A multi-piece rim which does not need much labor for supporting, and does not increase the number of components to be managed and the number of needed tasks. A lock ring (40) to be fitted in the groove (11a) of a gutter band (11) is divided into a plurality of portions (41, 42), and they are coupled at one end (41a, 42a) of each through a flexible coupling member (43). Alternatively, a lock ring (140) is formed into a substantially C-shape obtained by cutting a part of a circular ring, and is constituted of a first portion (141) where the length of a chord at the cut portion is substantially equal to the diametral dimension of a hub, and a second portion (142) having a shape corresponding to that at the cut portion of a circular ring in the first portion.

L'invention concerne une jante en plusieurs éléments qui ne nécessite pas de beaucoup de travail pour le support et n'augmente pas le nombre de composants devant être gérés et le nombre de tâches nécessaires. Une bague de verrouillage (40) devant être montée dans la rainure (11a) d'une bande de crochet de jante (11) est divisée en plusieurs parties (41, 42), et elles sont couplées à chaque extrémité (41a, 42a) par un élément d'accouplement souple (43). En variante, une bague de verrouillage (140) est formée sensiblement en forme de C obtenue par découpe d'une partie d'une bague circulaire, et elle est constituée d'une première partie (141), dans laquelle la longueur d'une corde au niveau de la partie découpée est sensiblement égale à la dimension de diamètre d'un moyeu, et une seconde partie (142) ayant une forme correspondant à celle au niveau de la partie découpée d'une bague circulaire dans la première partie.
