    Abstract: A grip for a golf club includes an insertion hole having a circular cross section for inserting a club shaft thereinto. The inner periphery of the insertion hole is provided with a longitudinal rail which height and width ranges between 0.3 mm and 2.0 mm and is pressed toward outside after inserting the club shaft into the insertion hole such that a rib is formed at the outer periphery of the grip in correspondence to the longitudinal rail. Gaps are produced between the outer periphery of the club shaft and the inner periphery of the insertion hole of the grip at both sides of the longitudinal rail, thereby comforting player's hands while holding the grip and facilitating club shaft alignment and preventing the grip from slipping away from the player's hands while hitting balls.
