ABSTRACT:
A base end of the foldably stretchable accordion screen 10 is fixed to an inner portion of the receptacle box frame 13 which constitutes one of the side frame members of a screen support frame structure, and the movable frame is attached to the fore end of the screen slidably along the screen support frame for opening and closing the screen toward and away from the receptacle frame. Fixed to the movable frame 18 are the ends of a plural number of tension cords 20a to 20d which are folded around turn-guide members 21b to 21d and 22 on the side frame member. A pendant weight 24 is attached to the other ends of the tension cords which are hung down in the side frame member, thereby to apply to the movable frame a biasing force in the screen opening direction. The pendant weight 24 is associated width a resistant mechanism 26 which serves to buffer the descending motion of the pendant weight as it reaches its lower stop position.
