Hinge and foldable electronic device using the hinge

A foldable electronic device comprising:

• a main housing enclosing parts of said foldable electronic device;
• a cover enclosing other parts of said foldable electronic device and disposed next to said housing so as to be rotatably movable relative to said housing between a first position where a side of said housing is covered by said cover, and a second position where said side of said housing is revealed from said cover;
• and
• a hinge mechanism interconnecting said housing with said cover so as to allow movement of said cover relative to said housing between said first position and said second position thereof, said hinge mechanism comprising a central part engagably movable together with one of said housing and said cover and a peripheral part engagably movable together with the other of said housing and said cover, said peripheral part formed surrounding said central part and movably engagable with said central part, and engagement of said peripheral part and said central part enabling rotational movement and axial movement of said peripheral part along said central part so as to guide said movement of said cover.
