PURPOSE:To eliminate the need for a device for making setting and resetting operations with each dip treating material and moving a conduit in follow-up thereto by providing a mechanism which introduces air into the recess of the dipping material by using an air supplying pipe from along side said material in the outlet part of a treating tank. CONSTITUTION:A compressed air supplying device 18 is disposed atop 2a an electrodeposition vessel 2 along the outlet part thereof, and the air supplying pipe 10 of the device 18 is bent downward so as to extend downward into an electrodepositing liquid 6. The bottom end part 10a thereof is bent transversely toward the window opening 1c alongside a cabin 1. A short sized flexible pipe 19 of which the top end 19a is approachable to the side face of the cabin 1 is mounted to the bottom end part 10a so that said pipe is normally held in the suspended position (a) and is displaced to a horizontal position (b) by the ejecting output of compressed air when said air is supplied to introduce the ejected air though the opening 1c of the cabin 1 into a recess 1b. When the cabin 1 passes alongside the device 18 in this stage, the air is ejected for a specified time, by which the air is supplied at a prescribed rate into the recess 1b.
