Patent ID: 7614118

Claim:
A two-shaft hinge having a two-shaft structure, comprising: a rotation shaft having an axially penetrating hole through which a harness wiring can pass; an opening/closing shaft; a rotation torque unit in which a plurality of rotation torque generating portions are provided on the rotation shaft, the rotation torque generating portions being assembled by putting a first coil spring around an outer periphery of the rotation shaft and by abutting a first fixing cam and a first rotating cam on both ends of the first coil spring; and an opening/closing torque unit in which a plurality of opening/closing torque generating portions are provided on the opening/closing shaft, the opening/closing torque generating portions being assembled by putting a second coil spring around the opening/closing shaft and by abutting a second fixing cam and a second rotating cam on both ends of the second coil spring, an elongate hinge housing extending coaxially with the opening/closing shaft, wherein the rotation shaft penetrates the elongate hinge housing such that the axis of the rotation shaft and the axis of the opening/closing shaft are perpendicular to each other, the rotation shaft extending through the entire diameter of the elongate hinge housing, the elongate hinge housing having a first through-hole through which the rotation shaft pierces on one side of the rotation torque unit and a second through-hole through which the harness wiring can pass on the other side of the rotation torque unit, the torque units generate a sliding torque and a click torque at rotation, and an opening/closing operation function on the rotation shaft and the opening/closing shaft, and the opening/closing torque unit is assembled to either a right side or a left side of the rotation torque unit.
