Abstract

L'objectif de la présente invention consiste à augmenter le degré de liberté d'ajustement de poids ou d'un point d'équilibre. L'invention concerne une raquette (10) comprenant : un cadre (13) s'étendant dans une forme annulaire ; une partie de préhension (11) ; et une tige (12) destiné à raccorder le cadre et la partie de préhension. Un corps de tige (22), qui est une section de la tige autre qu'une section raccordée au cadre, possède des régions creuses (23, 24) dans des parties de celui-ci dans la direction d'extension et possède une région pleine (25) dans la partie restante. Par une modification de la longueur ou de la position des régions creuses et de la région pleine dans la direction d'extension du corps de tige, le poids total et le point d'équilibre de la raquette peuvent être ajustés.
