Patent ID: 8348013

Claim:
An exhaust device of an internal combustion engine, the exhaust device being adapted to discharge exhaust gas of the engine through an exhaust pipe, comprising: a sound-deadening and pressure-dissipating device connected to a downstream end of the exhaust pipe; wherein the sound-deadening and pressure-dissipating device includes a spherical member having an opening portion opening toward a downstream edge of the exhaust pipe, and exhaust gas from the exhaust pipe is reflected by an inner spherical surface of the spherical member to reduce exhaust pressure in the spherical member and then the exhaust gas is discharged from the opening portion, wherein the sound-deadening and pressure-dissipating device includes: a housing for housing the spherical member, and a support portion with three leg portions extending radially between the housing and the spherical member, so that the spherical member is supported inside the housing in a position that is spaced apart from inner walls of the housing, wherein the housing includes: a first housing section attached to the downstream end of the exhaust pipe, a third housing section having a cylindrical shape attached to the downstream end of the first housing section, and a second housing section having a cylindrical shape attached to the downstream end of the third housing section, and the spherical member is positioned in a manner such that the opening portion of the spherical member is disposed upstream of the cylindrical third housing section.
