PROBLEM TO BE SOLVED: To provide a low friction chain reduced in sliding resistance, namely, sliding contact friction with a guide member. SOLUTION: The low friction chain 100 is comprised of a roller chain wherein pluralities of inner plates 110 and outer plates 140 formed with pairs of pin holes 141 and deviated in a chain longitudinal direction, are connected to freely bend by connection pins 130 respectively inserted in the pairs of pin holes 141. In the inner plate 110 and the outer plate 140, at least end faces 112, 142 sliding on the guide member G are convexly curved. COPYRIGHT: (C)2008,JPO&INPIT
