Abstract
A hydraulic excavator (1) includes a wireless authentication starting device (37) for switching conduction or non-conduction between a battery (18) and a starter motor (16) as well as a first electrical component (24) on the basis of an operation of a power switch (12) provided in the vicinity of an operator's seat (9) and authentication of a portable key (38) by wireless communication. The wireless authentication starting device (37) switches an “engine stop/conduction OFF” state to an “engine stop/conduction ON” state when, in the “engine stop/conduction OFF” state, the portable key (38) is within an authenticable range, the gate lock lever (13) is at an unlock position, and the power switch (12) is operated.
