Abstract
(EN)
A hydraulic excavator 1 is provided with a motor generator 48 that can be used as a power source, an engine room 47 that accommodates the motor generator 48, a suction pipe 483a and duct hose 55 through which air outside the engine room 47 is introduced into a housing 483 of the motor generator 48 by a suction force generated by blades 481d that rotate integrally with a rotor shaft 481c of the motor generator 48 inside the housing 483, and an exhaust pipe 483b through which air inside the housing 483 is introduced into the engine room 47 by the rotation of the blades 481d.
