According to the first to ninth aspects of the present invention, the lugs can be fitted and connected to the inside of the eaves gutter so that they do not appear outside the gutter ears of the eaves gutter. Aesthetics are not spoiled.

According to the first aspect of the present invention, the wall of the joint body is bent inward along the longitudinal direction of the eaves gutter to form a spring portion, so that the eaves gutter is formed. Or even if there is dimensional error or shape deformation in the eave gutter joint,
It is absorbed and eliminated by the elastic deformation of the spring portion, and the groove portion of the eaves gutter joint can be in close contact with the inner surface of the gutter main body of the eaves gutter.

In the eaves gutter joint according to the second aspect of the present invention, since the spring portion has an inverted U-shaped cross section, the elastic deformation of the spring portion becomes uniform and smooth.

According to the third aspect of the present invention, since the spring portion is formed at a position corresponding to the connecting corner between the bottom wall and both side walls of the eaves gutter, the eaves gutter or the eaves gutter joint is formed in the same manner as described above. Even if there is a dimensional error, shape deformation, or the like, it is absorbed and eliminated by the elastic deformation of the spring portion, and the lower portion of the groove portion can be brought into close contact with the inner surface of the lower portion of the gutter body portion.

According to the fourth aspect of the present invention, since the convex portion for pressing the bottom wall of the eaves gutter and the inner surfaces of both side walls is formed on the outer surface of the joint body, the convex portion is formed by the spring portion. It has the same function.Even if there is a dimensional error or shape deformation in the eaves gutter or eaves gutter joint, it is absorbed and eliminated by the pressing of the convex part, and the inner surface of the gutter main body and the outer surface of the joint main body are separated. A minute gap having a uniform thickness corresponding to the height of the projection can be formed therebetween. By using an adhesive or a caulking material together, the minute gap is filled and closed, so that there is no problem in water tightness.

In the eaves gutter joint according to the fifth aspect of the present invention, the ear locking portion has a curved portion having spring elasticity and a pressing piece. Even if the joint has a dimensional error or shape deformation, it is absorbed and eliminated by the elastic repulsive force of the curved portion, and the outer surface of the eave gutter joint can be brought into close contact with the inner surface of the eave gutter. Also, by using a pressing piece extending obliquely inward and upward from the upper end of the curved portion,
The fitting of the eaves gutter joint into the eaves gutter can be performed with good workability.

In the eaves gutter joint according to the present invention, part of the gutter ears of the eaves gutter is engaged with the concave portion formed on the upper portion of the curved portion while the curved portion has elastic repulsion. Therefore, it is possible to prevent the ear engaging portion from coming off from the groove of the gutter ear.

In the eaves gutter joint according to the present invention, since at least the wall of the curved portion at the center in the longitudinal direction of the ear engaging portion is cut out over a predetermined width, the curved portion is substantially formed. Will decrease the spring elastic force. For this reason, the joint body is pushed into the eaves gutter while deforming the ear catching part by hand, and the tip of the ear catching part engages with the groove of the gutter ear smoothly with little force. The fitting operation can be performed.

Further, by notching the wall of the pressing piece together with the wall of the bending portion, the spring elastic force of the bending portion of the ear engaging portion can be further reduced. Since a decrease in strength with respect to the force occurs, for example, by projecting a projecting piece integrally from the inner edge of the upper end of the side wall where the notch exists, the decrease in strength can be substantially reinforced, and the thermal expansion and contraction force of the eaves gutter and the snow load Deformation of the eaves gutter can be prevented.

In the eaves gutter joint according to the present invention, the wall thickness of the central part in the front-rear direction of the bottom wall constituting the joint main body, and the wall of the central part in the vertical direction of the front and rear side walls are formed. Since both thicknesses are the thickest, it is possible to prevent the bottom wall and the front and rear side walls from being lifted up, and to prevent a decrease in water stoppage.
