ABSTRACT:
Blowing apparatus suspensible from one's shoulder is provided with an axial blower having the rotor thereof coupled with the crankshaft of a gasoline engine. The stator blades of the blower are removably fixed peripherally to the housing of blower and partially to the casing of the engine. The engine does not require a cooling fan because it is sufficiently cooled by the suction-air flowing around. Further an independent fuel tank is not required because of a hollow guide disposed in front of the rotor and serving as a fuel storage. The nozzle, flexible tube, and the discharge housing of the blower can be made of synthetic plastics in the form of a single annular body without any connecting means. Consequently, the apparatus of the present invention is remarkably light and compact.
