Patent attributes
An exhaust device for a multi-cylinder engine for connecting both exhaust passage members with a communicating hole formed in each one when the two exhaust passage members are to be spaced apart. A base plate has a through hole communicating with the communicating hole and a cover plate for covering the outside of the base plate. The outer circumferential area of the through hole of the base plate overlaps the outer surface of the exhaust pipe with the entire outer circumferential area of the through hole is welded to the exhaust pipe. The edge portions on both sides of the cover plate are welded to the base plate so as to surround the outer side of the through hole. The area extending between edge portions on both sides of the cover plate is welded to the front and rear edge portions of the base plate.
