    摘要： A mechanism for prioritizing a handle operation is achieved with a simple configuration and the mechanism is actuated in a stable manner in a wheel loader in which steering can be operated by a handle operation and a lever operation. The steering device includes a handle (21), a joystick (22), steering cylinders (23L, 23R), a steering valve (25), a pump (30), an orbit roll (26) for supplying pilot pressure to the steering valve (25) according to a handle operation, a lever electromagnetic control valve (27) for supplying pilot pressure to the steering valve (25) according to a joystick operation, and a handle prioritization valve (28). The handle prioritization valve (28) shuts off pilot hydraulic pressure supplied to the steering valve (25) from the lever electromagnetic control valve (27) due to a differential pressure in a hydraulic circuit that is produced by operating fluid flowing through the orbit roll (26) during a handle operation.
