1. A working machine provided with a cab for its operator to ride in, comprising:
a projection device that projects image light to form an image of cautions to an operator who operates the working machine;
a combiner that displays image light projected by the projection device;
a controller that controls the projection device; and
a gate lock lever that allows the operator to switch between a locked state in which operation of the working machine is disabled and an unlocked state in which operation of the working machine is enabled;
wherein in a case where the gate lock lever is in the unlocked state, the controller displays the cautions on the combiner in a second display manner in which the cautions are more likely not to obstruct the view of the operator than in a first display manner of displaying the cautions in a case where the gate lock lever is in the locked state.
