  Since the ridge side end 101 of the one-sided roof 100 is located at the apex of the roof, it is easy to receive strong winds, and sometimes receives wind blown from under the eaves. Rainwater may be blown by strong winds and enter the inside of the wing decorative plate 102 from the vent hole 102d.

Since the air holes 102d are formed in the lower covering portion 102c of the wing decorative plate 102, wind and rain rarely blow directly on the surface of the air holes 102d, and a large amount of rainwater does not enter the inside of the wing decorative plate 102. However, even if it is a small amount, rainwater that has entered from the air holes 102d adheres to the surface of the base material 101a of the ridge side end portion 101 surrounded by the ward decorative plate 102, thereby accelerating deterioration or corrosion of the base material 101a. It may cause it.
As long as the vent hole 102d is exposed to the outside, it is inevitable that rainwater enters the inside of the wing decorative plate 102 from the vent hole 102d. However, in order to suppress the progress of deterioration of the base material 101a due to the attachment of rainwater. Therefore, it is important to provide a means for making it difficult to attach rainwater to the base material 101a inside the wing decorative plate 102.

  In view of such problems of the prior art, the present invention provides a ventilation structure that is attached to a ridge side end of a single ridge roof. It makes it a subject to comprise so that it may be hard to adhere to a side edge part structural member.

In order to solve the above problems, the present invention has an upper covering portion covering the upper side of the ridge side end portion, a side covering portion covering the side portion, and a lower covering portion covering the lower portion at the ridge side end portion of the single ridge roof. A ventilation of a single ridge roof having a configuration in which a building veneer plate in which a plurality of ventilation holes are formed is attached to the lower covering portion and the outside of the house and the attic space are communicated with each other through the ventilation holes of the wing veneer plate In the construct:
Above the vent hole formed in the wing decorative plate, a draining plate with the ridge side end bent downward is disposed facing the vent hole, and the space immediately above the vent hole is covered with the draining plate. characterized by having a configuration in which vent passage narrow is provided between the side cover portion inner surface of the end portion and the ridge decorative plate folded downwardly of the deflector board.

According to the ventilation structure of the said structure, an outside air can be taken in into an attic space and the attic space can be ventilated through the ventilation path formed between the vent hole provided in the building decorative board and the attic space.
In addition, a draining plate is arranged above the vent hole, and this drainer plate functions as a shielding plate that prevents inflow of rainwater that has entered from the vent hole into the attic space of the rainwater. The rainwater does not adhere to the base material at the end of the ridge side or flows into the attic space, and deterioration of the base material due to the attachment of rainwater and the progress of corrosion can be suppressed.
Rainwater that has been blown by the strong wind and entered from the vent hole collides with the draining plate, flows down along the surface, and is discharged to the outside through the vent hole located below the draining plate. In addition, the outside air that has flowed in from the ventilation holes flows into the attic space through a ventilation path that is a narrow gap between the end of the draining board and the inner surface of the side covering portion of the wing decorative board.

  In the ventilation structure having the above-described configuration, the draining plate can be formed separately from the wing decorative plate and attached to the ridge side end portion, but the lower covering portion of the wing decorative plate is disposed above the lower end portion. If a lower mounting surface part that is folded back to the lower end of the ridge side end is fixed and a draining plate is integrally fixed to the lower mounting surface part, a ward decorative plate is attached to the ridge side end. It is preferable that a draining plate can be installed by attaching.
