A drainage system was installed.

Note that the overhanging member refers to a plate-shaped member on which no eave gutter is installed, such as a horizontal roof provided above a window, veranda, or doorway, or a veranda or balcony floor.

(Function) Therefore, in the drainage device of the present invention, by employing the above-mentioned means, a rectangular cylindrical joint (elbow, socket, etc.) can be locked and attached to the locking portion of the locking ring. Alternatively, a cylindrical joint can be attached to the inner flange of the locking ring.

Furthermore, since the locking ring is rotatably provided on the outer periphery of the locking cylinder, after the joint is attached to the locking ring, the direction of the joint can be adjusted by rotating integrally with the locking ring.
