1. A foldable accelerator pedal apparatus for a vehicle, the foldable accelerator pedal apparatus comprising:
a pedal housing;
a pedal pad having a first end rotatably coupled to the pedal housing and manipulated by a foot of a driver;
a hysteresis module having a first end rotatably installed on the pedal housing at a fixed position in the pedal housing and configured to generate hysteresis when the driver manipulates the pedal pad;
a straight type motor fixedly installed in the pedal housing and including a motor rod configured to advance and retreat; and
a rotation link rotatably coupled to the pedal pad, connected to the motor rod, and configured to contact the hysteresis module when the motor rod retreats and to be disconnected from the hysteresis module when the motor rod advances,
wherein the pedal pad is configured to switch between a hidden state and a pop-up state when the motor rod advances and retreats, and
wherein in the hidden state, the pedal pad is inserted into the pedal housing, and in the pop-up state, the pedal pad protrudes from the pedal housing.
