<p>PROBLEM TO BE SOLVED: To manufacture a repair device for repairing the damaged portion of an exhaust tube at a low cost, and to increase the flexibility thereof. SOLUTION: A main sheet part 20 and auxiliary sheet parts 40 are formed in one rectangular sheet metal 10. The main sheet part 20 comprises a slender piece group 22A. The auxiliary sheet parts 40 are tightened to the exhaust tube with band-like tightening devices. The sheet metal 10 can be cut out any portions to eliminate unnecessary parts, and used by winding on the exhaust tube at various damaged portions such as the straight portion, branched portions of the exhaust tube, and the surface plate part of an exhaust box. As necessary, putty is mounted at the damaged portions, and the putty is held by the slender piece group 22A.</p> |
