PROBLEM TO BE SOLVED: To provide a ventilation member 10 for a roof excellent in ventilation performance, and capable of also preventing rainwater from intruding into an attic space.SOLUTION: A ventilation passage A is formed for communicating with an external part of an upper plate 12 from a second ventilation opening 12f by passing through a first ventilation opening 11a of a lower plate 11, a first ventilation space partitioned by an inner plate 13 and the lower plate 11, a third ventilation opening 13e of the inner plate 13 and a second ventilation space partitioned by a second ventilation surface 13c of the inner plate 13 and a first ventilation surface 12c of the upper plate 12, in order from a ventilation port 110a by a roof ventilation member 10. The second ventilation opening 12f communicating with the external part of the upper plate 12, is formed on the first ventilation surface 12c extending along a sheathing roof board 110 of the upper plate 12. The opening area of the second ventilation opening 12f can be enlarged. Thus, high ventilation performance can be provided. A louver 12g is provided in the second ventilation opening 12f, and rainwater is repelled by the louver 12g.
【課題】換気性能に優れ、かつ雨水が小屋裏に侵入するのを防止できる屋根用換気部材１０を提供すること。【解決手段】屋根用換気部材１０によって、換気口１１０ａから順にロアプレート１１の第１通気開口１１ａ、インナープレート１３とロアプレート１１で区画される第１通気空間、インナープレート１３の第３通気開口１３ｅ及びインナープレート１３の第２換気面１３ｃとアッパープレート１２の第１換気面１２ｃで区画される第２通気空間を通り第２通気開口１２ｆからアッパープレート１２の外部へと通じる通気通路Ａを形成する。アッパープレート１２の外部に通じる第２通気開口１２ｆをアッパープレート１２の、野地板１１０に沿って延びる第１換気面１２ｃに形成する。第２通気開口１２ｆの開口面積を大きくできる。そのため、高い換気性能を得ることができる。第２通気開口１２ｆにルーバー１２ｇを設け、ルーバー１２ｇで雨水を跳ね返す。【選択図】図２
