The invention provides a coated-type rotating shaft structure, which comprises a shaft cylinder, a coating piece and a pivot, wherein the shaft cylinder has a periphery nick; a groove is arranged inside the nick; the coating piece has a coating end and an extending end; a cut groove is arranged on the coating end; a frame and a ring groove are arranged between the coating end and the extending end; the pivot is pivoted on the coating piece; the front end of the pivot is provided with a convex ring; the back end of the pivot is inlaid in a shaft hole of a fixing seat; the extending end of the coating piece can be fixed in the groove of the shaft cylinder; the convex ring of the pivot can push against the frame and the ring groove of the coating piece; and when the shaft cylinder and the fixing seat relatively rotate, the coating piece can produce friction torque on the pivot. The structure has the advantage of preventing the pivot, the coating piece and the shaft cylinder from being disengaged and separated.
