Auxiliary buffer envelope device for inner pad of safety helmet, including at least one attachable buffer envelope disposed on a section of the inner pad near the rear bottom edge thereof. The buffer envelope is filled in the gap between the rear side of the inner pad and the curve of the rear lower dented part of a user's skull. The buffer envelope enables a user to more snugly wear the helmet with better fixing and shakeproof effect. The buffer envelope reversely retain rear dented part of, the user's skull so as to more reliably prevent the helmet from detaching from the skull and provide a fixing and protective effect for the head of the user. The buffer envelope has simple structure and can be easily connected with the helmet.
