An exhaust gas processing device includes: a manifold configured to change a travelling direction of exhaust gas from a first direction to a second direction; a first catalyst carrier into which the exhaust gas that has been guided from the manifold flows, the first catalyst carrier being configured to purify the exhaust gas that is flowing in the second direction; a heater provided on the upstream of the first catalyst carrier in the flowing direction of the exhaust gas, the heater being configured to heat the exhaust gas that has entered from the manifold; and a case accommodating the first catalyst carrier and the heater, wherein an inlet-side opening portion of the case is inserted into the manifold to a position facing an inlet of the manifold, and the inlet-side opening portion is formed with an inlet-side cut-out portion configured to allow passage of the exhaust gas.

Exhaust gas processing device

A turbine housing includes an inner pipe and an outer pipe, the inner pipe being configured to form an exhaust air flow path between an exhaust-air-inlet-side flange and an exhaust-air-outlet-side flange, and an outer pipe being configured to cover the inner pipe such that a predetermined spacing is formed between the inner pipe and the outer pipe. The inner pipe has: an inner pipe main body configured to form the exhaust air flow path having a spiral shape, the inner pipe main body being connected to the exhaust-air-inlet-side flange such that exhaust gas is allowed to enter between the inner pipe and the outer pipe; and an exhaust tube attached to an exhaust air outlet side of the inner pipe main body in a freely slidable manner with an intervening sealing member.
