Abstract

To restrain generation of a sound from a heat shielding cover for covering a part of an exhaust pipe, in an exhaust system of a vehicular engine for connecting the upstream end of the exhaust pipe to a cylinder head of the engine mounted on a vehicle, and connecting an exhaust muffler to the downstream end of the exhaust pipe. A stay 25 having a support plate part 25b curved so as to cover a part of the outer periphery of the exhaust pipe 17 from the outside, is fixed to the heat shielding cover 22 for covering a part near at least the engine of the exhaust pipe 17. The support plate part 25b for sandwiching a vibration control member 26 between the part and the outer periphery of the exhaust pipe 17, is installed in the exhaust pipe 17 by fastening of a band member 29 for sandwiching a vibration control member 27 between the member and the support plate part 25b.

Description

technical field [0001] The present invention relates to an exhaust device for a vehicle engine. The upstream end of an exhaust pipe is connected to a cylinder head of an engine mounted on a vehicle, and an exhaust muffler is connected to a downstream end of the exhaust pipe. Background technique [0002] Such an exhaust device is disclosed in, for example, Patent Document 1 or the like. [0003] [Patent Document 1] JP-A-2001-123829 [0004] Such an exhaust device vibrates due to the exhaust pressure. As disclosed in the above-mentioned Patent Document 1, when the heat shield covering the exhaust pipe is directly attached to the exhaust pipe with a band, The vibrations will propagate to the heat shield, and the sound generated by the vibration of the heat shield may become louder. Contents of the invention [0005] The present invention has been made in view of such circumstances, and its first object is to provide an exhaust system for a vehicle engine capable of suppres...
