HEAT-INSULATING SPACE FORMING MEMBER ENHANCING HEAT-INSULATING EFFICIENCY

PROBLEM TO BE SOLVED: To enhance efficiency of a heat-insulating space by making a film adhere to the side of a frame in the heat-insulating space which is formed of the film and the frames on both sides. SOLUTION: When the heat-insulating space is formed with the films 4 reversed by a movable spacer 3 so as to be placed opposite, many film holders 2B made of a flexible material are vertically arranged in the frame 1. The film holder coming into contact with a guide member 5 moving according to the descent of the movable spacer 3 is bending-deformed as indicated by a symbol 2Bb, so as to permit the descent of the guide member 5. Also, the film holder, through which the guide member 5 passes, is erected again as indicated by a symbol 2Bc, so as to support the film 4 on the side of the inside wall 1B of the frame 1. Thus, the film 4 and the frame 1 adhere to each other, so that the sealability of the heat-insulating space formed of the film 4 can be enhanced without inhibiting the ascent/descent of the movable spacer 3.
