Joining structure, method for producing joining structure, and vehicle body

Abstract

This invention provides a joining structure including a structure joining two flanges together, with which adequate anti-noise performance and anti-vibration performance can be secured even when the sheet thickness is thin. A joining structure includes a first flange, a second flange, a joint portion formed by joining the first flange and the second flange in a state in which at least one of the flanges is collapsed to the side of the other of the flanges, and a contact portion where the first flange and second flange slidably contact at a position separated from the joint portion. A gap is formed between the first flange and the second flange by the first flange, the second flange being separated a position between the joint portion and the contact portion. Energy of vibrations and noise is attenuated by the sliding of a first contact portion and a second contact portion.
