Abstract

A weight adjusting structure of a golf club head comprises a 360-degree rotatable rotary table installed in a body of a golf club head, wherein the rotary table is combined with an incomplete annular weight block at a peripheral portion on an arbitrary side thereof, so that the rotary table and the weight block form a rotary table assembly whose weight orientation can be adjusted. The weighted rotary table assembly installed in the body of the golf club head can be used to adjust a distribution of different weights around 360 degrees, whereby a preferred location of the club head'"'"'s gravity center can be set according to a golfer'"'"'s swing posture and a location of the club head'"'"'s gravity center the golfer is used to.

Claims
