PURPOSE: To damp the vibration transferred to a frame via the function of the frame itself by fixing a vibration suppressor unit on at least part of a member constituting a racket.
CONSTITUTION: A vibration suppressor unit 5 constituted of a vibration suppressing material 7 and restricting material made of a raw material with the strength end rigidity higher than those of the vibration suppressing material 7 is fixed on at least part of a member constituting a racket. The vibration suppressor unit 5 constituted of a shock absorbing material 9, the vibration suppressing material 7 and the layered shock absorbing material incorporated in it is stored near the ends of guts 1 at the top section of a frame 2 via a restricting plate 8 with a fixed thickness, its outer edge section is closed by a frame mold to form a casing structure, for example, and the restricting plate 8 is fixed to the upper end section of the frame 2 via a separate shock absorbing material 9 with stoppers 11. The shock vibration transferred from the guts 1 to the frame 2, a shaft and a grip when a ball is driven can be effectively damped.
