CONSTRUCTION MACHINE

The present invention comprises: a hydraulic pump (4); an actuator; cutoff levers (135L, 135R) that disable the actuator; a speed adjustment lever (31) for an engine governor; a return spring (32) that urges the speed adjustment lever (31) to a low-speed rotation side (L); a control cable (5) that can pull the speed adjustment lever (31) to a high-speed rotation side (H); an accelerator lever (136) that can be operated so as to actuate the control cable (5) in a pulling direction (T) and a release direction (R); and a relay device (6) provided partway on the control cable (5), the relay device (6) having a pulling force release mechanism that turns the cutoff levers (135L, 135R) when the accelerator lever (136) is operated in the pulling direction (T), and releases the pulling force of the control cable (5) on the speed adjustment lever (31) in coordination with the state in which the actuator is disabled.
