特徴とする気体通路の開閉弁構造。[Claims for Utility Model Registration] An opening/closing valve structure comprising a first rotating plate and a second rotating plate for shutting off and opening a gas passage such as an air flow, wherein the first rotating plate The plate is rotatably supported on both side walls of the gas passage at an end thereof in contact with one bottom surface of the gas passage, and has rising portions formed at both ends thereof facing the both sides walls, and The second rotary plate is rotatably supported on both side walls of the gas passage at a position offset from the first rotary plate at the end thereof that contacts the other bottom surface of the gas passage;
Furthermore, rising portions are formed at both ends of the side facing the both side walls, so that when each rotating plate is rotated by a predetermined amount from an upright position, both rotating plates have their free ends substantially touching each other and tilting at the same angle. An on-off valve structure for a gas passage, characterized in that a surface is formed to close the gas passage.
