Abstract
A hinge positioning apparatus for a foldable mobile telephone has a shaft, a set angle device and a biasing member. A washer is mounted on one end of the shaft. The set angle device has a stationary sleeve with a concave groove and a retractable sleeve with a convex ridge. The convex groove of stationary sleeve is rotatably attached to the concave ridge of the retractable surface. The biasing member is mounted around the shaft and mounted between the retractable sleeve and the washer. With such a hinge positioning apparatus, the hinge positioning apparatus can be used for an extended life without permanently deforming the biasing member inside the hinge positioning apparatus.
