To reduce cost for a heating element cooling device having a plurality of independent cooling circuits for cooling a heating element, and to improve the mounting property of the heating element cooling device.
One motor portion driven by electricity, and first and second pump chambers 12c, 12d including blades 12i, 12j driven to rotate by the motor portion, are disposed in a pump housing of a pump 12. The first pump chamber 12c is connected to a electric equipment cooling circuit 11 through which cooling fluid absorbing heat from a traveling motor 13, a generator 14, and an inverter 17 and radiating the heat of the traveling motor 13, the generator 14, and the inverter 17 by an electrical equipment radiator 15 passes The second pump chamber 12d is disposed in an engine cooling circuit 21 through which cooling fluid absorbing heat from an engine 24 and radiating the heat of the engine 24 by an engine radiator 27 passes.
