PURPOSE:To facilitate control by forming a recess having an opening on the other hinge plate side to a part of one hinge plate, inserting a part of a plate body into the recess to connect to a hinge plate having the recess, and loading a projection to the other hinge plate. CONSTITUTION:A hinge is constituted of hinge plates 6, 7 and a plate body 9 inserted into a recess 8 formed on the plate 7. While a C ring 12 is loaded between two bobbins 10 and 11 provided to the plate 6, a bobbin 14 smaller than the internal diameter of a ring 12 is formed to the end of the plate body 9. After that, the ring 12 loaded with the bobbin 14 is placed between the bobbins 10 and 11, and after bolts 17 and 18 are screwed each other, the plate 6 is fixed to a column side. Then, the plate 7 is fixed to a door side, the plate body 9 is inserted into the recess 8 to fix, and mounting work is completed. The plate body 9 is moved up and down by the bolts 17 and 18 and, at the same time, the plate body 9 is controlled in the direction of the thickness with a control screw 22. Accordingly, control can be easily made. |
