Claims

[Claims for Utility Model Registration] A stator having a stator core, and an annular plane projecting outward from the cylindrical part at the opening edge of one end of the cylindrical part that accommodates the rotor arranged inside the stator. A case body formed by providing a section, a case end plate attached to the opening at one end of the case body, and a rotor shaft attached to the rotor shaft passing through a bearing support provided at the center of the case end plate. The fan has a plurality of air inlets and a wind introduction part that gradually slopes toward the annular flat part toward the air inlets in a peripheral portion overlapping with the annular flat part, and a plurality of air inlets connected to each of the air inlets. A rectifying air passage is provided on the inner surface, and is located between the fan and an opening at one end of the case body, and is provided to cover the opening at one end, and directs the air discharged from the fan into the case body. In the electric blower, the electric blower is equipped with a synthetic resin rectifying plate that guides air flow, and a fan cover that covers the rectifying plate and the fan and is attached to the opening side of one end of the case body. A plurality of fixing holes are provided in the annular flat part, and the plurality of connecting convex parts are respectively inserted into these fixing holes, and the tips thereof are inserted into the holes of the fixing holes on the back surface of the annular flat part. A rectifier plate fixing structure for an electric blower, characterized in that a peripheral part of the rectifier plate is fixed to the annular plane part by hooking on an edge.
