PROBLEM TO BE SOLVED: To provide a racket frame having both desired rebounding performance and desired holding feel.SOLUTION: A racket frame 2 includes a head 4, a shaft 8, and a pair of throats 6 extending from the head 4 to the shaft 8. A flexural rigidity Gof the throats 6 in a low load range (from 5 kgf to 15 kgf) is equal to or greater than 600 kgf/mm and equal to or less than 900 kgf/mm. A flexural rigidity Gof the throats 6 in a high load range (from 45 kgf to 55 kgf) is equal to or greater than 900 kgf/mm and equal to or less than 1200 kgf/mm. A rigidity ratio (G/G) of the flexural rigidity Gand the flexural rigidity Gis equal to or greater than 0.70 and equal to or less than 0.85. |
