A scavenging blower includes a fan driven by an air-cooled, two-cycle engine for blowing air through an air discharging port. The fan is housed in a fan chamber disposed in side-by-side relation to the engine, and an air passageway is formed around a crankcase of the engine and a fuel tank is located beneath the engine. A handle gripped by one hand is attached to the outer periphery of the fan chamber so that the blower can be operated single-handed.
