PROBLEM TO BE SOLVED: To provide a roller conveyor can contribute to space saving with a simple structure, and effectively secure the rotation of bearings without electric power. SOLUTION: The roller conveyor includes roller bodies 12 conveying a transferred article to an adjacent rooms by letting it through openings formed on partition walls of a plurality of rooms that differ in temperature, and a heat pipe 18 arranged in the vicinity of a bearing part 15 rotating the roller bodies 12, and also piped from a room to a room with high temperatures among the plurality of rooms that differ in temperature. A heat absorption part 18a located in the side of the rooms with high temperatures among the plurality of rooms that differ in temperature, and a heat dissipation part 18b located in the side of the rooms with low temperatures among the plurality of rooms that differ in temperature are integrally formed in the heat pipe 18.
