Abstract
A tennis racket includes a frame and a grommet. The frame includes a grommet groove, a small groove, and a hole. The small groove is recessed from the grommet groove. The grommet includes a base and a pipe. In a state where the grommet is attached to the frame, the base is accommodated in the grommet groove, and the pipe extends through the hole. The base is not positioned inside the small groove. Therefore, at the back of a back side surface of the base, there is a space derived from the small groove.
