ABSTRACT:
Two-shaft hinge mechanism components enabling harness wiring are provided to realize durability, reduction in size and weight and a mechanism to restrict rotation, in cellular phones, notebook computers and remote controllers required to have a smaller size, less weight and new functions. Rotation shaft and opening/closing shaft are inserted into coil spring, concave and convex cams, and a caulking component, to assemble a rotation shaft torque unit and an opening/closing torque unit. The units are attached to a hinge housing to constitute the two-shaft hinge. The opening/closing torque unit is disposed either on the left or right side of the hinge housing. A pipe-like shaft with a hollow is employed as rotation shaft, whereby harness wiring is provided easily. The torque unit is configured independently from the rotation shaft and the opening/closing shaft to achieve generation of a stable torque and click, improvement of durability, easy assembly of the components, reduction of size and weight by reducing the number of components, and ensuring of space by disposing the components in a concentrated manner.
