That is, when the adhesive is used to connect the strainer 2 and the gutter member 3 and to connect the gutter members 3 to each other, for example, the strainer 2 exposed on the floor surface 1a is corroded or externally exposed. It is necessary to replace the strainer 2 for repair when it is deformed due to the impact of. In this case, the bonded portion between the strainer 2 and the gutter member 3 must be broken. However, such joints are often not exposed from the building, so this replacement work is time-consuming, time-consuming, and practically impossible in relation to the building. . Even if the adhesive is not used, special fixing means must be used on the wall of the building to prevent the members from coming off, and therefore, due to the structure of the building, installation work and removal There was a problem that the work was extremely difficult, and even if the work was possible, it took time to work.

The present invention has been made to solve the above problems, and in particular, to provide a drainage gutter for surely and quickly attaching / detaching work of a strainer and a gutter member. To aim.
