PURPOSE: A chrome plating jig is provided to improve quality of the shaft by dispersing anions that are centralized upon both ends of a shaft due to electrical characteristics of chrome plating, thereby uniformly maintaining tolerance control all over the shaft. CONSTITUTION: The chrome plating jig is characterized in that chrome plating is covered on all over a material to be processed by adhering a plating jig(2) of 80 to 110 mm that is above the length showing measurement deviation onto both ends of the material to be processed to appropriately disperse anions concentrated upon both ends of the material to be processed into both ends of the jig, wherein the jig is composed of a circular nut having the same outer diameter as the material to be processed for the most ideal ion distribution, and the jig is composed of an electrode connecting I bolt(4).
