PROBLEM TO BE SOLVED: To quickly cope with a change of a pipe diameter, to facilitate attach ment to a lining pipe and remove from the lining pipe, and to reinforce a molded frame, in a lining work execution device for spirally winding a belt-like member formed of a long plate-like body and for constituting a lining layer on the inner surface of a pipe such as sewage piping. SOLUTION: A lining device is provided with an annular molded frame 1, guide rollers to be mounted on the periphery of the molded frame 1, and a connecting mechanism part 7 composed of an inner surface roller 5 and an outer surface roller 6, and circumference adjusting mechanisms 2 for freely adjusting the circumference are interposed in the molded frame 1. Moreover, distance holding mechanisms 3 are arranged next to the circumference adjusting mechanisms 2. |
