<p>A swing hinge device of a mobile phone is provided to enable components to rotate as minimizing friction forces by using magnetic forces, thereby preventing wear caused by friction, consequently duration can be extended. Plural magnets having different magnetic forces are disposed as crossing each other on a lower casing(120). An upper casing(110) is coupled to an upper part of the lower casing. A driving plate(130) is located between the upper casing and the lower casing, and wherein plural magnets having different magnetic forces are disposed as crossing each other. A spring enables the lower casing and the driving plate to be mutually and elastically supported.</p> |
