Abstract
A vehicle airbag apparatus in which a frame and reinforcement members can be vibration-welded to an instrument panel with uniform strength and without distortion or discoloration of the instrument panel cover caused by the vibration welding. First weld ribs on a frame and second weld ribs on reinforcement members joined to the frame have a length which extends in the direction of vibration welding. The lengths of the first weld ribs and the second weld ribs extending in the vibration direction are set to be three times or more as long as an amplitude of the vibration welding. Passages for flowing a cooling fluid along the first weld ribs are provided on the joining surfaces of the joint flange, and furthermore, passages for flowing the cooling fluid along the second weld ribs may be provided on the joining surfaces of the reinforcements.
