Abstract
A work machine includes an operating device operable in a first direction and a second direction, a hydraulic pump configured to supply hydraulic oil, a hydraulic actuator, a directional control valve configured to control the hydraulic oil flowing from the hydraulic pump to the hydraulic actuator, and a hardware processor configured to control the directional control valve based on the amount of operation of the operating device. The operating device is structured or placed such that a force is likely to escape in the first direction when the operating device is operated in the second direction. The operating device is configured such that a dead area increases with respect to the first direction in which the force is likely to escape.
