Foldable pedal device for autonomous vehicle

A foldable pedal device for an autonomous vehicle, comprising:

• a pedal pad mounted to penetrate a vehicle body panel, disposed in a space below a driver seat to separate an engine compartment space and a passenger compartment space from each other, the pedal pad being configured to be engaged by a driver and to be changed between a hidden state, in which the pedal pad is introduced into the engine compartment space, and a popped-up state, in which the pedal pad protrudes into the passenger compartment space;
• and
• an actuator configured to generate power to rotate the pedal pad to cause the pedal pad to enter the hidden state or the popped-up state,
• wherein the pedal pad includes:
• a body portion penetrating a panel aperture formed in the vehicle body panel;
• a rear surface formed to cover a back side of the body portion and to be engaged by the driver;
• and
• a front surface formed to cover a front side of the body portion, and
• wherein an overall size of each of the rear surface and the front surface of the pedal pad is set to be larger than a size of the panel aperture so that the rear surface or the front surface seals the panel aperture in the hidden state or the popped-up state of the pedal pad.
