The invention discloses a stay-rope fixing device for an arm rest. The stay-rope fixing device comprises a head-part lifting arm rest and two central shafts, wherein the two central shafts are symmetrically arranged at the two sides of the head-part lifting arm rest; the tail ends of the outer sides of the two central shafts are respectively provided with a fixed plate; the two central shafts are respectively provided with a supporting beam in a sheathing manner; the two ends of each supporting beam are symmetrically provided with stay-rope pin shafts; ring-shaped sleeves are respectively arranged on the stay-rope pin shafts in a sheathing manner; the excircles of the ring-shaped sleeves are respectively provided with a circle of groove; and inclined stay ropes are arranged in the grooves in a surrounding manner. By the mode, the stay-rope fixing device disclosed by the invention has the advantages that four groups of inclined stay ropes are adopted for lifting, so that the strength is high; the supporting beams which can rotate are specially designed, so that the anti-vibration performance and the use stability are improved; and the manufacture is simple, the cost is low and the reliability is high.
