Abstract: PROBLEM TO BE SOLVED: To improve the hitting performance of a racket by forming long and slim gut holes parallel and stringing the racket so that the gut crossing the frame can slide along the edge of the frame when a ball is hit on the racket. SOLUTION: An upper hole 1 is formed outside the frame 5 for stringing a racket, and it is a gut hole cut through the outer member of the frame 5 to which the top of each gut string 2 is first inserted.
