Claims

[Scope of utility model registration request]

In a catalytic converter device in which a catalyst support is housed in a catalyst container via a heat insulating member that covers the outer circumferential surface of the catalyst support, an outer cylinder constituting the outer circumference of the catalyst support is connected to the outer circumference of the front and rear ends. Each of the protrusions is formed in a shape having a protrusion continuous in a ring shape in the circumferential direction, and the opposing inner end surfaces of the protrusion are formed into tapered surfaces whose height changes from low to high as they go outward, The catalyst container is provided with a tapered surface portion that slopes along the tapered surface of the protrusion, and the clearance between both tapered surfaces in which the heat insulating member is interposed is determined by the heat insulating member between the intermediate portions of the catalyst container and the outer cylinder. A catalytic converter device characterized in that the clearance is set smaller than the intervening clearance, and the catalyst support is held mainly by the tapered surface of the projection.
