Electrodeposition coating facility

An electrodeposition coating facility comprising:

• conveyor means for conveying articles to be coated,
• hanger means each suspended from the conveyor means for carrying an article to be coated and formed into an L-shaped configuration composed of a vertical portion and a horizontal portion,
• hanger support roller means, each disposed at or near the lower end of said L-shaped hanger means, and
• guide rail means laid along an electrodeposition coating line for guiding and holding said hanger support roller means, in which
• said guide rail means is laid so as to pass through a cleaning vessel disposed subsequent to an electrodeposition vessel, and rotational driving means is disposed for a predetermined length along an intermediate path of said guide rail means immersed in said cleaning liquid in said cleaning vessel so that the hanger support roller means is caused to abut against and thereby rotated compulsorily by said rotational driving means.
