Abstract
An exhaust gas purification device for an internal combustion engine that has a turn-back portion in an exhaust gas passageway which makes the device compact and causes a reducing agent to be evenly dispersed and flow into a reduction catalyst disposed in an exhaust gas passageway downstream of the turn-back portion. The device has a lid portion that is attached to a side surface of the body portion and the body portion has an outlet opening for the upstream-side exhaust gas passageway and an inlet opening for the downstream-side exhaust gas passageway, and the turn-back portion comprises a space enclosed by the body portion and the lid portion, and a guide portion for directing the flow direction of exhaust gas with which the reducing agent has become mixed toward the is downstream-side exhaust gas passageway is integrally molded in an opposing surface of the lid portion that opposes the inlet opening of the downstream-side exhaust gas passageway.
