PROBLEM TO BE SOLVED: To reduce noise while maintaining a smooth flow of cooling wind with a comparatively simple structure, and to prevent entry of rainwater entrained from an intake port into an engine room.SOLUTION: An engine 1 driving a power generator 2 as a working machine, a radiator 4 of the engine 1, and a cooling fan 5 are housed in an engine room 12. An intake port 13 is provided at a front surface lower part of a front duct 11 in which lower and upper spaces are isolated by a partition wall 15. Air sucked from the intake port 13 is introduced into the engine room 12 from a rear-side floor surface through a base duct 9. The air in the engine room 12 is sent to the upper space of the front duct 11 through a radiator 4 by the cooling fan 5, and is discharged to the outside from a wind discharge port 16 provided at the rear side from the front duct 11 through a roof duct 10. |
