Patent attributes
An accelerator pedal apparatus includes a pedal arm having an accelerator pedal, a housing rotatably supporting the pedal arm between a rest position and a maximum depression position, a first return spring exerting urging force to return the pedal arm toward the rest position, a reaction force adding mechanism adding reaction force opposed to tread force of the accelerator pedal; and the reaction force adding mechanism includes a movable member arranged movably against the housing while receiving reaction force of the first return spring, a reaction force spring arranged between the movable member and the pedal arm as being capable of generating reaction force against the tread force, and a lock mechanism being capable of locking the movable member not to be movable at desired timing, so that fuel consumption can be improved by exerting resistance force to driver's depressing operation to suppress excessive depression.
