BACKPACK BLOWER WORK APPARATUS
The purpose of the present invention is to offer less fatigue to an operator by reducing loads to shoulders, the lower back, and legs even in an operation with a large battery. This backpack blower work apparatus comprises a back frame, a volute case mounted in the back frame, a centrifugal fan installed in the volute case, an electric motor that is assembled into the volute case and rotates the centrifugal fan, and a battery that is attached to the back frame and feeds power to the electric motor. The back frame has shoulder belts for shouldering and the volute case in the upper part and has a battery installation space in the lower part. The battery installation space is vertically and horizontally extended longer than in the front-back direction.
