Abstract

Provided is a dual-axis torque hinge capable of moving a first shaft and a second shaft one by one in order. The dual-axis torque hinge includes a plurality of stacked first friction elements (6) which engage with the first shaft (4) and a plurality of stacked second friction elements (7) which engage with the second shaft (5). Each of the first friction elements (6) has an arm (6a) wound around the first shaft (4), and is configured in a manner such that tightening torque at the time of a relative rotation of the first shaft (4) with respect to the first friction element (6) in a tightening direction is greater than loosening torque at the time of the relative rotation of the first shaft (4) with respect to the first friction element (6) in a loosening direction. Each of the second friction elements (7) has an arm (7a), and is configured in a manner such that tightening torque at the time of a relative rotation of the second shaft (5) with respect to the second friction element (7) in a tightening direction is greater than loosening torque at the time of the relative rotation of the second shaft (5) with respect to the second friction element (7) in a loosening direction. When a second main body (2) rotates in one direction relative to a first main body (1), the tightening torque acts on one of the first shaft (4) and the second shaft (5), and the loosening torque acts on the other of the first shaft (4) and the second shaft (5).
