One aspect of the present disclosure provides a muffler including an exhaust pipe and a space forming member. The exhaust pipe has a cylindrical shape having a flow passage inside through which exhaust gas passes. The space forming member forms closed spaces between itself and the exhaust pipe, the closed spaces being branched from the flow passage and adjacent to the flow passage. Each of the closed spaces and the flow passage communicate with one another via a single communication hole.

Muffler

A muffler system with a muffler in one aspect of the present disclosure includes an outer wall, and a first separator and a second separator that partition a muffling space. An attachment member is arranged on an outer surface of the outer wall, and a muffler pipe to communicate with the muffling space is arranged to pass through an attachment member hole in the attachment member. The outer surface of the outer wall includes a first area and a second area. The first area is located between a first end of the muffling space and the first separator, and the second area is located between a second end of the muffling space and the second separator. The attachment member is welded to the first and second areas of the outer surface of the outer wall.

Muffler system

A support structure for an exhaust system part that configures an exhaust system of an internal combustion engine for a vehicle includes a bracket and a support member. The bracket includes a first plate and a second plate. The first plate has both end portions attached to the second plate, and the second plate has both end portions attached to the exhaust system part. A first space is defined between the first plate and the second plate, and a second space is defined between the second plate and the exhaust system part. Each of the first space and the second space has a first open end disposed on the vehicle front side, and has a second open end disposed on the vehicle rear side. The first plate, the first space, the second plate, and the second space are disposed between the support member and the exhaust system part.

Support structure for exhaust system part

In an exhaust system of an internal combustion engine, an exhaust pipe is reliably bent and deformed during vehicle rear collision while improving drainage performance in the exhaust pipe in normal times. The exhaust systemincludes a second pipecorresponding to a downstream end part of an exhaust pipethrough which exhaust gas flows from an engine. The second pipeincludes: a fragile partas a starting point of bending deformation of a tail pipe; and a partition platevertically dividing the inside of the second pipeto form, under the partition plate, a lower passageto flow water that accumulates in the exhaust pipe. The partition plateis in a vicinity of the fragile partand at a position not overlapping with the fragile partin an axial direction of the second pipe
