管２を接続する。The oil supply device of the present invention also uses a centrifugal pump as the oil supply pump connected to the oil supply motor 3, and connects the impeller 10 of the centrifugal pump to the rotating shaft 11 of the oil supply motor 3. Then, a short pipe 12a provided with a check valve 12 is connected to the suction pipe 4a side of the centrifugal pump via a guide 14, and the oil supply pipe 2 is connected to the short pipe 12a.

る。In the lubricating apparatus having such a configuration, the vortex preventing plate 13 is provided in the suction pipe 4a of the centrifugal pump. The eddy current preventive plate 13 is formed as a vertical plate integrally projecting from the inner wall of the suction pipe 4a toward the center as an example, and the lower end of the eddy current preventive plate 13 does not allow the check ring 12 to come off the guide 14. It also acts as a stopper. Therefore, it is not necessary to separately provide a stopper separately, and the backflow prevention plate 13 is also provided with the suction pipe 4.
Since the backflow prevention plate 13 can be integrally formed on the inner wall of a, the process of separately manufacturing the backflow prevention plate 13 and incorporating it into the suction pipe 4a can be reduced.

至る。Next, the operation will be described. When the refueling motor 3 is driven at the time of refueling, the rotation is transmitted to the impeller 10 of the centrifugal pump which is the refueling pump 4 via the rotary shaft 11, and this rotates. Therefore, the oil sucked into the oil supply pipe 2 from the underground oil storage tank pushes up the check valve 12, passes through the suction pipe 4 a, and further reaches from the oil supply pipe 2 to the oil supply hose 8 and the oil supply nozzle 7.
