Abstract:
1. A construction machine comprising: a lower travelling body; an upper slewing body mounted on the lower travelling body so as to be slewable, the upper slewing body including an upper frame including a bottom plate and a floor plate provided above the bottom plate at a vertical interval, a seat stand provided rearward of the floor plate and on the upper frame and defining an under-seat space between the seat stand and the bottom plate of the upper frame, an operator's seat provided on the seat stand, and a partition wall provided in a front portion of the under-seat space to define a front space at a front side of the partition wall; an electric-component box installed in the front space and accommodating an electric component; a maintenance-requirement device requiring maintenance therefor and installed in a space which is included in the under-seat space and located at a rear side of the front space; and a harness for connecting the electric component in the electric-component box to an external device located outside the under-seat space, wherein: the seat stand includes a front wall located forward of the front space, the front wall including a front opening which brings an outer space forward of the front wall and the front space rearward of the front wall into communication with each other; the partition wall includes a rear opening which brings the front space forward of the partition wall and the under-seat space rearward of the partition wall into communication with each other; the seat stand includes a wiring port for introducing the harness into the front space through the wiring port; the harness includes a region to be routed in the front space, the region including a downward-extending portion extending downward from a position having a height equivalent to a height of the wiring port to a lower portion of the front space and an upward-extending portion extending upward from a first height position having a height equivalent to a height of a lower end of the downward-extending portion to a second height position which allows the harness to be connected to the electric component, the region thus routed in a devious path having a routing length larger than a length of the shortest path from the wiring port to the electric component, the routing length including allowance enough to allow the electric-component box to be removed, while remaining connected to the harness, between a first position where the electric-component box closes the rear opening at a front side of the rear opening and a second position where the electric-component box allows maintenance work for the maintenance-requirement device to be performed through the front opening and the rear opening, wherein:
