Abstract

Provided is an exhaust apparatus for a vehicle, being capable of performing a normal detection of a nitrogen oxide (NOx) concentration in exhaust gas without involving increase in the size and the cost. The exhaust apparatus includes an exhaust pipe having an upstream end connected to an aftertreatment device and a downstream end enclosing an exhaust port at a position higher than the upstream end, a NOx sensor to be retained in the exhaust pipe, and a water barrier wall provided inside the exhaust pipe. The water barrier wall has a shape to form a shield between the NOx sensor and the exhaust port while leaving a gas inlet that allows the exhaust gas to flow to the NOx sensor from the aftertreatment device through the gas inlet.
