1. An accelerator device comprising:
a pedal lever configured to operate in accordance with a stepping operation;
a reaction force adjuster driven by an actuator and capable of adjusting a reaction force that is a force in a direction of pushing back the pedal lever; and
a controller including:
a target operation amount setting unit configured to set a target operation amount of the pedal lever in accordance with a vehicle speed; and
a drive control unit configured to control a drive of the actuator,
wherein the controller is configured to control the reaction force in accordance with the target operation amount of the pedal lever so as to make an operation amount of the pedal lever to be within a target range, when switching from an automatic drive to a manual drive,
wherein the controller is configured to control the reaction force adjuster such that the reaction force becomes larger when the operation amount of the pedal lever reaches the target range, than that before reaching the target range, and
wherein the controller is configured to perform a reaction force return control in which the reaction force returns to an initial state by gradually changing the reaction force, when the operation amount of the pedal lever is stabilized within the target range.
