anti-aging agent. In particular, diphenylamine-based, p-phenylenediamine-based, hydroquinone derivatives, and phosphite-based anti-aging agents are preferable because some of them have little contamination. Moreover, in order to color, you may mix | blend a pigment etc. suitably.

  The hardness of the elastomer or rubber used for the insert 30 is preferably 30 to 70 ° with a JIS D hardness meter.

  1 to 4, the score line is not shown for the sake of clarity, but the score line 33 is provided on the front surface of the second insert 32 as shown in FIG. . However, this score line may not be provided.
