Claims

[Scope of Claim for Utility Model Registration] A rotatable take-up shaft stored in the ceiling, a screen that is wound up on the take-up shaft, and a seat plate is attached to the tip of the screen that is rewound and retracted from the ceiling surface. A movable screen comprising a movable rail that includes rollers that engage with the seat plate and can accommodate the seat plate that swings horizontally and vertically in conjunction with the rise and fall of the screen, at both ends of the front and rear sides of the seat plate. and an engagement member provided on the inner side of the movable rail that comes into contact with the locking protrusion from the inner side of the downward path of the locking protrusion when the movable rail is in a vertical state, A swing regulating mechanism for a movable rail in a movable screen, characterized in that an engaging member of the movable rail is locked by a locking protrusion on a seat plate to restrict swinging of the movable rail beyond a vertical state.
