Abstract: A composite racket frame includes a shaft constituted by a shell and a foamed core and having a portion of smallest cross-section substantially at an intermediate portion thereof relative to any other portion, the dimension of the cross-section of the portion being restricted only in a direction substantially perpendicular to the plane of the string web. The shaft further having two stepped width-increasing portions respectively extending from the smallest portion toward the throat section and the end of the shaft. The grip member of the shaft extends at least partly over the smallest cross-section portion, and the stepped width-increasing portions are stepped both on the outside and on the inside of the shell of the shaft.

Abstract: A fixing device for a fishing rod is used for joining a inner tube and an outer tube. The inner tube is slidably received within the outer tube and can be fixed onto the outer tube firmly. The fixing device includes a fixing piece or coupling operatively mounted on the outer tube and a packing ring made of flexible material which is urged to grasp the inner tube by the fixing piece.

Abstract: A mould used for making a racket frame comprises an upper mould piece, a lower mould piece and an intermediate mould piece which cooperate to form a cavity that imparts a racket frame shape with the parting line of the mould pieces lying apart from a plane X-X that passes through stringing holes which will be drilled in the frame formed in the mould, thereby avoiding the performing of the deflashing operation at the portion near the stringing holes and preventing the damage of the fiber reinforcement for the string at that portion.
