摘要

To provide a concept improved to construct a pump device.SOLUTION: A pump device 100 for a vehicle includes a pump 101, a drive portion 103 existing in a drive portion housing 108, and connected with the pump 101 through a drive shaft 102, a suction opening portion 104 at a first side of the pump 101 on the side opposite to the drive portion 103, and a pressure port 110 at a second side of the pump 101 facing the drive portion 103. The pressure port 110 is guided through the drive portion housing 108, and opened to an annular pressure channel 106 outside of the drive portion housing 108.SELECTED DRAWING: Figure 1
