ABSTRACT:
Disclosed is a locking unit to fix a removable cyclone dust collector in a receiving portion of a main body of a vacuum cleaner. The locking unit comprises a locking recess formed at one side of a contact surface of the cyclone dust collector and the receiving portion. A lock element ascends and descends between a locking position and an unlocking position with respect to the locking recess and passes through a hole which is formed at another side of the contact surface of the cyclone dust collector and the receiving portion. An operating member selectively moves the lock element to the locking position and the unlocking position.
