Abstract An end cap for a racket handle includes a tubular member mounted to the racket handle, a collar member connected to the rear end of the tubular member and a board retained in the collar member. A plurality of recesses are respectively defined in the inside and the outside of the tubular member and the inside of the tubular member snugly contacts the racket handle. The collar member has an annular wall extending transversely therefrom and the annular wall snugly contacts the tubular member. The recesses are sealed by the racket handle and the annular wall so as to be defined as chambers which absorb shocks transferred from the racket.
