<p>Provided is an exhaust emission purifying device having a sensor disposed at a portion where no erroneous detection of data occurs. The exhaust emission purifying device comprises a casing for enveloping a catalyst carrier, a mixing pipe, a dispersion chamber for guiding the exhaust gas flowing in the mixing pipe to the exhaust inlet end of the casing, and a sensor. Of the region of 360 degrees, as viewed from the exhaust inlet end of the casing, on the casing axis, the region, which is normal to an exhaust flow center line joining the mixing pipe axis and the former axis and which is contained in the range on the opposite side of the mixing pipe with respect to a boundary line extending in the radial direction of the casing while intersecting that former axis, is set to a portion for mounting the sensor in the casing.</p> |
