The body includes a crown in which at least one opening is defined. A perimeter delimiting the opening includes a stepped portion. The transparent cover is securely mounted to the opening of the crown. The transparent cover is made of a transparent material having a specific gravity smaller than 1.5 g/cm3 for reducing a weight of the crown of the golf club head and for shifting a center of gravity of the golf club head downward and rearward.

Abstract: A golf club head includes a body having at least one recessed portion for securely receiving at least one weight member. The weight member includes a lid with a plurality of protrusions respectively received in receiving portions of the recessed portion. At least one of the protrusions has a weight different from those of other protrusions. The lid has a symmetric shape the same as that of the recessed portion of the body, allowing the lid to be mounted in the recessed portion in one of at least two orientations that correspond to at least two different locations of a center of gravity of the golf club head, thereby allowing rapid change in the center of the gravity of the golf club head.

Abstract: A golf club head includes a golf club head body and a cover plate mechanically connected thereto. The golf club head body provides with a striking plate and at least one assembling opening. The cover plate provides with a reinforcing outer edge and a relatively thin shell portion. The reinforcing outer edge is partially arranged on an outer periphery of the relatively thin shell portion of the cover plate. In assembling, the reinforcing outer edge of the cover plate securely connects with an inner periphery of the assembling opening of the golf club head body.

Abstract: A golf club head which mainly includes a shell and a striking plate is provided. In which, the shell has an opening, and a portion of the edge of the opening of the shell has a first engagement portion. Furthermore, the striking plate is located at the opening, and with the shell forms a golf club head. A portion of the edge of the striking plate has a second engagement portion, which is corresponding to the first engagement portion. The shell and the striking plate are mutually engaged respectively using the first engagement portion and the second engagement portion. The golf club head has superior structural strength and manufacturing yield.

Abstract: A golf club head includes a body including at least one compartment, at least one positioning member removably mounted in the at least one compartment, at least one weight member mounted in at least one the positioning member, and at least one retaining member for retaining the at least one weight member in the at least one positioning member. The weight member is concealed in the compartment of the body to provide a good appearance while simplifying polishing procedure and allowing easy replacement of the weight member.

Abstract: A golf club head includes a body and at least one light cover. The body includes a striking face for striking golf balls and a crown. At least one recessed portion is defined in the crown and includes a bonding face. The bonding face includes a plurality of regularly arranged holes spaced by a plurality of resilient ribs. The light cover is securely mounted to the recessed portion. The light cover and the holes reduce a weight of the crown of the golf club head and improve a rearward resilient deforming capacity of the striking face. Further, the resilient ribs assure strength of the recessed portion.
