Abstract
An exhaust purification device for purifying exhaust gas flowing in an exhaust gas flow passage of an engine includes: a cylindrical casing; a pipe that is disposed on a downstream side of the casing and inserted in the casing so as to extend in a direction substantially orthogonal to an axial direction of the casing, the pipe being provided with a through-hole communicating with the casing; and an injector configured to inject a reducing agent from an upstream end of the pipe into the pipe, in which a contracting flow passage portion narrowing in an axial direction of the pipe from an upstream side toward the downstream side is formed in the exhaust gas flow passage in the casing.
