Abstract:
1. A holding seal member for winding around an exhaust gas purifier body that has an inlet end face into which exhaust gas enters and an outlet end from which the exhaust gas exits, and holding the exhaust gas purifier body in a tubular shell, the holding seal member comprising: a first surface for contacting the exhaust gas purifier body during use of the holding seal member; a second surface for contacting the shell when the holding seal member is wound around the exhaust gas purifier body; and an inlet-side chamfered end placed adjacent the inlet end face of the exhaust gas purifier body during use of the holding seal member, wherein the inlet-side chamfered end includes an inclined surface inclined relative to at least the second surface when the holding seal member is in a not deformed state before pressing the holding seal member and the exhaust gas purifier body into the tubular shell, wherein at the inlet-side chamfered end in the not deformed state the first surface has a terminal end and the second surface has a terminal end adjacent the inclined surface and that terminates short of the terminal end of the first surface; wherein the inlet-side chamfered end does not project from the inlet end face of the exhaust gas purifier body toward an exhaust gas inlet of the tubular shell when the holding seal member is in a deformed state as received in the tubular shell with the holding seal member deformed by shearing forces acting on the first and second surfaces in contact with the exhaust gas purifier body and tubular shell respectively when the holding seal member and the exhaust gas purifier body are pressed into the tubular shell.
