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.

A conductive propylene resin composition, which is used for packaging and automatic feeding of parts which is unlikely be electrically charged, which is resistive to a baking treatment and which does not produce wastes and can reduce a material cost and a processing cost, is provided. The composition contains of (1) a % by weight of a propylene polymer with a portion having not less than 95% by weight of crystallinity that occupies not less than 60% by weight of the propylene polymer, and contains not more than 20% by weight of ethylene; (2) b % by weight of a propylene random copolymer which has a tensile elongation of not less than 100% and contains 1 to 7% by weight of ethylene; and (3) c % by weight of an electrically conductive filler, wherein the following relationships are satisfied: a+b+c=100, 0.5&#x2266;a/b&#x2266;2.0 and 10&#x2266;c&#x2266;30.
