To provide an exhaust emission control device of a vehicle which has low exhaust resistance, smoothly and readily treats exhaust, and prevents a catalyst from damaging or the like.
An exhaust emission control device of a vehicle includes: an exhaust pipe for allowing exhaust discharged from an internal combustion engine to flow; an oxidation catalyst in which unburnt components contained in the exhaust are subjected to an oxidation treatment; a particulate capturing filter provided downstream of the oxidation catalyst in the exhaust direction and for capturing particulates in the exhaust; a DPF container for housing the oxidation catalyst and the particulate capturing filter; an opening connection provided between the exhaust pipe and the DPF container and in which a cross-sectional area breaking on the vertical surface in the exhaust direction increases with the distance from the exhaust pipe to the DPF container; and a fin member provided inside the opening connection and in which a blade inclining in the exhaust direction stirs exhaust passing through the opening connection.
