PROBLEM TO BE SOLVED: To provide a suspended chain which has a simple structure, facilitates oil supply, and can avoid oil film rupture and adhesion (heating conglutination) at a position causing a relatively large friction when a chain bends.SOLUTION: In a suspended chain 100, a coupling pin 130 is penetrated through an insertion hole 121 of an inner link plate 120 to be pressed into a pin hole 111 of the outer link plate 110. A roller 140 arranged between a pair of inner link plates 120, 120 is rotatably engaged with a periphery of the coupling pin 130. A groove part 143 connecting a roller outer periphery 141 and a roller inner periphery 142 is formed on at least one of the right and left side surfaced. |
