ACCELERATOR DEVICE

An accelerator device includes a pedal lever, a drive source, a power transmission mechanism, and a control unit. The pedal lever is operable in response to a pedaling operation. The drive source generates a driving force when being energized. The power transmission mechanism transmits the driving force of the drive source to the pedal lever, and applies a reaction force in an opposite direction to a pedaling direction of the pedal lever. The control unit includes a reaction force controller that controls the reaction force applied to the pedal lever by controlling the drive source. The reaction force controller holds an initial reaction force for a reaction force hold time from a start of reaction force application, and performs a reaction force reduction control in which the reaction force is reduced as a time function after an elapse of the reaction force hold time.
