A steering wheel air bag module mounting structure comprises a steering wheel framework and an air bag shell, and at least three damping units are arranged between the steering wheel framework and the air bag shell. The damping unit comprises a fixing pin, a damping sleeve and a reset spring, and is characterized in that the fixing pin is sequentially sleeved with a guide hook, a bearing base and a guide sleeve from top to bottom; the guide hook penetrates through the damping sleeve, first hooks are uniformly distributed on the circumference of the lower end of the guide hook, first clamping windows and second clamping windows are uniformly distributed on the bearing base, and the first hooks are respectively clamped in the corresponding first clamping windows; the guide sleeve is positioned and inserted into a corresponding insertion hole in the steering wheel framework, second hooks are uniformly distributed on the circumference of the upper end of the guide sleeve, and the second hooks are clamped in the corresponding second clamping windows and can slide along the second clamping windows; the reset spring is arranged on the outer edge of the bearing base in a sleeving mode and clamped between the bearing base and the guide sleeve. The structure can effectively reduce or eliminate the shaking of the steering wheel, improves the holding comfort of a driver, and is good in vibration reduction effect.
