EXHAUST SYSTEM SUPPORT STRUCTURE

PROBLEM TO BE SOLVED: To provide an exhaust system support structure capable of improving strength with a simple structure.SOLUTION: An exhaust system support structure 1 includes: a tubular exhaust system member 2; a seat plate 3 disposed along an outer peripheral surface 21 of the exhaust system member 2; and a rod-like stay 4 for supporting the exhaust system member 2. In the seat plate 3, the outer peripheral end edge is welded to the outer peripheral surface 21 of the exhaust system member 2. The stay 4 includes an erected end 41 erected from the seat plate 3, and the erected end 41 is welded to the seat plate 3. In a cross section including a central axis 410 of the erected end 41 of the stay 4, a first weld section 51 to be a weld section of the seat plate 3 and the exhaust system member 2 is located outside a second weld section 52 to be a weld section of the stay 4 and the seat plate 3. 【課題】簡易的な構造で強度向上が可能な排気系支持構造を提供すること。【解決手段】排気系支持構造１は、管状の排気系部材２と、排気系部材２の外周面２１に沿って配設される座板３と、排気系部材２を支持する棒状のステー４とを備えている。座板３は、その外周端縁部が排気系部材２の外周面２１に溶接されている。ステー４は、座板３から立設された立設端部４１を有し、かつ、立設端部４１が座板３に溶接されている。ステー４の立設端部４１の中心軸４１０を含む断面において、座板３と排気系部材２との溶接部分である第１溶接部５１は、ステー４と座板３との溶接部分である第２溶接部５２よりも外側にある。【選択図】図２
