<p>An electric blower comprising an electric motor and an impeller drivingly rotated thereby. A housing and an end bracket connected thereto cooperate with each other to define an internal space within which the electric motor is disposed. A tubular wall surrounding an output shaft of the motor extends from an end wall of the end bracket into a central opening in a shroud plate of the impeller. A bearing is disposed between the tubular wall and the output shaft for rotatably supporting the output shaft. A guide vane assembly introduces air discharged from the impeller, into the internal space. The guide vane assembly is connected to the end bracket at a location radially outwardly remote from the bearing. The guide vane assembly guides the air flow from the impeller, toward openings in a peripheral wall of the end bracket.</p> |
