Claims

1. Step chain and, An oil pan located below the step chain, An escalator device comprising a sprayer for spraying an oil gelling agent onto the oil that drips from the step chain into the oil pan.

2. The oil pan includes a lower flat portion, an upper flat portion, and an inclined portion connected to the lower flat portion and the upper flat portion. The escalator device according to claim 1, wherein the oil, which has been sprayed with the oil gelling agent and gelled, slides down the inclined portion of the oil pan toward the lower flat portion by its own weight.

3. The inclined portion includes a downward inclined portion connected to the lower flat portion, an upward inclined portion connected to the upper flat portion, and an intermediate inclined portion connected to the downward inclined portion and the upward inclined portion. The escalator device according to claim 2, wherein the first spray nozzle of the sprayer is located above or to the side of at least one of the upper flat portion or the upper inclined portion.

4. The escalator device according to claim 3, wherein the second spray nozzle of the sprayer is located above or to the side of at least one of the intermediate inclined portion or the downward inclined portion.
