MEMBER FOR FORMING HEAT-INSULATED SPACE

PROBLEM TO BE SOLVED: To make a film adhere tightly to a frame body without causing a hindrance to the stretch and rewind of the film in a heat-insulated space formed of the film and the frame bodies on both sides. SOLUTION: The heat-insulated space is formed of the films facing each other in the state of being turned upside down by an ascending/descending member 51, and sealed with the frame bodies 2 on both the sides of the film. Pressing members are arranged in the frame bodies 2, respectively; U-shaped bodies 1Ba of the pressing members are brought into pressure contact with inner wall surfaces of the pressing members 2, respectively; and thus, side edges of the two opposed films are brought into pressure contact with the inner wall surfaces 2a to seal the space, respectively. Additionally, a separation member 3 formed at the end of the ascending/descending member 51 makes the U-shaped body 1Ba separated from the inner wall surface 2a by being folded in the separation member 3, in a portion in which the separation member 3 is positioned, and prevents the U-shaped body 1Ba from being a hindrance to the stretch and unwind of the film.
