PURPOSE: To provide a device for supporting a radiant tube in heat treatment furnace, the device is capable of extending life of the radiant tube by mounting a rolling means between a supporting member formed on a curved surface part of the radiant tube and support member formed at the inner side of the furnace body, thereby reducing friction resistance between the supporting member and the support member. CONSTITUTION: A device for supporting a radiant tube(100) in heat treatment furnace comprises a supporting member(200) formed on a curved surface part of the radiant tube; a support member(300) projected to the inner side of the furnace body(30); and a rolling means for performing a rolling action between the radiant tube supporting member and the furnace wall support member, wherein the rolling means is a shaft part roller, simple roller or ball, wherein the device further comprises guides which are installed on both surfaces and front part of the support member, and on which a prevention projection for preventing separation of the roller is formed, wherein the shaft part roller is installed at the supporting member, and the guides are formed on the support member, wherein the shaft part roller is installed at the support member, and the guides are formed on the supporting member, and wherein the radiant tube is formed in a "W", "U" or "P" character shape.
