The first electric motor assembly is mounted to the pump case so that the corresponding electric motor has a rotational axis line in parallel with the first pump shaft in a state where the electric motor is positioned on an opposite side to the second control shaft with respect to the first control shaft and is also positioned on an opposite side to a first end of a first pump shaft with respect to a virtual plane that passes through the axis lines of the first and second control shafts. The second electric motor assembly is mounted to the pump case at a posture obtained by rotating the first electric motor assembly by 180 degrees about a virtual center line that is disposed in parallel with the first and second control shafts and is located at a center between the first and second control shafts, thereby the electric motor is positioned on an opposite side to a cooling fan, which is driven by the second end of the second pump shaft, with respect to the virtual plane.
