Disclosed is a hinge assembly for an automobile armrest for reducing or preventing noise during the opening/closing of the armrest and providing smooth opening/closing force using a damping force of gears. In the hinge assembly, a first body includes a first mounting plate, a pair of first rotating members, and a first fixed gear. A second body includes a second mounting plate, a pair of second rotating members, and a second fixed gear. Hinge shaft is coaxially aligned to the first and second fixed gears at lower ends of the first rotating member of the first body and the second rotating member of the second body. A pair of springs is wound around both outer surfaces of the hinge shaft and provides a resilient force to the first and second bodies. A support plate is mounted at a rear space of a second stage tray.
