For example, the long hole of the present invention may be provided in the valve body, and the rotating shaft portion of the present invention may be provided in the drainage device body. At this time, the rotating shaft of the present invention is formed separately from the drain device body, and is inserted into the hole provided in the drain device body and the long hole provided in the valve body.

In the above embodiment, there are two receiving ports OP, the number of which can also be one or more than three.

In the above embodiment, the first inclined surface 101 is formed as a flat surface, but it is not limited to this, as long as it is inclined downward from the outer edge of the lower surface 100 to the center of the lower surface 100, it may be Formed as a curved surface.

The drainage device of the present invention is a drainage device that discharges water accumulated in a frame material, and includes: a cylindrical body having a drainage channel penetrating in a vertical direction; a valve body that is provided in the drainage channel, and It can be moved to the normal position, the valve opening position and the valve closing position respectively. A water-retaining surface against which the valve body abuts is provided on the inner peripheral surface of the cylindrical body, between the cylindrical body and the valve body one of One is provided with an elongated hole; the other of the cylindrical body and the valve body is provided with a rotating shaft inserted into the elongated hole, and the normal position is that the rotating shaft is located at the long On one end side in the longitudinal direction of the hole, the gap between the water blocking surface and the valve body is the position of the first gap; the valve opening position is the position of the valve body positioned to the normal position when the valve body rotates The shaft part rotates in the center, and the gap between the water blocking surface and the valve body is the position of the second gap that is larger than the first gap; the valve closing position is that the rotating shaft part is located at the On the other end side in the longitudinal direction of the long hole, the valve body abuts against the position of the water blocking surface.

In the present invention, the valve body is usually positioned to the normal position based on its own weight. In addition, the valve body positioned in the normal position receives a load due to the water that penetrates into the drainage channel through the receiving port, rotates around the rotating shaft portion, and is positioned to the valve opening position.

Here, in the normal position, the gap (first gap) between the water blocking surface and the valve body is smaller than the gap in the valve opening position (second gap). In other words, since drainage is not required in a normal state, the gap (first gap) between the water blocking surface and the valve body can be made relatively small. Therefore, it is possible to prevent outdoor wind from flowing into the room through the drainage device (the gap) under an environment that includes a windless state of natural wind (for example, wind of 12 m/s or less) blowing.

In other words, you can block The water surface is arranged at a position where the valve body does not mechanically interfere with the valve body when the valve body rotates. Therefore, when the valve body is positioned to the valve-closing position, the abutment between the valve body and the water-retaining surface can be reliably implemented, and the water-retaining performance at the valve-closing position can be improved.

Furthermore, regarding the present invention, in the drainage device, the elongated hole is provided in the cylindrical body, and the rotating shaft is provided in the valve body.
