1. A work machine comprising:
a vehicular body frame having a rear frame and a front frame rotatably coupled to the rear frame;
a steering actuator that changes an angle of the front frame with respect to the rear frame; and
a steering operation device operated by an operator to operate the steering actuator, the steering operation device including:
a joystick that receives an operation performed by the operator;
at least one electric lever that has a main body unit and a lever unit tiltable with respect to the main body unit and outputs a tilt angle of the lever unit with respect to the main body unit; and
an input unit that inputs an input to the lever unit to tilt the lever unit with respect to the main body unit,
the input unit having at least one elongated hole extending in an orthogonal direction orthogonal to a direction in which the operator tilts the joystick,
the lever unit being disposed in the elongated hole.
