Claims

[Scope of Claim for Utility Model Registration] An outdoor casing having an intake window and an exhaust window on a side wall; a first air filter provided in the intake window of the outdoor casing; disposed so as to cover the first air filter; a first hood extending to the outside of the outdoor casing and forming an intake passage; an exhaust fan provided at an exhaust window of the outdoor casing; a first hood extending to the outside of the outdoor casing and arranged to cover the exhaust fan; , a second forming an exhaust passage
a first ventilation regulating valve rotatably connected to the intake passage in the first hood via a first hinge; fixed to the other end of this first ventilation regulating valve;
an elastic member that presses the ventilation adjustment valve of the hood so that the intake passage opens; and a second hood whose end is rotatably connected to the exhaust passage in the second hood via a second hinge. A ventilation structure for an outdoor enclosure, comprising: a ventilation adjustment valve; and means for attaching the second ventilation adjustment valve so as to block an exhaust passage by external wind pressure.
