  • the direction in which the bell mouths 12, 12A, 14, 14A, and 14B are opened is not necessarily perpendicular to the vertical direction.
  • a first bell mouth which is opened toward the first direction D1 perpendicular to the vertical direction, or a third direction having the component in the first direction D1 and the component of the lower side V in the vertical direction, and a second bell mouth which is adjacent to the lower side V in the vertical direction than the first bell mouth and is opened toward the second direction D2 perpendicular to the vertical direction, or a fourth direction having the component in the second direction D2 and the component of the lower side V in the vertical direction, and a lower end in the vertical direction of the first bell mouth, and an outer peripheral surface of the second bell mouth in the lower side V in the vertical direction of the lower end may together cooperate to show a water conducting path conducting the liquid to the vertically lower side.
  • the upper end 18, 18A, or 18B is not necessarily the upper end in the vertical direction of the second bell mouth 14, 14A, or 14B itself.
  • the lower end 16 or 16A in the vertical direction of the first bell mouth 12 or 12A is not necessarily located in the upper side -V in the vertical direction of the upper end in the vertical direction of the second bell mouth 14, 14A, or 14B itself.
  • the drawings show the aspect in which the magnitude in plan view along the first direction D1 of the first bell mouth 12 or 12A and the magnitude in plan view along the second direction D2 of the second bell mouth 14, 14A, or 14B are approximately equal with each other.
  • the first bell mouth and the second bell mouth do not necessarily have the approximately equal magnitude with each other.
