PROBLEM TO BE SOLVED: To provide a sliding bearing mechanism capable of utilizing a characteristic of a rotary sinker that a wire is hard to scar and reducing generation of vibration caused by largeness of a clearance between a rotation bearing and a fixed shaft. SOLUTION: The sliding bearing mechanism immersed in a molten metal bath is composed of the rotation bearing 1 having a space 7 whose cross section vertical to the shaft includes a round shape, and the fixed shaft 2 penetrating the rotation bearing 1. The sliding bearing mechanism is characterized by a shape of the fixed shaft 2 which contacts the rotation bearing 1 at two positions on the cross section vertical to the shaft. As the rotation bearing 1 can keep a state of balancing force thereby without changing its position even when magnitude of line tension changes, the present invention can continue to rotate at the stable position without generating deviation of the rotation bearing.
