The ventilation ridge tile 3 is attached to the support metal fitting 17 by attaching the perforated plate 20 fitted into the tile ventilation opening 5 to the support metal fitting 17 with bolts 21 and nuts 22. The tile ventilation opening 5 and the ventilation opening 3 are shifted in position in the ridge length direction to prevent rainwater passing through the perforated plate 20 from directly entering the ventilation opening 3 of the rain cutter plate 2. Further, a drain baffle plate 23 is suspended from the perforated plate 20 to prevent rainwater entering from the perforated plate 20 from being blown toward the vent 3 side and scattered.

As shown in FIG.
It is fixed as a rising peripheral wall on the periphery. Cylindrical body 2
A rubber packing 25 is fitted onto the upper part of the rain cover 4, and the lower end surface of the rubber packing 25 is pressed against the rain cutting plate 2 to maintain sealing performance. A water return flange 26 is provided outwardly from the upper peripheral edge of the cylindrical body 24. The cylindrical body 24 and the water return collar 26 are made of synthetic resin and are integrally formed. In this way, the cylindrical body 24 serving as the rising peripheral wall prevents the rainwater passing through the perforated plate 20 from being blown into the vent 3 by the wind blown from the perforated plate 20, and the rainwater adhering to the rubber gasket 25 is prevented from being blown into the vent 3 by the wind blowing from the perforated plate 20. The water return flange 26 can prevent water from being blown up and entering the vent 4.
