Accelerator pedal apparatus

The accelerator pedal apparatus includes a pedal arm 30 rotating around a first rotation axis line S1, a return spring 40 and a reaction force adding mechanism (i.e., a drive source 60 and a rotation member 70 rotating around a second rotation axis line S2 and having a contact portion 71 contacted to the pedal arm) which adds reaction force in the direction to return the pedal arm to the rest position; and then, first distance from the contact position of the pedal arm with the contact portion to the first rotation axis line is longer than second distance to the second rotation axis line, and the pedal arm includes a contact section 35 having the contact portion displaced while being contacted so that the contact portion is to be farther from the first rotation axis line when rotating toward the maximum depression position and to be closer to the first rotation axis line when rotating toward the rest position; so that active control with quick response can be performed while achieving miniaturization.
