Exhaust Gas Processing Device

An exhaust gas processing device configured to process exhaust gas discharged from an engine, the exhaust gas processing device comprising:

• a manifold having an inlet through which the exhaust gas that has been discharged from the engine and that is flowing in a first direction enters and an outlet configured to guide the exhaust gas to downstream such that the exhaust gas flows in a second direction intersecting with the first direction, the manifold being configured to change a travelling direction of the exhaust gas from the first direction to the second direction;
• a first catalyst carrier into which the exhaust gas that has been guided from the outlet of 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 upstream of the first catalyst carrier in a flowing direction of the exhaust gas, the heater being configured to heat the exhaust gas that has entered from the manifold and that is to be guided to the first catalyst carrier;
• and
• a case accommodating the first catalyst carrier and the heater, wherein
• an inlet-side opening portion of the case is inserted into an inner circumference of the outlet of the manifold to a position facing the inlet of the manifold, and
• the inlet-side opening portion is formed with an inlet-side cut-out portion, the inlet-side cut-out portion being configured to allow passage of the exhaust gas flowing from the inlet of the manifold.
