It is made by rotatably supporting via. At this time, only by inserting the shaft 7 into the hinge body 6, the shaft 7 is prevented from coming off. That is, when the large diameter portion 7a of the shaft 7 approaches the open end surface of the shaft insertion hole 10, the elastic claw 11 temporarily elastically retracts to the side to allow passage of the large diameter portion 7a. After the passage, the elastic claw 11 elastically returns to the original position, and the tip of the elastic claw 11 prohibits the movement of the shaft 7 in the extracting direction. In order to make the support member hinge the door 5 using such hinges 1A and 1B, first, the positioning projections 13 projecting from the upper part 6b and the lower part 6c of the hinge body 6 are attached to the front plate 2 of the door 5. The upper and lower edges 2a and 2b of the front plate 2 of the door 5 and the bent portions 21, 22 and 23 of the side edge 2c on the hanging side are positioned after being aligned with the holes 24 formed in the upper edge and the lower edge. Attach hinges 1A and 1B to the corners. At this time, the hinge piece 8 pivotally attached to the hinge main body 6 has the hinge plate 8 of the door 5 through the hole 25 formed near the upper and lower corners of the side edge 2c of the plate 2 of the door 5. It is made to project outside the side edge 2c. Next, in the hinge body 6 of the hinge 1A arranged in the upper corner portion, the upper edge bent portion 21 of the door 5 is screwed into the screw hole 9a.
The screw 14 that is fastened by the screw 14 that is screwed to the screw 14 and that has the side edge bent portion 23 screwed into the screw screw holes 9b and 9c.
Then, the back plate 3 is attached by screws 14 screwed into the screw screw holes 9d. In addition, the lower edge bent portion 22 of the door 5 is fixed to the hinge body 6 of the hinge 1B arranged at the lower corner portion by the screw 14 screwed into the screw threaded hole 9d, and the side edge bent portion is also fixed. 23 are screwed holes 9b and 9c
The back plate 3 is fixed by screws 14 which are screwed together, and the back plate 3 is further fixed by screws 14 which are screwed into the screw screw holes 9a. In this way, the hinge 1 is fixed to the door 5 while mounting and fixing the back plate 3 of the door 5 on the back side of the front plate 2. The door 5 can be assembled to the support member via the hinge 1 by attaching the hinge piece 8 projecting outward of the side edge 2c on the suspension side of the front plate 2 to the support member.
