A pivot hinge for a portable electronic device is disclosed. A base plate with a pivot tube is fixed on the main unit of the portable electronic device, and a locating bracket is fixed on the movable display panel. A shaft is inserted through the pivot tube, exposing the angular section from the other end of the pivot tube. A locking piece, a spring, and a ring are sequentially inserted over the angular section to complete the spring assembly. The interlocking of the tooth and notch enables the movable display panel to be placed in the horizontal direction over the main unit. A middle section of the shaft and the pivot tube are closely mated only when two plain facets respectively formed on the shaft and the pivot tube are matched up in the rotation of the shaft, thus abrasion damage is significantly reduced.
