Abstract
A blower may include a plurality of batteries; a centrifugal fan configured to change a flow direction of air from a first direction extending along the rotation axis to a radially outward direction of the rotation axis; a volute casing including a discharge port and configured to guide the air from the centrifugal fan along a circumferential direction of the rotation axis to the discharge port; and a main grip disposed radially outward of the rotation axis and outside of the volute casing and configured to be gripped by an operator. A central axis of the main grip may extend along a reference plane perpendicular to the rotation axis. A distance from the reference plane to a center of gravity of the blower may be less than or equal to 1.5 times a width of the main grip.
