The openings formed between the left and right columns, the left and right columns, and the outer wall are entrance eaves in which a partition portion for partitioning the external space and the internal space is installed, and the roof is on the left and right sides. A roof frame composed of a frame and front frames attached to the left and right side frames, a decorative material arranged so as to cover the peripheral surface of the roof frame, and a roof material installed in the roof frame. It is provided with an eaves roof material that is installed in the roof frame and forms an in-roof space between the roof material and the roof material, and the left and right side frames are a side frame main body supported by the left and right columns and the side. A side frame attachment in which the frame body is connected to the eaves roof material is provided, and an external opening is formed between the partition portion, the decorative material, and the eaves roof material connected to the side frame attachment, and the eaves roof material is formed. Has an internal opening communicating with the internal space of the entrance eaves, and the roof is characterized by having an external opening, an internal space in the roof, and an outside air introduction path through the internal opening.
According to the entrance ridge of the present invention, the pressure difference between the outside space and the inside space can be reduced by introducing the outside air from the outside space to the inside space to the inside space through the outside air introduction path configured in the roof. It is possible to suppress the infiltration of rainwater into the internal space while being drawn from the external space due to the pressure difference, and it is possible to improve the watertightness.
Further, since the rainwater that is about to be blown into the external opening in rainy weather is returned to the outside by the eaves ceiling material, it is possible to make it difficult for rainwater to enter from the external opening.

The second gap may be formed, and the outside air introduction path may be configured to pass through the first gap and the second gap.
According to such a configuration, it is not necessary to process the ventilation holes in the side frame attachment, and the outside air introduction path can be easily configured.

In the entrance eaves of the present invention, the lower edge portion of the decorative material may be arranged below the side frame attachment.
According to such a configuration, the rainwater sprayed on the decorative material flows along the finding surface of the decorative material and drips downward from the lower edge, so that the rainwater may infiltrate into the first gap from the external opening. Can be reduced.

In the entrance eaves of the present invention, the eaves material is configured by arranging a plurality of eaves panels along the side frame side by side, and the girder material is a girder material on which the end portion of the eaves panel is placed. An attachment may be attached, a concave groove opened downward may be formed in a connecting portion between the plurality of eaves panels, and the internal opening may be formed between the end face of the concave groove and the girder attachment. ..
According to such a configuration, since the end of the eaves panel is covered with the girder attachment, the internal opening is not visible even when looking up from the internal space of the entrance eaves, and the design is maintained. The outside air introduction path can be configured as it is.
