DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a golf club head, and more particularly to a golf club head that uses a light alloy such as a town or aluminum as a casing. [Prior Art] Magnesium and other light alloys are formed with high-foll heads, which are light in weight, and each easy to design a super-large and low-centered club head, especially the shock absorption of the alloy, as the head The shell has its own advantages, but magnesium bismuth ^ = car = ' is not suitable as a hitting surface, so the hitting surface must be made of elastic = material such as titanium alloy or unsense, but magnesium or alloy :, 'Therefore, the impact surface of titanium alloy or steel can not be hard welded with the assembly of the town or Shao Eri, nor can it be connected by ordinary welding. The material of the joint is not strong enough. The effect is poor. 15 [Summary of the Invention] The main purpose of the sample day is to provide a golf club head that can handle the problem of the titanium alloy or the stainless steel hitting surface and the magnesium residual alloy shell. X σ 2. IP, for the purpose of the invention, according to the present invention, a golf club includes a front side shell member and a rear side shell member, which are mutually joined to form a rod: a body 'in which · front side shell member It is made of titanium alloy or aging steel or steel with better elasticity. It has a ball striking surface and extends from the ball 2 to a ring-shaped crotch. The whole cup is in the shape of a cup. The outer end of the part has an inlay portion, and the distance between the crotch portion from the ball striking surface to the outer end of the crotch portion is 4200819172 or greater than 8 mm, and the thickness of the crotch portion is equal to or less than 2 mm; The side shell member is made of a light-weight metal such as magnesium alloy or aluminum alloy, and has a deep cup shape as a whole, and has an engaging portion at the open end edge thereof for engaging with the front side shell member. The two heads are fitted to each other; the neck of the head housing is disposed on the rear 5 side shell member. [Embodiment] The following two embodiments are described with reference to the following figures: As shown in the figure, the golf club head (10) of the first embodiment of the present invention is composed of a front side shell member (20) and a rear side shell. The component (30) is composed of: the front side shell member is made of a metal having a better elasticity such as titanium alloy or stainless steel or aging steel, and has a ball striking surface (21) and a self-hitting surface ( 21) A ring-shaped crotch portion (22) is extended backward, and has a cup shape as a whole. An engaging portion (23) is provided at the outer end of the crotch portion (22), and the crotch portion (22) is self-hitting ( 21) The distance W from the outer end of the crotch portion 15 is equal to or greater than 8 mm, and the thickness D of the crotch portion (22) is equal to or less than 2 mm. In the present embodiment, w is 1 mm, and d is 1.5 mm. The rear side assembly (30) is made of a light weight metal such as a magnesium alloy or a smelting alloy, and has a deep cup shape as a whole, and an engaging portion 2 〇 (31) is provided at an opening end edge thereof for Engaging with the engaging portion (23) of the front side case member (20). The engaging portion (23) of the front side shell member (20) of the embodiment has a convex portion, and the thickness s between the outer side wall surface of the engaging portion (31) of the rear side shell member (31) to the groove groove wall is 3 is shy below, the thickness of this embodiment S is L5 mm. “As shown in the fourth figure, the front side shell member (2〇) is extended to the rear of the bottom surface 5 200819172 to extend a longer bottom portion (24), and the rear side shell member (30) corresponds to the bottom portion (24). The shape is provided with a notch or a groove, thereby forming a protective metal layer on the bottom surface of the head casing (10). That is to say, the central portion of the head casing (10) at the bottom surface may be the bottom portion of the front side casing member (24) Formed separately, or the rear side shell member (30) is provided with a concave groove 5 at this portion, and the bottom portion (24) of the front side shell member is attached to the groove position to form an upper and lower two-layer structure. The neck portion (11) of the body (10) is integrally provided on the rear side shell member (30), and has a shock absorbing effect. An adhesive agent such as a ring 1 is disposed between the front side shell member (20) and the rear side shell member (30). The silicone resin is fixedly attached. The head housing (10) of the present invention is provided on the rear side shell member (30) because the neck portion (11) is pressed. Therefore, the strong impact stress subjected to the impact of the ball will force the front side casing ( 20) The back side case member (30) is pressed further, and because the two portions are engaged with each other by the convex portion (23) and the groove (31), the epoxy resin is allowed to be bonded without cracking and falling off 15 Danger. The invention The front side shell member (2〇) is made of a relatively elastic metal such as titanium alloy or stainless steel, and the distance W of the crotch portion must be 8 mm or more, preferably 10 mm, and the thickness D must be 2 mm or less, preferably 1.2 to 1.5 mm, whereby the crotch portion (22) is more flexible, so that when the ball striking face (21) is subjected to a strong impact stress, the crotch portion (22) The flexing k-shape can be generated in the same direction, so that the impact stress and the deformation amount at the engaging portion (23) can be reduced, so that the engaging portion of the rear side shell member (3〇) is subjected to less stress, so the rear side The wall thickness s of the engaging portion of the shell member (30) can be appropriately thinned, so that the weight can be reduced, and the rear side shell member (30) can be prevented from being thick and thick in the top cover (13) of the head shell (1). 6 200819172 As shown in the fifth figure, is a cross-sectional view of the head housing (40) according to the second embodiment of the present invention in the same direction as the line 2-2 in the first drawing. (50) is composed of a top member (60) and a bottom member (70), wherein the top member (60) is made of lightweight shock absorbing metal such as magnesium or aluminum alloy, and the bottom member (70) is Non-mineral steel It is made of heavier materials such as Chin or Crane, recorded, and has the effect of wear resistance and counterweight, while the head and neck are integrally formed on the top member. 7 200819172 [Simplified illustration] The first figure is the present invention 2 is a cross-sectional view of the structure taken along line 2-2 in the first figure. The third figure is an enlarged view of the circled portion in the second figure. The fifth view is a cross-sectional view of the structure of the second embodiment of the present invention.
