Abstract
A dump truck includes: a main frame; an engine installed in the main frame; and an exhaust aftertreatment device that purifies exhaust gas from the engine. The main frame includes a vertical member in a portal shape which projects in a vehicle height direction of the dump truck and extends in a vehicle width direction of the dump truck. The exhaust aftertreatment device is supported by the vertical member. With this arrangement, maintenance of the engine can be conducted while the exhaust aftertreatment device is kept attached to the vertical member.
