Abstract:
An articulated wheel loader (1) that has a front frame (11) and a rear frame (12) that are connected and that comprises a joystick lever (24), a force application part (27), and a control part (28). The joystick lever (24) is moved right or left when operated by an operator and thereby changes the steering angle (θs) of the front frame (11) with respect to the rear frame (12). The force application part (27) applies assistance force or reaction force to operation of the joystick lever (24) by the operator. The control part (28) controls the force application part (27) such that the latter makes the operation force required when the joystick lever (24) is moved left different from the operation force required when the joystick lever (24) is moved right.
