ABSTRACT:
A biaxial hinge having a rotating mechanism that realizes durability, a good tactile feedback, smaller size and more lightweight is provided for use in a notebook computer or a portable telephone that needs to be smaller and more lightweight. The biaxial hinge is constituted such that a rotating shaft support member is fixed to a rotational shaft support member, a rotation-side member is inserted and attached to the outer periphery of the rotating shaft member, and an opening/closing torque unit mechanism for opening and closing operations is disposed at the rotation-side member, wherein sliding friction torque and click torque are generated by the load produced by a coil spring between pressing members and the rotating shaft support member or a sliding member attached to the rotating shaft member. The rotating mechanism of the biaxial hinge of the present invention affords good durability, a good tactile feedback, and a reduction in size and weight. And, this rotating mechanism is applied to a portable telephone.
