PROBLEM TO BE SOLVED: To provide a lubricating oil replenishing device capable of improving replenishing work of lubricating oil. SOLUTION: Oil supply tanks 30 respectively arranged in correspondence with escalators 21 are each provided with an oil level sensor 36, a flow-in port 32, and a flow-out port 34 at a full oil level height for floors except for the lowermost floor. The flow-in port 32 is connected to the flow-out port 34 of the oil supply tank 30 on a floor immediately above through an oil supply pipe 38. A collective oil supply tank 40 is connected to the flow-in port 32 of the oil supply tank 30 on the uppermost floor. When any of the oil level sensors 36 transmits a replenishing command signal, a replenishing control part 46 makes the lubricating oil flow out of the collective oil supply tank 40. The flown lubricating oil flows from the uppermost floor to the lower floors in order. Thus, the oil supply tanks 30 on the respective floors are automatically replenished.
