PROBLEM TO BE SOLVED: To provide a racket frame which can provide an excellent repulsiveness and controlling property while ensuring a favorable operability by greatly expanding the sweet area without expanding the area of the ball-hitting section. SOLUTION: A window hole 8 which penetrates the internal and external peripheral surfaces of the ball hitting section is provided at least at one region of the ball hitting section. Then, a gut-supporting body 10 is supported and fixed in the window hole 8 in such a manner that the gut-supporting body 10 may activate swinging in the ball-hitting direction by following the warpage of the gut at the time of hitting. |
