摘要： An object is to provide an exhaust gas purification device configured so that a precipitated reducing agent is less likely to be attached to a mixer. An exhaust gas purification device (1) includes: a spray nozzle provided in an exhaust pipe of an engine; a mixer (11) provided downstream of the spray nozzle in a flow direction of exhaust gas; and a catalyst reactor provided downstream of the mixer (11), the exhaust gas purification device being configured to spray a reducing agent from the urea water spray nozzle (2) to the exhaust gas from the engine (18), to mix the reducing agent with the exhaust gas in the mixer (11), and to reduce one or more nitrogen oxides in the exhaust gas using a catalyst contained in the catalyst reactor (12). The mixer (11) includes: a cylindrical body (21); and a plurality of fins (22) arranged in the cylindrical body (21) radially outward with respect to an axis of the cylindrical body (21), and an upstream portion of each fin (22) is shaped to provide a cutoff portion (221) formed by cutting the fin (22) from an upstream side end portion (22a) of the fin (22) toward the axis and toward a downstream side of the fin (22).
