Abstract

A golf club head which comprises a metallic hollow body having a sole, a crown, a heel, a toe, a rear wall, and a striking face. A single web is secured to and subtends downwardly from the inner surface of the crown, with the web extending perpendicularly from the inner surface of the striking face and terminating short of the inner surface of the rear wall, the depth of the web being greatest at the inner surface of the striking face. The web is located along the transverse centerline of the club head. This web configuration substantially eliminates crown vibrations in oversized metal woods.

Claims
