PROBLEM TO BE SOLVED: To prevent accumulation of dust and dirt to an engine without arranging a dustproof cover on the engine by providing air blowing means capable of blowing air to an engine room separately from an engine cooling air blower. SOLUTION: A support plate 15 is arranged in a part of a hood 14 for forming the ceiling of an engine room, and air blowing means 16 for blowing air toward an engine in the engine room are arranged by two units on the support plate 15. These air blowing means 16 are provided with an air blowing case 18, a motor-driven fan 20 installed in the air blowing case 18 and louvers 22a, 22b, 22c being an airflow direction guide plate swingingly installed in a lower end part of the air blowing case 18 being the downstream of blowing air of the motor-driven fan 20. The motor-driven fan 20 of the air blowing means 16 is actuated by a power source battery of a work machine to blow air even at engine stopping time of the work machine. Air blowing can be turned on and off for a prescribed time regardless of rotation and stopping of the engine by providing a timer.
