1A and 1B are a plan view and a side view, respectively, showing an embodiment of a hydraulic excavator according to the present invention. The hydraulic excavator is configured by installing a revolving unit 1 on a traveling unit 6 via a revolving device 7, and mounting a hydraulic power unit 8, a cab 9, and a counterweight 10 on the revolving unit 1. As shown in the figure, in this example, a small rearward turning hydraulic excavator in which the rearward projecting width of the counterweight 10 is reduced is shown. In FIG. 1A,
The hydraulic oil tank is mounted on the right side of the revolving unit 1,
