PURPOSE: To obtain a good racket frame having safety and durability, by forming a grip-cap-formed projected section integrally with a shaft section for composing a racket frame.

CONSTITUTION: A racket frame 1 has a mechanism for forming a grip-cap- formed projected section 5 integrated continuously with a shaft section 3, at the corresponding section of the fitted grip cap of the shaft section 3 at least. On the shaft section 3 inserted in a grip section 4, a rotation-proof section 7 for the racket frame 1 not to be rotated in the grip may be formed. The shaft section 3 and the grip-cap-formed projected section 5 are integrally formed, and so a stress generated in case of striking a shuttlecock is relaxed to be dispersed by the continuously and integrally formed grip-cap-formed projected section 5, and the stress is prevented from being concentrated, and strength is remarkably improved.
