Abstract
The disclosure relates to a catalytic converter for cleaning exhaust gas generated from automobiles or the like and more particularly to a structure for securing a catalyst carrier to a casing. In the converter, a casing for embracing, supporting and securing the catalyst carrier is provided with at least one end cover at the one end of the casing in the longitudinal direction thereof, the catalyst carrier is secured to the one end cover, but not secured to the remainder of the casing. The catalyst carrier may be secured to the end cover by sandwiching the flange portion of the catalyst carrier between the vertical step portion of the end cover and a pushing ring via buffering members. Alternatively, the catalyst carrier may be secured to the end cover by pushing a taper bushing having a wedge-shaped cross section into the space between the concave recessed portion provided on the surface of the catalyst carrier and the short pipe portion of the end cover. Mesh washers formed from a knitted metal wire mesh can be used for the buffering members.
