Abstract:
To improve space efficiency of a tank integrated type pump device.
A suction plug 32 connected to a suction plug connection hole 11 on the side of a pump device 2 is provided between a lowermost part 30 of a tank body 24 of a reservoir tank 3 and an oil level V. A pressure chamber 34a is provided in a tank body 24 perpendicularly below an opening part 32a of the suction plug 32 on the side of the tank body 24.
