A self-locking structure of threaded connection for installing a step roller of an escalator on a step is provided. The step has a mounting shaft on which the step roller is installed through a rolling bearing; a threaded connection structure including a bolt, a washer and a nut, wherein the mounting shaft has a through hole along its axis line direction, the bolt passes through the washer, the through hole and the nut, and the washer presses the inner ring of the rolling bearing against the mounting shaft through the tightening engagement between the bolt and the nut. A countersunk slot hole for placing the nut is formed at the end of the through hole such that the bolt passes through the nut located in the countersunk slot hole. The sidewall of the countersunk slot hole includes a bottom face and two side faces forming a U-shaped structure.
