Claims

[Claims for Utility Model Registration] 1. A fixed frame body in which a ventilation hole communicating between the inside and outside of a building is formed, and a door body rotatably attached to the frame body so as to open and close the ventilation hole. The door body is composed of a plate-shaped heat insulating material and a movable frame holding the heat insulating material, and at least one of the fixed frame and the movable frame has a wall around a vent. Airtight material is installed along the
The other side is formed with a protrusion that can be crimped onto the airtight material, and the fixed frame has a protrusion that allows the movable frame to be fastened to the fixed frame with the door body blocking the vent. An underfloor ventilation opening for a building, characterized in that it is equipped with a fastening member for fixation. 2. A fixed frame body in which a ventilation hole communicating between the inside and outside of the building is formed, and a door body rotatably attached to the frame body so as to open and close the ventilation hole, the door body being , consisting of a plate-shaped heat insulating material and a movable frame that holds the heat insulating material, and either the fixed frame or the movable frame has a built-in permanent magnet along the periphery of the vent. An underfloor ventilation opening for a building, characterized in that an airtight material is attached to the other frame, and a frame press-contact part made of a magnetic material that can be pressed to the airtight material is formed on the other frame. 3. A fixed frame body in which a ventilation hole communicating between the inside and outside of the building is formed, and a door body rotatably attached to the frame body so as to open and close the ventilation hole, the door body being , consisting of a plate-shaped heat insulating material and a movable frame that holds the heat insulating material, and an airtight material is attached to at least one of the fixed frame and the movable frame along the periphery of the vent. The movable frame has a flat surface that can be crimped to the airtight material, and the movable frame has a flat surface that can be pressed against the airtight material, and the movable frame is attached to the fixed frame with the door body blocking the vent. An underfloor ventilation opening for a building, characterized in that it is equipped with a tightening member for tightening and fixing. 4.
