PROBLEM TO BE SOLVED: To enlarge a sweet spot of a racket without changing the shape of a frame.SOLUTION: A racket comprises: a grip; an annular frame having a plurality of through-holes penetrating from an inner circumference to an outer circumference; a shaft for connecting the grip and the frame to each other; and a grommet which is attached to the outer circumference of the frame, includes a plurality of cylinder parts inserted into the plurality of through-holes formed in the frame, respectively, and a base part having a plurality of communication holes connecting the cylinder parts to one another and having communication holes communicating with the insides of the respective cylinder parts, and enables strings to be inserted into the cylinder parts and the communication holes. In the racket, when either the longitudinal direction of a racket or a direction orthogonal to the longitudinal direction on the hitting face of the racket is made a first direction, the portion of a base part to be attached to a second position on the outer side in the first direction than the first position has thickness from the inner circumference to the outer circumference larger than the portion of the base part to be attached to the first position in the first direction in the outer circumference of the frame. |
