Safety shaft includes wobbler heads with shanks, one of which is assembled coaxially in the axial opening of another shank with a clearance, in which is mounted an elastomer bushing compressed in axial direction. The shank and axial opening are equipped with conical parts. In this case, the surface of the conical part of opening has reverse conicity with respect to the conical part of the shank, and the form of bushing corresponds to the form of the clearance formed between them.
