Abstract

A racket (2) includes a frame (4), a grip (6), a grommet (10), and a string (12). The frame (4) includes a head (14), a first throat (16a), a second throat (16b), and a shaft (18). A maximum value of a thickness of the frame (4) is less than 26.0 mm. The racket (2) has an in-plane stiffness index Gi of greater than or equal to 5000 and less than or equal to 8000. The in-plane stiffness index Gi is a product of a top pressure stiffness value Git expressed in kgf/cm and a side pressure stiffness value Gis expressed in kgf/cm. The racket (2) has an out-of-plane stiffness index Go of greater than or equal to 45000 and less than or equal to 60000. The out-of-plane stiffness index Go is a product of a throat stiffness value Gos expressed in kgf/cm and a ball-hitting face stiffness value Goh expressed in kgf/cm.
