LOW NOISE PACKAGE STORING TYPE ENGINE WORKING MACHINE

An engine working machine (1) formed by storing a radiator (5) and a cooling fan (6) for leading heat exchange air for a the radiator (5) in a package (2) together with an engine (3) and a working machine (4), wherein a storing space (E2) for the engine (3) and working machine (4) excluding a ventilating port (13) communicating to a space (15) between the radiator (5) and the cooling fan (6) is shielded by partitions (9) from an air leading space (E1) to which air is led after being passed through the radiator (5) by the cooling fan (6), and a cooling air leading port (12) for externally cooling the engine (3) and the working machine (4) is formed in a part of the package (2) so that outside air led from the cooling air leading port (12) passes the storing space is exhausted from a ventilating port (13) to the air leading space (E1) to which air is led after having passed through the radiator (5).
