PROBLEM TO BE SOLVED: To provide a shutter device for a door, which stabilizes a shutter lifting/lowering operation by simplifying a structure, which makes operability light and proper, and which enables maintenance by improving the workability of attachment to a hinged door.SOLUTION: When the hinged door D is closed and locked for the use of a room such as a toilet, a thumb-turn knob of a lock K is turned in a normal direction, and a cam lever 21 is turned to a turning position to put a connecting protrusion 21d into an upward inclined attitude. In this case, in the shutter device R for the door, a link 74 of a link unit L is lifted by a height obtained by the upward inclination of the connecting protrusion engaged with its joint 76, depending on its rotational direction; and a leg member 77 recedes from above a protrusive piece portion 60c of a swing rod 60 of the shutter unit C. Thus, a working rod makes a locking portion 60b on the other side of the protrusive piece portion tilted downward by gravity. This makes the shutter lowered to a screening position by the guidance of the guide means G so as to screen a gap S between the hinged door and a floor surface F. |
