Abstract: Disclosed is a backpack-type air-blowing working machine in which a volute casing incorporating a centrifugal fan configured to be driven by an electric motor is assembled in an upstanding manner to a backpack frame to be carried on the back of an operator using shoulder straps during use. The backpack-type air-blowing working machine includes a rechargeable battery pack connected to the electric motor and detachably attached to the backpack frame, such that a position of the center of gravity of the backpack-type air-blowing working machine as viewed from the rear thereof is located below a rotation axis of the centrifugal fan, and a position of the center of gravity of the backpack-type air-blowing working machine as viewed from the side thereof is located forward of a rear end of the volute casing.
