不正取外しが完全に防止されるのである。(Effect of the invention) As described above, in the hinge of the invention, the fixed side member 2
Since the cover members 9a and 9b are fixed to the fixed side member 2, which always cover the fixing screw 11 and prevent the rotating side member 3 from approaching the fixing screw 21 when the door is closed, the door 3 is not in the closed state. In this case, all the fixing screws 11, 21 cannot be removed, and unauthorized removal of the hinge is completely prevented.
