ABSTRACT:
In a pump plate (26) of a feed pump, an inlet port (26b) and an outlet port (26c) are formed around a shaft hole (26a) through which a driving shaft is inserted, and a rib (26f), which partitions each of the inlet port (26b) and the outlet port (26c) in the circumferential direction thereof and connects opposite sides (an inner peripheral side and an outer peripheral side) of each of the inlet port (26b) and the outlet port (26c), is provided. Namely, each of the inlet port (26b) and the outlet port (26c) is divided into two portions in the circumferential direction thereof, by the rib (26f).Therefore, when the feed pump is fastened to a side face of a pump housing by bolts, even if the thickness of the pump plate (26) is not increased, the deformation of the center of the pump plate (26) can be prevented.
