PROBLEM TO BE SOLVED: To provide an exhaust purification device for an internal combustion engine capable of improving mountability on a vehicle and improving a NOx purification rate. SOLUTION: A first housing (18) that houses a front-stage catalyst (28) and a particulate filter (32), and a second casing that houses a selective reduction-type NOx catalyst (42) and a rear-stage catalyst (46). The housing (20) is extended in the width direction of the vehicle, connects the first housing and the second housing, and connects the first housing and the second housing to the vehicle. And a connecting pipe (19) disposed across the frame (6). [Selection] Figure 2 |
