Accelerator pedal apparatus

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