Abstract
A torque hinge is such that a driven-side member can be rotated with respect to a driving-side member with a sufficiently small force even if inner and outer rings are connected by a frictional force applied by a connection member. Coil springs each having a pair of hook portions are mounted on the outer peripheral surface of the outer ring, which is supported by a cylindrical support member. Further, a control member for controlling the coil springs is in series in the axial direction on the support member, and the control member allows rotation about a common rotation axis of the inner and outer rings with respect to the support member. The support member and the control member are provided with hook grooves into which the hook portions of the coil springs are respectively fitted. The coil springs retain or liberate the outer ring by a required operation.
