The invention provides an automobile steering wheel airbag applied to the technical field of automobile safety airbags. The edge of an airbag upper main piece (3-1) of an airbag main piece (3) of the automobile steering wheel airbag is connected with the edge of an airbag lower main piece (3-2), the airbag upper main piece (3-1) comprises an upper main piece upper semicircle (3-3) and an upper main piece lower semicircle (3-4), the upper main piece upper semicircle (3-3) and the upper main piece lower semicircle (3-4) are both of a semicircular structure, a diameter size of the upper main piece upper semicircle (3-3) is larger than a diameter size of the upper main piece lower semicircle (3-4), and a connecting position of the upper main piece upper semicircle (3-3) and the upper main piece lower semicircle (3-4) is arranged as a connecting structure of a radius gradual transition (3-5). According to the automobile steering wheel airbag, the cost is not additionally increased; after the steering wheel airbag is unfolded, the head of a driver can be protected; meanwhile, the chest of the driver is prevented from being squeezed, so that the safety of the driver is protected, potential safety hazards during accidents are eliminated, and the quality of a whole automobile is improved.
