Abstract
In construction of a wood type golf club head, its main body made of a material unsuited for plastic deformation such as FRP and its and hosel made of a material suited for plastic deformation such as metal are separably coupled to each other. Subtle adjustment of ball striking characteristics such as loft and lie angles can be practiced quite freely independently of the material used for the main body.
