Abstract: A golf club includes a shaft, a grip member positioned around a tail portion of the shaft, an expanding component positioned in the tail portion of the shaft, and a fastening component; the grip member has a holding room to receive the tail portion of shaft; the expanding component is made of rubber, and has an axial central hole, and a rugged. outer side; the fastening component has a head part, which has a greater diameter than the central hole of the expanding component; the fastening component has threads thereon; the fastening component is inserted in the axial hole of the expanding component, with the head part being pressed against the grip member so that the rugged outer side of the expanding component is tightly pressed against the inner side of the tail portion of the shaft, and the grip member and the shaft are fastened together.

Abstract: A golf club includes a shaft, and a grip member secured around a tail portion of the shaft; a constricting and fastening component is secured in the grip member to fasten the shaft to the grip member; the constricting and fastening component includes a constricting ring around the shaft, and a driving rod, which can be operated so as to reduce the circumference of the constricting ring in order for the constricting ring to be tight around the shaft, thus preventing the shaft from turning relative to the grip member; the driving rod can be operated so as to expand the constricting ring in order for the ring to loosen the shaft, thus allowing the shaft to be separated from the grip member.

Abstract: A sleeve includes an inner sleeve part securely fitted on a handle end portion of a golf club, and two outer sleeve parts; the inner sleeve part has circular concavities spaced apart on an outer side thereof; the outer sleeve parts are positioned around the inner sleeve part, and each stuck to the inner sleeve part at two ends thereof in a sealing manner such that an air containing sealed room is formed between it and the inner sleeve part, making the sleeve capable of functioning like an air cushion with increased capability to absorb reaction force from hitting a golf ball.

Abstract: A golf club has a handle sleeve around the shaft, which sleeve includes an elastic rubber sleeve part, and an outer covering part; the rubber sleeve part has such an inner diameter as to be tightly secured around the shaft; the rubber sleeve part has a recess portion on an outer side; the covering part includes an inner layer made of the same material as the rubber part, and an outer grip layer; the outer grip layer and the inner layer are sewn together; the outer covering part and the rubber sleeve part are securely stuck together by means of adhesive, which is applied over the inner layer of the outer covering part and the rubber sleeve part, and which has already dissolved the inner layer of the outer covering part and the rubber sleeve part slightly before the outer covering part is positioned onto the rubber sleeve part.

Abstract: An injection-molding tool for a golf club grip includes a base member and a detachable molding member attached thereto. The base member is provided with a screw rod extended therefrom for screw connection. The detachable molding member includes a screw hole for receiving the screw rod of the base member, and a plurality of molding plugs extended therefrom and disposed around the screw hole. Each of the molding plugs has a cross-sectional configuration to thereby form a desired type of a structural elastic buffer of the golf club grip.

Abstract: A grip sheath used for a golf club includes a tapered, elongated hollow body made of an elastomer. The tapered, elongated hollow body has an open end and a closed end opposite to and larger than the open end. The hollow body is formed with a longitudinal central hole extending from the open end towards the closed end and with a plurality of longitudinal blind bores extending from the closed end towards the open end. In addition, the longitudinal blind bores are arranged around the longitudinal central hole. Therefore shock may be significantly absorbed at the grip sheath when a ball is hit by the golf club.
