通気部材１０は、下面部１４によって通気部材１０の下面を覆っている。下面部１４の軒先側端１４ｆと風雨誘導板２０の誘導板下端２０ｄとは連続して形成している。
前面部１１には、前面部１１の前面下端１１ｄから連続して風雨誘導板２０に至る前面延出部１１Ｃを設けている。
The ridge ventilation device of this embodiment has a ventilation member 10 which forms a front opening 11A in the front portion 11 which is located on the eaves side and a rear opening 12A in the rear portion 12 which is located on the top side of the roof surface, a wind and rain guide plate 20 which is located at a predetermined distance from the front portion 11 and faces the front opening 11A, and a top cover 30 which covers the upper surface of the ventilation member 10 and forms a ventilation passage between the rear opening 12A and an opening 5 (see Figure 2) formed in the sheathing board 3 (see Figure 2).
The lower surface of the ventilation member 10 is covered by the lower surface portion 14. The eaves side end 14f of the lower surface portion 14 and the guide plate lower end 20d of the wind and rain guide plate 20 are formed continuously.
The front portion 11 is provided with a front extension portion 11C that continues from the front lower end 11d of the front portion 11 to the wind and rain guide plate 20.
前面部１１には、前面開口１１Ａの上方に、前面垂下部１１Ｂを形成し、前面開口１１Ａの下端を前面下端１１ｄに至らせている。
背面部１２には、背面開口１２Ａの下方に、背面立上部１２Ｂを形成している。背面部１２の上端は、折り曲げられて天面カバー３０の下面に沿って延長され、更に下面部１４の方向に折り曲げられて背面垂下部１２Ｃを形成している。
前面部１１の上端と天面カバー３０とを連続して形成し、背面部１２の下端と下面部１４の後端部とを連続して形成している。
The front surface portion 11 has a front hanging portion 11B formed above a front opening 11A, and the lower end of the front opening 11A extends to a front lower end 11d.
A rear rising portion 12B is formed below the rear opening 12A in the rear portion 12. The upper end of the rear portion 12 is bent and extended along the lower surface of the top cover 30, and is further bent toward the lower portion 14 to form a rear hanging portion 12C.
The upper end of the front surface portion 11 and the top cover 30 are formed continuously, and the lower end of the rear surface portion 12 and the rear end portion of the bottom surface portion 14 are formed continuously.
天面カバー３０と前面部１１とを折り曲げによって形成するとともに前面延出部１１Ｃを設け、通気部材１０の下面を覆う下面部１４の軒先側端１４ｆと風雨誘導板２０の誘導板下端２０ｄとを連続して形成することで、通気部材１０と風雨誘導板２０との強度を高めることができる。 The strength of the ventilation member 10 and the wind and rain guide plate 20 can be increased by forming the top cover 30 and the front portion 11 by folding, providing a front extension portion 11C, and forming the eaves side end 14f of the lower portion 14 that covers the lower surface of the ventilation member 10 and the lower end 20d of the guide plate of the wind and rain guide plate 20 in a continuous manner.
前面部１１と風雨誘導板２０との間には、前面部１１の前面下端１１ｄから連続し、前面下端１１ｄで軒先側に折り曲げて風雨誘導板２０に至る前面延出部１１Ｃを設けている。
前面延出部１１Ｃの前端の一部には係止片１１Ｄを備えている。誘導板下端２０ｄには水抜き孔２１が形成されている。係止片１１Ｄは水抜き孔２１に係止する。水抜き孔２１に係止片１１Ｄを係止させることで、通気部材１０の強度を高めることができ、前面延出部１１Ｃから水抜き孔２１への雨水をスムーズに流すことができ、軒先側から吹き上げられる雨水が水抜き孔２１から浸入することを係止片１１Ｄによって阻止することができる。
Between the front portion 11 and the wind and rain guide board 20, a front extension portion 11C is provided which continues from the front lower end 11d of the front portion 11, bends at the front lower end 11d toward the eaves, and reaches the wind and rain guide board 20.
A locking piece 11D is provided at a portion of the front end of the front extension 11C. A drainage hole 21 is formed at the lower end 20d of the guide plate. The locking piece 11D locks into the drainage hole 21.

従って、水抜き孔２１の両側外方に係止片１１Ｄが配置されることになり、軒先側から吹き上げられる雨水が水抜き孔２１から浸入することを係止片１１Ｄによって阻止することができる。
係止片挿入孔１４Ｈの中心部には、係止片抑え突起１４Ｔを形成している。係止片抑え突起１４Ｔによって係止片１１Ｄを水抜き孔２１に押し付けることができ、係止片１１Ｄと水抜き孔２１とを密着させることができる。
係止片１１Ｄは、根元幅１１Ｗａよりも先端幅１１Ｗｂを狭くしている。従って、係止片１１Ｄを係止片挿入孔１４Ｈに挿入しやすく、係止片１１Ｄと係止片挿入孔１４Ｈとの隙間を無くすことができる。
係止片１１Ｄの先端幅１１Ｗｂを水抜き孔２１の幅よりも広くしているので、水抜き孔２１の両側方に係止片１１Ｄが配置され、軒先側から吹き上げられる雨水が水抜き孔２１に導かれることを防止できる。
An engaging piece insertion hole 14H that is continuous with the drainage hole 21 is formed at the eaves side end 14f of the underside portion 14.
As shown in Fig. 1(d), the locking piece insertion holes 14H extend outward on both sides beyond the drainage holes 21. The locking piece insertion holes 14H are blocked by inserting the locking pieces 11D (Fig. 1(c)).
Therefore, the locking pieces 11D are arranged on both outer sides of the drainage hole 21, and the locking pieces 11D can prevent rainwater blown up from the eaves side from entering through the drainage hole 21.
A locking piece pressing protrusion 14T is formed in the center of the locking piece insertion hole 14H.
