PURPOSE: A hinge is provided to prevent the twisting of a door or window since there is no abrasion on the contact area of a fixed support and a rotary support. CONSTITUTION: A hinge(1) comprises a fixed hinge portion(10), a rotary hinge portion(20), a first washer(40) and a second washer(50). Hinge shafts(30) are inserted into the fixed and rotary hinge portions. The first and second washers are installed between the fixed and rotary hinge portions. The first washer is coupled to one end of fixed supports(12,13), which faces the rotary support. The second washers are coupled to both ends of a rotary support(22) to rotate in cooperation with the rotary support. The second washer rotates in a state of making contact with the first washer. |
