PROBLEM TO BE SOLVED: To provide an oil supply device for a gearing chain of a passenger conveyor capable of easily acquiring a required lubrication following the fluctuation of a stretched wire of the gearing chain in a transmission operation. SOLUTION: An oil supply body 23 is fittingly located at a part where the gearing chain 10 is stretched, and the oil supply body 23 is shiftably held against a main frame 1 by a holding mechanism 27. An oil supply tub 20 provided in the main frame 1 and the oil supply body 23 are connected with a flexible tube 26. Thereby, the oil supply body 23 moves following the fluctuation of a stretched wire of the gearing chain 10, and positional deviation is not generated between the flexible tubes 26 opened in the upper part of the oil supply body 23 and the gearing chain 10. Accordingly, the lubricating oil of the oil supply tub 20 is dripped to lubricate the gearing chain 10. Therefore, the gearing chain 10 can surely be lubricated to prevent poor lubrication, and the increase of the frequency of maintenance work because of the poor lubrication of the gearing chain 10 is prevented so that a maintenance cost does not increase.
