Abstract
Disclosed is an exhaust purification device in which an entire length of an outer cylinder of a catalyst can be used effectively for exhaust purification and it is possible to prevent heat in fixing of the catalyst to an exhaust pipe from affecting a connection portion between the outer cylinder and catalyst main bodies. A catalyst includes an outer cylinder and a plurality of catalyst main bodies provided in the outer cylinder in a state of being spaced each other in a direction of an axial center of the outer cylinder. An outer face of the outer cylinder positioned between the catalyst main bodies is a fixed face to be fixed to an inside of the exhaust pipe.
