PROBLEM TO BE SOLVED: To improve blast characteristics of a blower by reducing resistance in a blast passage by a mounting leg. SOLUTION: A motor 2 and an impeller 3 connected to a rotary shaft of the motor 2 are stored in a cylindrical casing 1. The motor 2 is fixed on the casing 1 via a plurality of mounting legs 14 provided with keeping an interval in a circumference direction. A hole 14a constructing an opening part is provided on each mounting leg 14 and swirl generated in rear of the impeller 3 passes through the hole 14a in such a manner that the same crosses the mounting leg 14 to reduce reflection after collision on a flat surface part of the mounting leg 14.
