Abstract: An upper slewing body includes a rear wall portion covering an engine room from a rear side, a bottom plate disposed so as to cover the engine room from a lower side and having an exhaust opening, and a pair of vertical plates standing upright on the bottom plate. A rear end portion of the vertical plate has proximate rear end surfaces disposed adjacent to the rear wall portion and a cutout portion formed by recessing the rear end surface of the vertical plate toward the front side with respect to the proximate rear end surfaces. A distal end portion of a tail pipe is introduced between the vertical plates and through the cutout portion from the outer position of the vertical plates and extends along the exhaust opening in a state where the distal end portion of the tail pipe faces the exhaust opening.

Abstract: An operating machine comprises a machine body mounted on a lower propelling body. The machine body comprises an upper frame, and a line member mutually connecting a plurality of devices installed to the upper frame. The upper frame has a bottom plate, a pair of longitudinal plates each provided to stand on the bottom plate and extend in a front-rear direction, while being disposed in spaced-apart relation to each other in a right-left direction, and a transverse plate provided to stand on the bottom plate and extend in the right-left direction, while being joined to each of the longitudinal plates. A specific plate consisting of at least one of the pair of longitudinal plates and the transverse plate has an upper edge on which a pair of protrusions are provided in opposed relation to each other, and the line member is set to pass through between the pair of protrusions.
