CONSTITUTION: An outer cylinder 3 is positioned at a fixed interval from the outside of an inner cylinder 2 having a culture space 21 in the interior and the lower end part between the inner cylinder 2 and the outer cylinder 3 is closed with a bottom plate 4 to constitute a case material 1 provided with a ring-shaped water housing chamber 5 at a part surrounded by the inner cylinder 2, the outer cylinder 3 and the bottom plate 4. The inner cylinder 2 is provided with a great number of drain holes 22 communicating with the water housing chamber 5 and the culture space 21 and water in the water housing 5 flows only into the inner cylinder 2. |
