Claim:
A portable air blowing working machine comprising: an internal combustion engine having an air cleaner disposed in an air-intake system thereof, and an air blower to be rotationally driven by said internal combustion engine; said air cleaner comprising a suction port for inhaling external air, a filter member for cleaning air drawn from the suction port to thereby permit cleaned air to be introduced into an intake port of the internal combustion engine, and a discharge port for enabling part of the air that has been drawn from the suction port to be discharged out of said air cleaner without permitting said part of the air to pass through said filter member; wherein a suction force to be generated by a fan of said air blower is utilized for generating an air flow inside said air cleaner, said air flow being directed to flow from said suction port to said discharge port; and further comprising a back-pack frame for vertically mounting said air blower, wherein an inlet port of the air blower is disposed to face said back-pack frame, said air cleaner is positioned over one of said air blower and said internal combustion engine, and said discharge port of the air cleaner is positioned closer to said back-pack frame to said suction port.
