Working machine
First Claim
1. A working machine comprising:
- a lower traveling body; and
an upper slewing body provided on the lower traveling body so as to be able to slew and the upper slewing body being configured to perform a working operation according to an operation of an operator, wherein the upper slewing body includes;
an engine provided in a rear portion of the upper slewing body;
an exhaust pipe having a base end portion connected to the engine and a distal end portion for discharging exhaust gas, the exhaust pipe extending from the base end portion to the distal end portion in order to guide exhaust gas;
a rear wall portion covering an engine room accommodating the engine from a rear side;
a floor wall portion disposed so as to cover the engine room from a lower side and the floor wall portion having an exhaust opening that opens the engine room to a lower side; and
a pair of vertical plates standing upright on the floor wall portion and the pair of vertical plates extending in a front-rear direction on a lower side of the engine, the exhaust opening being formed in the floor wall portion at an inner position between the pair of vertical plates, whereinone of the pair of vertical plates is a pipe-insertion vertical plate, and the pipe-insertion vertical plate includes a rear end portion having a proximate rear end surface disposed adjacent to the rear wall portion so as to prevent the exhaust pipe from passing between the pipe-insertion vertical plate and the rear wall portion and a cutout portion formed by recessing a rear end surface of the pipe-insertion vertical plate toward a front side with respect to the proximate rear end surface,the exhaust pipe has an outer portion between the base end portion and the distal end portion and an extending portion between the outer portion and the distal end portion, the outer portion of the exhaust pipe lying at an outer position of the pair of vertical plates, the extending potion of the exhaust pipe extending through the cutout portion, andthe distal end portion of the exhaust pipe is disposed at the inner position between the pair of vertical plates, and the distal end portion of the exhaust pipe extends along the exhaust opening in a state of facing the exhaust opening.

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.
