Abstract
Abstract The present invention relates to a movable partitioning panel which can be moved along a hanger rail disposed in a ceiling to thereby form a suitable partitioning wall within a room. Runner devices arranged within the hanger rail are rotatable irrespective of the attitude of a panel body and can be smoothly moved with the hanger rail. In addition, the panel body can be simply moved at a branch path, a bend in the path and the like through upper and lower guide rollers and a controller device for the runner devices. Furthermore, the panel body in its horizontal attitude can be closely positioned with respect to a fixed wall.
