1. An exhaust purification device, comprising:
a casing which accommodates a purifier that purifies exhaust gas of an engine mounted on a vehicle, and in which a flow direction of the exhaust gas corresponds to a longitudinal direction of the casing;
an inlet opening provided at a first longitudinal end of a side face of the casing to allow the exhaust gas to flow into the casing;
an outlet opening provided at a second longitudinal end of the side face of the casing to allow the exhaust gas to flow out of the casing;
a first pipe connected to the inlet opening; and
a second pipe connected to the outlet opening, wherein
at least one of a connecting end of the first pipe for the casing and a connecting end of the second pipe for the casing extends in a lateral direction of the casing from an outside of the casing and is connected to at least one of the inlet opening and the outlet opening, and a cross section of the at least one of the connecting ends when cut along the longitudinal direction of the casing is in a flattened shape as a dimension of the cross section in the longitudinal direction of the casing is shorter than a dimension of the cross section in a lateral direction of the casing;
at least one of the connecting ends of the first pipe and the second pipe in the flattened shape extends inside the casing and is in contact with an inner surface of the casing.
