Document Type and Number:
Japanese Patent JP7288211
Kind Code:
B2
Abstract:
This invention provides a joining structure that includes a structure that joins two flanges together, and with which adequate anti-noise performance and anti-vibration performance can be secured even when the sheet thickness is made thin. A joining structure 30 includes a first flange 13, a second flange 23, a joint portion 32 formed by joining the first flange 13 and the second flange 23 in a state in which at least one of the flanges 13 and 23 is collapsed to the side of the other of the flanges 13 and 23, and a contact portion 33 where the first flange 13 and the second flange 23 slidably contact at a position that is separated from the joint portion 32. A gap 34 is formed between the first flange 13 and the second flange 23 by the first flange 13 and the second flange 23 being separated from each other at a position between the joint portion 32 and the contact portion 33. Energy of vibrations and noise is attenuated by the sliding of a first contact portion 45 and a second contact portion 55 of the contact portion 33.
