風機。 A stator and a rotor, a fan that rotates together with the rotor, an air guide that holds the load side bearing of the rotor, an anti-load side bracket that holds the anti-load side bearing of the rotor, and a rectifier that rotates together with the rotor. and a pair of brushes having carbon brushes that are slidably provided within the irregularly shaped tube held by the anti-load side bracket and are pressed by a spring in the direction of the commutator. A shallow V-shaped stopper is provided on the side wall surface of the carbon brush at both ends around the shaft support. An electric blower, characterized in that the electric blower is arranged so that when it comes into contact with the brush holding portion of the anti-load side bracket and rotates, the protrusion prevention is released.
