Abstract: A side-blown fan is formed by a case and a blade member. The case includes a side-outlet, an axial inlet and a protrusion. The protrusion extends from an edge of the axial inlet toward the center of the axial inlet. The blade member is embedded in the inside of the case. In the radial direction, a high air pressure region exists between the blade member and the case. The protrusion covers the high air pressure region and a part of the blade member.
