163 and 164 having a diameter that is at least the same as the length of the diameter of the inner circumferential surface of the connection hole 133 . Unlike an embodiment of the present invention, the second coupling region 162 itself may be provided to have a diameter that is at least the same as the length of the diameter of the inner peripheral surface of the connection hole 133 .

However, according to an embodiment of the present invention, the diameter of the second coupling region 162 itself is provided to have a smaller diameter than the diameter of the inner circumferential surface of the connection hole 133 , and the sealing of the second coupling region 162 is provided. The

protrusions

163 and 164 may be provided to have a diameter that is at least the same as the length of the diameter of the inner circumferential surface of the connection hole 133 .

The sealing

protrusions

163 and 164 may be provided to protrude radially from the outer peripheral surface of the second coupling region 162 .

The sealing

protrusions

163 and 164 are provided to contact the inner circumferential surface of the connection hole 133 when the second coupling region 162 and the connection hole 133 are coupled to each other to maintain the sealing between the sealing member 160 and the connection hole 133 . may be arranged to do so.

As described above, the length of the diameter of the second coupling region 162 itself is provided to be smaller than the length of the diameter of the inner circumferential surface of the connection hole 133 so that the second coupling region 162 is easily inserted into the connection hole 133 . can be provided. The sealing

protrusions

163 and 164 may be in contact with the inner circumferential surface of the connection hole 133 in the middle in which the second coupling region 162 is inserted, thereby sealing the sealing member 160 and the connection hole 133 .

The sealing

protrusions

163 and 164 may include the first sealing protrusion 163 and the second sealing protrusion 164 having a diameter longer than the diameter of the first sealing protrusion 163 .

The second sealing protrusion 164 may be provided to have a diameter longer than the diameter of the inner circumferential surface of the connection hole 133 .

The first sealing protrusion 163 may be provided to have a diameter approximately the same as the diameter of the inner circumferential surface of the connection hole 133 .

Accordingly, when the second coupling region 162 is inserted into the connection hole 133 , the second sealing protrusion 163 may be provided to be press-fitted in the radial direction of the connection hole 133 . Through this, a gap may not occur between the second coupling region 162 and the connection hole 133 .

The first sealing protrusion 163 and the second sealing protrusion 164 may be vertically spaced apart from each other. Accordingly, the second coupling region 162 and the connection hole 133 may be provided to be double sealed.

When the first and second sealing

protrusions

163 and 164 and the connection hole 133 are sealed and the dust bag 130 is moved downward by a large flow of suction airflow, the connection hole 133 is linked thereto and moves downward. Accordingly, a gap may be generated between the first and second sealing

protrusions

163 and 164 and the connection hole 133 .

To prevent this, when the dust bag 130 is moved downward, the damping area 165 is extended downward to correspond thereto, so that the sealing between the first and second sealing

protrusions

163 and 164 and the connection hole 133 is maintained. can be

The dangling region 165 may include a convex portion 166 provided in a ring shape protruding in the radial direction of the outer circumferential surface of the sealing member 160 . The convex portion 166 may be provided to be extendable in the vertical direction when an external force is applied to the sealing member 160 in the vertical direction.

That is, the convex portion 166 maintains a convex state when no external force is transmitted to the sealing member 160 (166a), but as shown in FIG. 8 , when an external force is applied downward to the dust bag 130 , the dust bag With the movement of 130 , the convex portion 166 may be in an extended state 166b extending downward.

The convex portion 166 may be provided in an elongated state 166b that extends downward as much as the dust bag 130 is moved downward, and the sealing member 160 and the dust bag 130 may be provided to maintain their seals, respectively. Even when the dust bag 130 is moved downward, as the damping area 165 is extended as much as the moving distance of the dust bag 130, the sealing member 160 and the sealing member 160 and The sealing of the dust bag 130 may be maintained.

As described above for the understanding of the present invention, the embodiments have been described, but as those skilled in the art will know, the present invention is not limited to the specific embodiments described herein, but various modifications are made without departing from the scope of the present invention. , subject to change and substitution.
