Golf club head
First Claim
1. A golf club head comprisinga main body provided with at least two holes separately and detachable parts attached to said holes,the main body comprisinga face portion whose front face defines a club face for hitting a ball,a sole portion extending from a lower edge of the club face toward a back face of the club head anda turnup wall turned up at a rear side of the sole portion so as to form a gap behind the face portion,the holes being provided in the sole portion and/or the turnup wall, and being through holes passing through the sole portion and/or the turnup wall, andthe detachable parts including a weight member attached to one of the holes and a damper attached to another of the holes,the weight member having a specific gravity larger than the specific gravity of the main body,the damper having a specific gravity different from the specific gravity of the weight member and made of elastic material at least partially for absorbing a vibration of the main body, and the damper having a protruding portion extending from the hole into the gap, andsaid holes having the substantially identical shapes so that the position of each of the detachable parts can be exchanged.
