Racket frame

Abstract

A racket frame 10 of the present invention includes fiber reinforced resinous layers. At least one of the fiber reinforced resinous layers is a layer (L1) in which a rubber component is blended. A matrix of the layer (L1) contains a rubber component. When a total weight of a matrix contained in the racket frame 10 is defined as Wm (g) and a total weight of the rubber component contained in the frame 10 is defined as Wg (g), a rate Rg (%) of the total weight Wg to the total weight Wm is 2.5(%) or greater and 17.5(%) or less. In this frame 10, a ratio [Rh/Rs] of plane rigidity Rh to throat rigidity Rs is 0.05 or greater and 0.2 or less. Preferably, the plane rigidity Rh is 30 (kgf/cm) or greater and 70 (kgf/cm) or less. Preferably, the throat rigidity Rs is 250 (kgf/cm) or greater and 800 (kgf/cm) or less.
