ABSTRACT:
A device comprising exhaust leak preventing means made of a flexible material and mounted between a wall of a container and a catalyst element of a honeycomb structure disposed in the container to prevent leak of exhausts from an internal combustion engine mounted on a motor vehicle or the like through a gap between the container wall and the catalyst element before the exhausts are purified. Support means made of pliable metal may be used for holding the exhaust leak preventing means in place and keeping the latter from being dislodged from its position when the container is subjected to forces of impact or vibration.
