<p>PURPOSE:To improve durability by setting a joint plate having the intermediate thickness of the thickness of a stainless-steel plate and the thickness of a side plate between a bellows part and the side plate. CONSTITUTION:A joint plate 13 is formed by bending a stainless-steel plate having the intermediate thickness of the thickness of a stainless-steel thin plate 12a used for bellows part 12 and the thickness of a side plate 14, and said joint plate 13 is interposed between the bellows part 12 and the side plate 14. Therefore, the bellows part 12 and the side plate 14 can be connected without generating the exceedingly large deformation of the sectional surface, and an exceedingly large stress concentration is not generated in the welded part, and durability can be improved.</p> |
