MULTI-PIECE RIM AND ITS ATTACHING/REMOVING METHOD

摘要

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.
