  • the friction with the outer wall, the air in the space between the tub 20 and the drum 30 is more difficult to flow out to the second communication portion (630).
  • the length of the second communication portion 630 protruding toward the outer circumferential surface of the drum 30 is also shorter than the shortest distance between the tub 20 and the drum 30. This is because the drum 30 and the second communication unit 630 should not contact due to the vibration generated when the drum 30 is rotated.
