Abstract
Provided is a method for manufacturing an automotive exhaust component. The method includes joining first and second members included in an insulator. The first member includes: a first main body; a first joining portion located at an end of the first main body; and a first positioner provided to the first joining portion. The second member includes: a second main body; a second joining portion located at an end of the second main body; and two second positioners provided to the second joining portion. Once the first and second members are in position, the first joining portion faces the second joining portion, and the first positioner is situated between the two second positioners. The first and second joining portions are swaged with each other thereafter.

A method for manufacturing an automotive exhaust component, the method comprising:
- arranging first and second members so as to be located on both sides of a flow path member, the first and second members each having a plate shape and being included in an insulator that surrounds the flow path member, the flow path member extending along an axial line and being provided with a path for exhaust gas therein;
- and
- joining the first and second members,
- wherein the first member includes:
- a first main body that is arranged to face an outer-circumferential surface of the flow path member;
- a first joining portion having a flange shape that is provided at an end of the first main body in a circumferential direction about the axial line;
- and
- a first positioner provided to the first joining portion,
- wherein the second member includes:
- a second main body that is arranged to face the outer-circumferential surface of the flow path member;
- a second joining portion having a flange shape that is provided at an end of the second main body in the circumferential direction;
- and
- two second positioners that are provided to the second joining portion and aligned in a direction of the axial line,
- wherein, once the first and second members are in position, the first joining portion faces the second joining portion, and the first positioner is situated between the two second positioners,
- wherein the first and second joining portions are swaged with each other, and the first and second members are thus joined, and
- wherein the first positioner is provided at an end of the first joining portion opposite to the first main body and has a plate shape protruding toward the second joining portion.
