PROBLEM TO BE SOLVED: To provide a device for lining tube interior, which is constituted so that a lining film having uniform thickness is formed on the internal peripheral surface of the tube even in the case of using a quick setting resin. SOLUTION: This device is used for lining the tube interior by using the quick setting resin having a property of curing immediately by mixing and is provided with a spray nozzle 2, which is provided with a spray port and a chamber for mixing resins separately transported and has a ring member 2A provided on its external peripheral surface and setting the central position of its own by abutting on the internal surface of the tube to be lined, and a guide material 3, provided so as to be able to link with the spray nozzle 2 and having a wheel 5 provided on the external peripheral surface to enable to roll freely in the placing direction of the tube and in the peripheral direction. A resin transporting member 6 extending toward the spray nozzle 2 has such a structure 7 that the action of the guide material 3 is not communicated between it and the guide material.
