PROBLEM TO BE SOLVED: To solve a problem wherein height of a rear face of a link plate being a guide is small and a chain is twisted and meshed with a sprocket, although both sides of the sprocket for driving an inner face are guided in the link plate of a link for driving an outer face. SOLUTION: An inner side link plate 14 in a row 12 of links for driving the outer face is constituted to have a high (H) rear surface side, and a link plate 16 in a row 15 of links for driving an inner face is guided by the inner side link plate 14 and is meshed with the sprocket 21. The link plates 13, 16 have the same side face shape, and a link plate 16<SB>1</SB>is thin when compared with the other link plates 13, 14, 16. COPYRIGHT: (C)2006,JPO&NCIPI
