A racket including a string-stretching part for forming a ball-hitting face by tensionally mounting strings in string holes, formed through the string-stretching part, in which grommets are mounted respectively. As the grommets, a double-tubular grommet is mounted in at least one of the string holes. The double-tubular grommet is formed as an integrally molded article, including an inner tubular portion having a string insertion hole through which the string is inserted with the string in contact with the string insertion hole and pulled from an inward-end open portion thereof or an outward-end open portion thereof; an outer tubular portion fitted in the string hole formed through the string-stretching part with the outer tubular portion spaced at a certain interval from the inner tubular portion; and a base portion integrally connected with an outward-side end of the inner tubular portion and that of the outer tubular portion and disposed on a peripheral surface of the string-stretching part.
