Abstract

A torque hinge (100; 200) comprises a spring component (1; 11), a mounting component (3), fixing components (4, 5; 14, 15) and a rotational torque equalizing component (6; 16). The spring component (1; 11) has an insertion hole (H1; H2) into which a shaft component (2) is inserted. The spring component (1; 11) is bent so as to form a sleeve spring part (1A; 11A) which generates rotational torque with the shaft component (2), and to form first and second spring plate parts (1B, 1C; 11B, 11C) which extend from the sleeve spring part (1A; 11A) while maintaining a certain distance from each other. The mounting component (3) contacts one side of one of the first or second spring plate parts (1B, 1C; 11B, 11C). The rotational torque equalizing component (6; 16) contacts the opposite side of the other of the first or second spring plate parts (1B, 1C; 11B, 11C). The fixing components (4, 5; 14, 15) fix the spring component (1; 11) to the mounting component (3), while also regulating the amount of rotational torque generated between the sleeve spring part (1A; 11A) and the shaft component (2). The first and second spring plate parts (1B, 1C; 11B, 11C) are wedged between the rotational torque equalizing component (6; 16) and the mounting component (3). The first and second spring plate parts (1B, 1C; 11B, 11C) are compressed through the rotational torque equalizer component (6; 16), and fixed to the mounting component (3) by the fixing components (4, 5; 14, 15).
