PROBLEM TO BE SOLVED: To provide a door structure than can easily and freely change its opening/closing direction upon or even after moving into the house. SOLUTION: Inner frames 4 and 40 which has removable stopper 41b, a tubular part 41c, and a 41a, locking claw are attached to fixing the grooves 1a and 10a of the right and left vertical outer frames 1 and 10, through spaces 5 and 50, and a door body D is installed on the tubular part of 41c of the hanging side through a hinge 6. In case of changing the opening directions by dividing the door frame into vertical outer frames 1 and 10 and inner frames 4 and 40, the opening direction of the inner frames D can be easily changed by pulling out the inner frames from the vertical outer frames and changing the orientation of the inner frames in accordance with the desired direction, or replacing the inner frames with more adequate ones for the required opening direction to insert the inner frames into the fixing grooves 1a and 10a of the vertical outer frames. |
