The first passage forming member 15 is also formed by bending a rectangular metal plate. The support portion 24 is formed by being bent at a constant width in parallel with one side, and this portion is hooked on the purlin support member 9 as shown in FIG. 2 and fixed by being sandwiched between the purlin 2 and the purlin support member 9. Is done. A plurality of rectangular first ventilation openings 32 are formed in a horizontal row on a surface of a portion extending obliquely downward from the bent portion of the support portion 24. A surface that is bent downward and extends from the surface where the first ventilation port 32 is formed is the first ventilation passage forming portion 25, and the first ventilation passage forming portion 25 is between the base member and the purlin support member. Is the first ventilation passage. The portion bent from the lower end of the first ventilation passage forming portion 25 toward the base member is a mudguard portion 26, the tip of which is fixed to the roof of the first member 12 of the base member as shown in FIG. The length and the bending angle are set so as to approach the vicinity of the boundary between the part and the rising part. The mudguard 26 prevents the mud used to fix the roof tiles from entering the space through which the exhaust of the base member passes, thereby lowering the ventilation function.
