A plurality of enlarged stationary flow channels (difusers) provided opposite to the outer periphery of the impeller, a communicating path that guides the enlarged stationary flow channels to the outer periphery and goes around from the outer periphery to the back side; What is claimed is: 1. A blower having a return flow path that leads inward on the back side and guides air to an electric motor intake port, and a blade forming the enlarged stationary flow path is formed in a triangular arc shape. 2 In claim 1, the distribution of arcs is (
r 4 - r 3 ) is l, the first circular arc is the section of the radial position r 3 + (0.4 to 0.6) l, and the second circular arc is the section of the radial position r 3 + (0.4 to 0.6 )l～ r3 +(
0.65 to 0.85)l, the third circular arc is formed in the radial position r3 + (0.65 to 0.85)l to r4 , and the angle distribution is the angle at the radial position rn . A blower characterized in that, where βN is the time of one circular arc and βM is the end point of the first circular arc when three circular arcs are formed, βM>βN.
