[0002]

2. Description of the Related Art In a wooden building or the like, a roof is generally provided so as to protrude from an outer wall surface to form an eave. Such eaves prevent rain from directly falling on the outer wall, thereby reducing durability and preventing the outer wall from becoming dirty. Also,
In addition to preventing rainwater from directly hitting the opening where the opening is located, it also has a role in controlling sunlight.

[0003] In a wooden building, a roof is generally provided with a rafter on a main building or an eave, and a roofing material is struck thereon to cover a roofing material. The eaves are formed by providing the rafters so as to protrude from the outer wall surface.

[0004]

However, in a portion where the rafters of the eaves can be provided so as to be continuous from the outer wall surface to the inside of the building, the eaves may not drop even if the rafters are supported so as to project. Although it is small, it is difficult for the rafter to support the weight of the eaves when the rafter cannot be a member that continues inside the outer wall surface. In other words, if the outer wall of the first floor and the second floor are at the same position, the rafters must be cut off at the outer wall, and it is necessary to resist the large bending moment acting on the root of the eave. Means are required. If this is not sufficient, problems such as the eaves hanging over the years will occur. In addition, the provision of a structure for supporting the eaves often makes the back of the eaves less comfortable, and often requires much effort to form the eaves.

[0005] The present invention has been made in view of the above problems, and its object is to firmly support the eaves,
The purpose is to prevent sagging and to form the eaves easily and easily.
