<P>PROBLEM TO BE SOLVED: To provide a lubricating oil oozing-out type chain for reducing sliding abrasion between the inner peripheral surface of a bush and the outer peripheral surface of a connecting pin over a long period, by exhibiting an excellent lubricating oil gradual releasing performance while avoiding reduction in chain strength, an increase in a chain manufacturing burden and an increase in bending resistance, and preventing the leaking-out of lubricating oil when operating a chain and the intrusion of external dust-dirt. Ž<P>SOLUTION: This lubricating oil oozing-out type chain 100 includes an inner plate 110, a bush 130, an outer plate 150 and the connecting pin 160. An oil retaining material 180 is arranged in an exposed state in an oil retaining material reservoir 161 arranged in the center in the longitudinal direction of the connecting pin 160.
