A method for folding a driver airbag may include: forming a tuck-in folding part by pushing an upper end portion of an airbag cushion part into the airbag cushion part; folding the tuck-in folding part toward the opposite side with respect to a driver seat; temporarily attaching the tuck-in folding part to the airbag cushion part; injecting gas into the airbag cushion part, and compressing the airbag cushion part such that the airbag cushion part maintains a plate shape; and folding the airbag cushion part while moving a folding jig disposed in a radial shape around the circumference of the airbag cushion part toward an inflator connection part.
