Abstract

A hinge device of a mobile communication terminal is provided to configure a damping ring and oil for generating frictional resistance inside a hinge so that a folder or a flip of the terminal can be smoothly opened, thereby improving an opening/closing action. A hinge housing(100) consists of a cam receiver(110) and a hinge shaft insertion hole(120). A hinge shaft(200) is inserted into the insertion hole(120), and has the first fixed pin insertion unit(210) on one side. A hinge cam(300) is inserted into the cam receiver(110) as being mounted at the end of the hinge shaft(200), and is rotatable by being equipped with the second fixed pin insertion unit(340) and a frictional resistance unit(320). A sliding cam(400) interacts with the hinge cam(300), and reciprocates in the cam receiver(110). An elastic member(500) applies an elastic force in order to be compressed or elongated by reciprocating motion of the sliding cam(400). A frictional member generates frictional resistance by being installed in the frictional resistance unit(320) of the hinge cam(300).
