摘要：Provided is an exhaust emission control device in which only a casing for a particulate filter can be easily taken out of position with a casing for a selective reduction catalyst being left on a vehicle body in a reliably supported state. The exhaust emission control device has a particulate filter 5 and a selective reduction catalyst 6 housed in casings 7 and 8, respectively, and arranged side by side with entry ends of them are directed in one and the same direction, and an S-shaped communication passage 9 which interconnects the casings 7 and 8 and is intermediately provided with urea water addition means 10. The communication passage 9 is intermediately provided with a separable portion for suitable separate-off, and the casing 8 for the selective reduction catalyst 6 is supported by a frame 15 on a vehicle body independently of the casing 7 for the particulate filter 5. The casing 7 for the particulate filter 5 is detachably mounted and supported on the vehicle body and on the casing 8 for the selective reduction catalyst 6.
