PURPOSE: A train-door device for preventing the harm due to the snow is provided to enable the opening/closing of a door to be stably performed since a heating unit is airtightly embodied to reduce the harm due to a temperature change or a flooded heating-unit and thus durability is enhanced. CONSTITUTION: A train-door device for preventing the harm due to the snow comprises a heating part(1), a first conductive part(2) and a second conductive part(3). The heating part heats the air to melt the snow from a door pocket, in which the train door is held. The first conductive part is attached to the heating part to make surface contact and transfers the heat. The second conductive part makes elastic contact with the first conductive part and transfers the transferred heat to a lower part of a door rail, on which the door slides. The heating part is fixed to the outer surface of a cover for a door pocket check, which is formed on the inner wall of a train, and is installed in the door pocket.
