PURPOSE: A lower clamp of a hanger for supporting a printed circuit board on a plating device is provided to prevent a lower support bar of a hanger from being separately elevated when loading the printed circuit board by largely rotating a locking lever in order not to generate corrugation. CONSTITUTION: A lower clamp of a hanger comprises a conducting contact point(2), a locking lever(3), a push lever(4), a hinge hole, and a spring. The conducting contact point is formed at the front ends of the push lever and the locking lever. The locking lever and the push lever are integrated across the hinge hole. The hinge hole is formed between the locking lever and the push lever. The push lever is elastically supported by the spring.
