<P>PROBLEM TO BE SOLVED: To provide an inexpensive reformer whose joined parts can be made to be precisely airtight and furthermore can be automatically joined without welding strain. <P>SOLUTION: The reformer has the joined parts everywhere at which a tubular part and a plate part are airtightly joined. All of the joined parts or a specific joined part are formed by bending a cylindrical edge of the tubular part and the joined edge of the plate part at least whose joined edge is overlapped to the cylindrical edge to an inner circumferential face side or to an outer circumferential face side of the plate part while they are overlapped. <P>COPYRIGHT: (C)2003,JPO |
