The utility model provides a suspended chain, which has a simple structure, facilitates oil supply, and can avoid rupture and adhesion (heating conglutination) of an oil film at the position with relatively large friction when a chain is bent. The suspended chain (100) is characterized in that coupling pins (130) penetrate through insertion holes (121) of inner chain plates (120), and are embedded into pin holes (111) of outer link plate (110) in a press-in manner; and rollers (140) are arranged between a pair of inner chain plates (120 and 120), and embedded into the periphery of the coupling pins (130) in a free rotation manner, and groove portions (143) for connecting roller outer peripheries (141) and roller inner peripheries (142) are formed on at least one side surface of the left side surface and the right side surface of the rollers.
