の換気扇。[Scope of Claim for Utility Model Registration] (1) A ventilation fan body consisting of a blower and a casing covering it is attached to a mounting plate attached to an outdoor wall, and an open ventilation opening is opened on the indoor wall through the wall. In a ventilation fan that sucks indoor air through a ventilation duct and exhausts it outdoors,
A part of the ventilation duct is provided with an opening that can be viewed into the attic space, and this opening is opened by the suction action generated in the ventilation duct during ventilation operation, and usually by the urging force of an elastic member. A ventilation fan characterized by being equipped with an opening/closing damper that closes the opening. (2) The ventilation fan according to claim 1, which is a utility model, characterized in that the urging force of the elastic member that urges the opening/closing damper toward the closing side can be adjusted in strength.
