This accelerator pedal apparatus includes a pedal arm (20) having an accelerator pedal (24), a housing (10) supporting the pedal arm so as to pivot about a predetermined axis line (S) between a rest position and a maximum pressure position, a slider (30 ) sliding over an inner wall (11d) of the housing, a contact part (25) formed on the pedal arm for applying compressive force while releasably contacting the slider, and a pressure applying spring (40) is arranged between the housing and the slider, so that the pressing force which presses the slider against the inner wall (11d) and the contact part (25), increases in accordance with the depression of the accelerator pedal. This makes it possible to achieve the desired hysteresis of the thrust while reducing, and so on.
