A pivot bearing mechanism includes a main body and a pivot shaft. The main body is fixedly mounted on a first member, and is provided on a top thereof with an axially extended slit and near the top with an internally threaded hole transversely extended through the slit, such that a screwing element can be tightened into the threaded hole to narrow the slit. The pivot shaft has a first end rotatably supported on the main body and a second end fixedly connected to a second member. By tightening the screwing element into the threaded hole by different degrees, the slit is forced to narrow or widen to allow adjustment of a tightness of contact between the main body and the pivot shaft, allowing the pivot shaft to bring the second member to rotate and locate at a desired position, relative to the first member.
