<p>A working machine is provided. The working machine is capable of discharging exhaust gas from an exhaust opening while reducing heat and noise of the exhaust gas even when members are densely disposed inside an engine room and there is no space margin. An upper slewing body 4 includes a rear wall portion 12 that covers an engine room 8 from a rear side, a bottom plate 20 that is disposed so as to cover the engine room 8 from a lower side and that has an exhaust opening 27 that opens the engine room to the lower side, and a pair of vertical plates 21 and 23 that stands upright on the bottom plate 20 on both left and right sides of the exhaust opening 27 and extends in a front-rear direction on the lower side of the engine 11. A rear end portion of the vertical plate 23 has proximate rear end surfaces 23a and 51b disposed adjacent to the rear wall portion 12 and a cutout portion 50 formed by recessing the rear end surface of the vertical plate 23 toward the front side with respect to the proximate rear end surfaces 23a and 51b. A distal end portion of a tail pipe 11c is introduced between the vertical plates 21 and 23 through the cutout portion 50 from the outer position of the vertical plates 21 and 23 and extends along the exhaust opening 27 in a state where the distal end portion of the tail pipe 11c faces the exhaust opening 27.</p> |
