Abstract

A back recess balance weight structure for golf club heads is located on a back side of a golf club head relative to the striking face and includes a back recess body and a sealing cap. The back recess body has a back recess with a plurality of cavities formed therein. The sealing cap covers the back recess by bonding. The structure consists of simple elements. The sealing cap is made from a material of a smaller specific gravity to move the weight of the club head to the optimal position. The adhesive can absorb shock and vibration to form a tight sealing of the sealing cap and the back recess body. Thereby optimal stability and striking accuracy can be achieved during swinging of the golf club.
