PURPOSE: A hinge structure of a flat-panel image display device is provided to make a work convenient by taking a rotation axis as a simple circular axis, and to easily adjust the friction and the braking force added according to the weight of the flat-panel image display device. CONSTITUTION: The rotation axis(5) makes rotation plates(10a,10b) rotate by inserting into a perpendicular surface of the rotation plates(10a,10b) and a fixed plate(20). A friction tool(41) grips the rotation axis(5) by forming on the circumference of the rotation axis(5), and forms a planar friction tool tightening surface having the second insertion hole(41h) at both ends. A tightening part(70) tightens the friction tool tightening surface by inserting into the second insertion hole(41h), and causes the strong braking force by tightening the rotation axis(5) with the friction tool(41). |
