<p>PURPOSE:To reduce the disturbance of the air flow behind a head, reduce the air resistance of a swing, and increase the speed of the swing by providing vortex occurrence preventing dimples behind the peeling point of the air flow generated by the swing on the surface of the wood type golf club head. CONSTITUTION:Dimples 7 are provided behind the peeling point of the air flow of a wood type golf club head H, and the disturbance of the air flow generated behind the head H is reduced by the dimples 7. The dimples 7 are preferably provided behind the peeling point of a top face 3. The vortex occurrence preventing effect when the dimples 7 are provided behind the peeling point of the lower face is smaller than the effect of the dimples 7 provided behind the peeling point of the top face 3. The vortex occurrence behind the peeling point is mitigated, the air resistance of a swing is reduced, the speed of the swing can be improved, and flight distance of a ball can be increased.</p> |
