PROBLEM TO BE SOLVED: To provide an air inflow check valve, easy in opening-closing for making much air flow in an air circulation layer, and preventing a backflow of the air, in the air inflow check valve used for a building inside air circulation mechanism equipped with the air circulation layer for circulating the air in a building.SOLUTION: An air inflow check valve is composed of a cylindrical fin seat and a fin body of becoming a cover, and the fin body is constituted of a cover part, a main weight part, a tail weight part and a shaft, and the fin body is rockably journaled to a bearing of the fin seat via the shaft, and an auxiliary weight part and a lift generating recessed slope for generating lift by passing of an air current, are provided on an outside surface of a cover part of the fin body.SELECTED DRAWING: Figure 1
【課題】建造物内において空気を循環させるための空気流通層を装備した建造物内空気流通機構に用いる空気の流入逆止弁であって、空気流通層内に多くの空気を流入させるとともに空気の逆流を防ぐための、開閉容易な空気流入逆止弁を提供する。【解決手段】円筒状のフィン座と、蓋となるフィン本体と、からなり、前記フィン本体は、蓋部と、メインウエイト部と、テールウエイト部と、シャフトと、から構成されており、フィン本体を、シャフトを介してフィン座の軸受に揺動自在に軸装するとともに、フィン本体の蓋部の外側面に、補助ウエイト部と、気流の通過により揚力の生じる揚力発生凹スロープと、を設けた構成である【選択図】 図１
