A movable clamping means is provided, and the clamping means engages with the engaging portion when the lid is closed and is housed along the outer surface of the lid, and engages with the engaging portion when the lid is opened. A clamp knob is provided which releases the engagement and projects outwardly from the outer surface of the lid body to serve as a handle of the lid body, and the operating direction of the clamp knob of this clamp means is determined according to the direction in which the suction port main body is cleaned. The longitudinal direction of this suction port body is orthogonal to the main movement direction.

(Function) The suction port body of the vacuum cleaner of the present invention is such that when removing lint, hair, etc. attached to the rotating brush, the clamp means of the lid body engages with the suction port body by operating the clamp knob of the clamp means. When the lid body is disengaged from the mating portion, the lid body is in a disengaged state, and when the lid body is in the disengaged state, the clamp knob protrudes outward from the outer surface of the lid body, and the clamp knob is gripped. This allows the lid to be easily removed, and by removing the lid, an opening corresponding to the rotating brush on the upper surface of the suction port body is opened. Furthermore, when the lid is closed, the opening corresponding to the rotating brush is closed by the lid, and by engaging the clamp means with the engaging portion, the clamp knob of the clamp means is pressed against the outer surface of the lid. Since the clamp knob does not protrude outward from the outer surface of the lid, it does not get in the way during cleaning and there is no risk of damage. Furthermore, since the operating direction of this clamp knob is perpendicular to the main movement direction of the suction port body during cleaning, this clamp knob will not get caught on something during cleaning, and the lid body will not accidentally come off. do not have.
