Abstract
A grommet of a racket includes a tubular portion. The tubular portion has a through hole through which a string is passed. The through hole has a base-side opening, a side wall, and a tip-side opening. In the tip-side opening, an inner dimension in a direction parallel to a face is larger than an inner dimension in a direction perpendicular to the face. In the tubular portion, the string is in contact with the side wall from the base-side opening to the tip-side opening.
