The present invention relates to an exhaust purification device in which a honeycomb core body is formed by winding the honeycomb core body, and a catalyst material for exhaust purification is coated on the surface of the honeycomb core body.

る。[Prior Art] Generally, a catalytic exhaust gas purification device for an automobile has a structure in which a core body is provided within an outer cylinder, and a catalytic substance is coated on the surface of the core body. Various types of core bodies have been developed so that the core body has a large contact area with the exhaust gas and does not create resistance to the flow of the exhaust gas. As this core body, there is a so-called honeycomb core body in which stainless steel foil or the like is formed into a corrugated shape, and this is overlapped with a flat stainless steel foil and wound into a cylindrical shape. Since this type uses thin metal foil, it has features such as low resistance to the flow of exhaust gas.

浄化効率が低下する不具合があった。By the way, since such a honeycomb core body has the winding end edges of the corrugated foil and the flat foil on its curved surface, a step with a height corresponding to the thickness of these is formed. Therefore, when such a honeycomb core body is inserted into a cylindrical outer cylinder, a gap is formed near this step. Therefore, the exhaust gas flows through this gap, and the exhaust gas passing through this gap does not come into sufficient contact with the catalyst substance, resulting in a problem that the exhaust gas purification efficiency decreases.

An object of the present invention is to provide an exhaust gas purification device that can improve the purification efficiency of exhaust gas without forming a gaseous substance.
