<P>PROBLEM TO BE SOLVED: To provide a rear engine bus capable of avoiding such a situation that a supply unit for exhaust emission control is impaired by heat of an engine room. Ž<P>SOLUTION: A thermal insulation box 60 projecting inside an engine room 20 is arranged on a front wall 21 of the engine room 20. An SCR supply unit 70 is housed inside the thermal insulation box 60. The thermal insulation box 60 has a frame structure 61 fixed on the front wall 21, and a cover 62. The cover 62 prevents hot air in the engine room from entering inside the thermal insulation box 60. A side cover member 62c and a rear cover member 62e constituting a part of the cover 62 are detachable from and attachable to the frame structure 61. When the side cover member 62c and the rear cover member 62e are detached from the frame structure 61, the supply unit 70 can be inspected or subjected to maintenance through an operating opening 81. A through hole 90 is formed on a front side of the thermal insulation box 60. Inside of the thermal insulation box 60 is communicated with an instrument housing part 50 via the through hole 90.
