Abstract
A ramp apparatus for a vehicle includes a ramp retractable in the vehicle and drawable to an outside of the vehicle, a moving body movable in a drawing direction and a retracting direction together with the ramp, a support arm rotatably coupled with the ramp at a first rotatable coupling point and rotatably coupled with the moving body at a second rotatable coupling point, and a tension spring interposed between the ramp and the moving body. The ramp is arranged in a lifted-up position in which the ramp faces a door opening of the vehicle from a drawn position. The tension spring rotationally urges the first rotatable coupling point positioning above the tension spring in the drawn position of the ramp about the second rotatable coupling point and exerts an urging force on the ramp, the urging force moving the ramp from the drawn position toward the lifted-up position.
