Beschreibung
Zusammenfassung:	An exhaust gas treatment device (1) of the present invention is configured such that a catalyst unit (40) for treating exhaust gas is held in a vessel body (10) forming a gas passage (R) of a flow of the exhaust gas. The exhaust gas treatment device (1) includes a downstream-side grid (30) provided downstream of the catalyst unit (40) along the gas passage (R), an upstream-side grid (70) provided on the opposite side of the catalyst unit (40) from the downstream-side grid (30), a retainer (80) that presses the catalyst unit (40) between the upstream-side grid (70) and the downstream-side grid (30), and an elastic seal member (32) interposed between the downstream-side grid (30) and the catalyst unit (40). The elastic seal member (32) is elastically deformed by pressing the catalyst unit (40) with the retainer (80) and seals a gap between the downstream-side grid (30) and the catalyst unit (40).
