Claims5
An exhaust system comprising:
- an exhaust pipe including a straight portion, and a bent portion that is bent and extends from a downstream end of the straight portion;
- a muffler provided on a downstream side of the exhaust pipe;
- and
- a vibration reducing reinforcing member for reducing vibration of the exhaust system, wherein:
- the straight portion of the exhaust pipe is connected with an upstream end portion of the muffler through the bent portion;
- the vibration reducing reinforcing member is provided such that one end of the vibration reducing reinforcing member is directly connected to an outer surface of the exhaust pipe at a downstream end portion of the straight portion, and an opposite end of the vibration reducing reinforcing member is connected to a surface of the upstream end portion of the muffler;
- the vibration reducing reinforcing member comprises a plate having a shape that is wider at the end of the vibration reducing reinforcing member connected to the surface of the upstream end portion of the muffler and tapered toward the end of the vibration reducing reinforcing member directly connected to the outer surface of the exhaust pipe;
- and
- the vibration reducing reinforcing member includes both
- a projecting bead having an approximately C-shaped section that projects in a direction separating from the bent portion, projects outside a circumference of the muffler at least at the end connected to a surface of the upstream end portion of the muffler, and extends in a direction extending across the straight portion and the muffler, and
- a flange portion along only one tapered side edge portion of the plate, the flange being bent in a direction separating from the bent portion and extending along the direction extending across the straight portion and the muffler.
