Zusammenfassung:	The purpose of the present invention is to provide a chain oil supply system capable of supplying oil not only to a step chain among chains of a passenger conveyor but also to the entire circumference of the passenger conveyor without exception. The chain oil supply system includes: a pump unit (14) pumping lubricating oil; a first pipe (15) connected to a pump unit (14) and having a discharge hole facing the step chain (6) among the chains of the passenger conveyor; a second pipe (17) branched from the first pipe (15) and having a discharge hole facing the chain among the chains of the passenger conveyor, not the step chain (6); and an electric valve (18) formed in the second pipe (17) and closed after an elapse of a preset time period from the opening thereof. The discharge hole of the second pipe (17) is formed to enable the lubricating oil to flow continuously.
