Then, a hollow section is formed at the central section in the crossing direction which crosses the hitting surface of the racket of the shaft. A folding-back section is formed only on the external edge of the frame, wherein the folding-back section folds back the string that has come out to the outside of the frame from the insertion hole along the internal side of the frame in order to place the string on the internal side of the frame from the insertion hole.
