<p>An endless metal belt, comprising a ring collected body (31) formed by laminating a plurality of metal rings (R1), (R2), --- slidably each other and a plurality of metal blocks (32), (32), --- slidably supported on the ring collected body (31), wherein a lubrication oil retaining groove (34) is formed in the inner peripheral surfaces of the outside rings (R2), (R3), --- forming the sliding surfaces between the rings adjacent to each other and the inner peripheral surface of the ring (R1) on the innermost periphery of the ring collected body (31) in contact slidably with the saddle surfaces (324), (324), --- of the blocks (32), (32), --- is formed of a flat surface (35) having no lubrication oil retaining groove (34) formed therein, whereby the sliding surfaces between the rings adjacent to each other are lubricated with the lubricating oil retained in the lubricating oil groove (34) so as to reduce the wear of the slidably contact surface, because the inner peripheral surface of the ring (R1) on the innermost periphery of the blocks (32), (32) --- in contact slidably with the saddle surfaces (324) and (324) forms the flat surface (35) with less degree of surface roughness, the wear of the inner peripheral surface is reduced, and the durability of the entire ring colleted body forming the endless metal belt can be increased.</p> |
