Abstract
A hydraulic excavator is provided, facilitating access to the lower side inside an engine compartment, allowing a maintenance job to be performed in a reasonable posture.

A recess indented from the bottom face in the upward direction is formed at the counterweight. An opening is formed at the revolving frame for allowing a person to access from the lower side of the revolving frame to the space between the engine and the counterweight. The recess has a section overlapping with the opening, when viewed from the top.
