PROBLEM TO BE SOLVED: To solve the problem of being inconvenient due to requiring to taking off a slipper outside an opening radius of a door, since the slipper taken off when opening and closing the door, strikes on the door opened to this side, since clearance with a floor is little, in a conventional opening door. SOLUTION: The opening door is provided with a device for vertically sliding so that a lower part of the door clears the slipper, when opening and closing the door. COPYRIGHT: (C)2006,JPO&NCIPI
