Claims

[Claims for Utility Model Registration] (1) Connection between one shaft end of an Exit roll immersed in a molten plating bath and a transmission shaft connected to the output shaft of an electric motor installed outside the molten plating bath. In the shaft joint interposed in the part, the shaft end and the base end of the transmission shaft connected thereto are each bifurcated,
A plating bath characterized in that the bifurcated pieces of the two shafts are connected via a cross pin so as to be orthogonal to each other, and at least the outer surface of the arm of the cross pin is made of Si ₃ N ₄ or SiC ceramic material. universal joint. (2) A universal joint in a plating bath according to claim 1, characterized in that a sliding bearing or a rolling bearing made of Si ₃ N ₄ or SiC ceramic material is attached to the arm support portion of the cross pin in the universal joint according to claim 1.
