Document Type and Number:
Japanese Patent JP3160538
Kind Code:

Abstract:
PROBLEM TO BE SOLVED: To secure strength and rigidity of a roof by fitting a cover body to a vent hole of a sheathing roof board, communicating a ventilating hole of the cover body and the vent hole with each other, and discharging indoor air by passing through a clearance between roof tiles and the ventilating hole of the cover body through the ceiling.
SOLUTION: A lower part of a cover body 3 is installed on a sheathing roof board in a condition of being fitted to a vent hole of a sheathing roof board, and screw holes are bored in the four corners of a base board 2, and are screw-fiited to the sheathing roof board. In this case, after an waterproof coating is performed on a joining part of a screw part and sheathing roof felt, a waterproof effect, durability, corroding or the like are effectively prevented. A ventilating hole 7 of the cover body 3 and the vent hole of the sheathing roof board are communicated with each other, and a lower part of the cover body 3 is put in a blow-by condition, and its upper surface part is made solid. Therefore, air in a house rises downward direction of a roof tile, and the air is discharged outside by passing through the vent hole from its clearance. Therefore, moisture and intensification of heat of an attice are prevented, and a temperature rise in the house is prevented, and corrosion of the sheathing roof board and a rafter or the like can be prevented.
