In a semi-cylindrical resin film tunnel in which these frames 1 and 2 are coated with a resin film 3 to cover the ridges 8, a shape that curves at a predetermined temperature is stored at the root portion of the arc-shaped frames 1 and 2. An elongated member 5 made of a shape memory alloy is disposed, and the elongated member 5 is
The bendable lower end of the resin film 3 faces the hem of the resin film 3, and the elongated member 5 is always extended along the arcuate frames 1 and 2, and the temperature inside the tunnel is kept at a predetermined value. The resin film tunnel is characterized in that when the elongated member 5 reaches the destination, the elongated member 5 curves due to recovery of the memorized shape and rolls up the hem of the resin film 3, thereby opening the tunnel. ventilation system.
