The above-mentioned purpose is to make the oil supply device installed in the machine room an oil supply device that discharges oil only when necessary, and to provide a nozzle with a check valve that opens only when a predetermined pressure acts on the tip of the pipe from this oil supply device. On the one hand, a bracket that is screwed to the running surface of the guide rail and supports the nozzle is provided, and on the other hand, the oil supplied through the nozzle is applied to the surface of the guide rail on the upper part of the car or counterweight. This is achieved by providing a coating device.

[Action]

The oil discharged by the mechanical oiling device is supplied to the container of each car coater or counterweight coating device through a pipe and a nozzle with a check valve at the tip of the pipe, and the appropriate amount of oil is supplied to the container. Is gradually applied to the surface of the guide rail. Therefore, the oil will not be scattered due to excessive refueling, the guide rail will not be rusted due to insufficient refueling, and the riding comfort of the car will not be adversely affected. Further, since the nozzle with check valve is supported by the bracket which is screwed to the traveling surface of the guide rail, the nozzle can be mounted easily and surely.
