Beschreibung
Zusammenfassung:	A reducing agent supply device for supplying a reducing agent on the upstream-side of SCR catalyst in an exhaust gas flow channel, said reducing agent supply device being provided with: at least one header pipe, which extends inside the flow channel and is configured so that the reducing agent can flow through the interior thereof; multiple jetting nozzles, which are provided in the header pipe separated along the direction in which the header pipe extends and are configured so as to be able to jet the reducing agent into the flow channel; a heat-shielding plate, which is provided on the upstream side of the header pipe in the exhaust gas flow direction and the longitudinal direction of which runs parallel to the direction in which the header pipe extends; and at least one fixing part, which contacts each of the heat-shielding plate and the header pipe and fixes the heat-shielding plate to the header pipe. The at least one fixing part is provided at at least one site in the direction in which the header pipe extends.
