<p>PURPOSE:To extremely restrain deviation of a ball impact face at the time of swinging to easily and surely control a ball in the aimed direction by providing a golf club with a weight part for weight adjustment which connects a shaft member and neck shaft member to each other in a mutually offset state. CONSTITUTION:A neck shaft 11 is extended from one end side of a head member 12 and an upper end part of the neck shaft 11 and a lower end part of a shaft 2 are respectively connected to a nearly rectangular parallelopiped shape weight member 10 with a span H in the nearly orthogonal direction to an impact face 6. Since the weight member 10 is placed in the vicinity of the shaft 2, when a mass of the head part is fixed, the weight member operates to decrease moment of inertia around an axis of the shaft 2 and therefore ball hitting in a state of holding the impact face 6 orthogonally to the swing direction becomes easy. Also, since a center of gravity of the head part is brought near to the axis of the shaft 2, swing feeling is enhanced.</p> |
