Abstract
A torque hinge or torque limiter includes external and internal cylindrical members that are capable of relatively rotating, and a coil spring placed between the external and internal cylindrical members. A first circumferential portion is formed on a front-end side of the inner periphery of the external cylindrical member. A second circumferential portion is formed on a rear-end side of the outer periphery of the internal cylindrical member. The torque value that blocks the rotary torque of the external or internal cylindrical member in a first arbitrary direction is set by pressing the first circumferential portion against the outer circumferential portion of the coil spring. The torque value that blocks the rotary torque of the external or internal cylindrical member in a second arbitrary direction is set by pressing the second circumferential portion against the inner circumferential portion of the coil spring.
