Patent ID: 7713494

Claim:
An exhaust purification device, comprising: an exhaust pipe; a catalyst disposed inside the exhaust pipe, the catalyst including (i) an outer cylinder, and (ii) a plurality of catalyst main bodies disposed inside the outer cylinder and directly attached to the outer cylinder, the plurality of catalyst main bodies including a first catalyst main body and a second catalyst main body; and a mounting bracket connecting the exhaust pipe to the outer cylinder, wherein the second catalyst main body is spaced apart from the first catalyst main body in an axial direction of the outer cylinder such that a mixing space is provided between the first catalyst main body and the second catalyst main body, wherein the catalyst is configured to allow an exhaust gas to flow therethrough in an exhaust gas flow direction, wherein a fixing portion of the outer cylinder is disposed directly radially outwardly of the mixing space in a radial direction of the outer cylinder, the fixing portion being a portion of the outer cylinder, and the radial direction of the outer cylinder being perpendicular to the exhaust gas flow direction, and wherein the mounting bracket is welded to the outer cylinder at the fixing portion such that a welded junction of the mounting bracket and the outer cylinder is directly above the mixing space in the radial direction of the outer cylinder.
