FIELD: railway and road vehicles. SUBSTANCE: gear to handle movable door has pantograph to move door fold in its lateral plane, supporting-guiding beam and guiding rod with carriage mounted on rod for longitudinal movement. Beam and rod are installed in direction of displacement of fold one parallel another and are fixed immobile relative to door frame. Pantograph is put on carriage, mounted on two hinges and is fitted with at least two hinges for attachment to fold and its fixing in extended position by means of coupling. Roller that bears against beam to create moment equalizing moment of gravitational force of fold in its vertical lateral plane is anchored on carriage. EFFECT: simplified design of gear and its operational reliability. 3 cl, 4 dwg
