PROBLEM TO BE SOLVED: To provide a guide rail oil recovery device of an elevator, capable of suppressing mixing of rainwater and further separating and discharging moisture from the oil mixed with the rainwater.SOLUTION: A recovery tank includes a plurality of separation tanks 111 and 112 connected with one another to be arranged in a flowing direction. Each separation tank includes an inflow tank 111b (112b) disposed on the upstream side of the flowing direction in which oil O contained in liquid separates to flow by its specific gravity difference, an outflow tank 111c (112c) adjacently disposed on the downstream side of the inflow tank 111b, and a partition plate 111a (112a) formed as a partition wall of the inflow tank and the outflow tank. Below the partition wall, a communication path 111e (112e) is formed to communicate the inflow tank and the outflow tank with each other so that the liquid in the inflow tank flows to the outflow tank. At the upper end of the outflow tank, a residual liquid discharge part for spilling the liquid overflowing from the outflow tank to the outside of the separation tank. |
