An airbag apparatus for a vehicle, comprising: an airbag cushion; a vent hole formed in the airbag cushion to discharge inflating gas therefrom; a cover provided on an outer surface of the airbag cushion, the cover being adjustable between a state in which the cover is spaced apart from the vent hole to open the vent hole by an imparted tensile force, and a state in which the cover comes into close contact with the vent hole to close the vent hole; a tether connected at a first end to the cover and secured at a second end to an interior of the airbag cushion to impart a tensile force to the cover through the vent hole; a tether guide provided on an inner surface of the airbag cushion to support the tether, the tether passing through the tether guide and being slidable along the inner surface of the airbag cushion; and sealing means provided between the vent hole and the tether guide to support the tether, the tether passing through the sealing means after passing through the tether guide, wherein the tether supported on the tether guide is sewn to at least one of the tether guide and the airbag cushion to form a temporary seaming line, the sewn temporary seaming line being torn off in an initial deploying stage of the airbag cushion.
