ABSTRACT:
Disclosed is an upright-type electric vacuum cleaner which comprises a suction port body provided with a rotary brush and a main body case supported tiltably on the suction port body. Improvements are made in details such as the arrangement for supporting the main body case in the suction port body, the arrangements of mounting a handle onto the main body case, the configuration of a main body duct, the arrangement of a rotary brush, the arrangement of a cover of the main body case, and the arrangement of a T-shaped joint for connecting the main body duct and a dust filter means, thereby increasing the strength and rigidity of each of these parts and improving the performance of the vacuum cleaner.
