ACCELERATOR PEDAL DEVICE

An accelerator pedal apparatus of the present invention includes, as a reaction force adding mechanism to add reaction force against pedaling force of an accelerator pedal, a rotation member (40) which is rotatable relatively against a pedal arm, a locking mechanism (50) which is capable of locking the rotation member when the accelerator pedal is at an arbitrary depression position, and an intermittent interlocking member (60) which intermittently interlocks the rotation member with the pedal arm so that the rotation member is interlocked with the pedal arm when the locking mechanism is not in operation and reaction force is added against depressing operation of the accelerator pedal under operation of the locking mechanism while rotation of the pedal arm is allowed with release of interlocking of the rotation member and decrease or elimination of the reaction force owing to elastic deformation caused by pedaling force which overcomes the reaction force. With the above, reaction force can be added at an arbitrary depression position and eco-driving capable of achieving fuel consumption improvement can be performed.
