VACUUM CLEANER

PROBLEM TO BE SOLVED: To provide a vacuum cleaner in a manner that the vacuum cleaner causing a small air trunk loss in an air trunk before a motor for electric blower driving can be obtained. SOLUTION: In a vacuum cleaner which is above a motor for electric blower driving and is equipped with a combination air trunk where airflow is introduced from a dust chamber, a communication hole which communicates with the combination air trunk is formed in the posterior wall of the dust chamber. This communication hole and the inlet of air introduced by the motor are connected by the hollow tubular combination air trunk. Air discharged from the communication hole is inflected less than a given angle at the connection of the combination air trunk and is vacuumed and introduced to the suction opening side of the motor.
