A suspension conveying device according to the present invention includes screw shafts of two suspension line pulling-up/feeding mechanisms in a conveying traveling body. The screw shafts have low-speed drive regions, in which feed pitches for driven bodies are small, and high-speed drive regions, in which feed pitches for the driven bodies are large. The screw shafts are installed so that the low-speed drive regions and the high-speed drive regions are disposed mutually oppositely as viewed from the driven bodies when a conveyed object supporter is at one end of an elevation/lowering stroke, and the conveyed object supporter is tilted in a middle of the elevation/lowering stroke when the screw shafts are driven to undergo forward/reverse rotation at a fixed speed by a motor.

An immersion-type surface treatment tank includes a treatment tank body including: a single tank internal space elongated in a plan view, and a nozzle that ejects an electrodeposition paint into the tank internal space. The treatment tank body includes: a first tank inner side surface extending along a longitudinal direction of the tank internal space; a second tank inner side surface facing the first tank inner side surface and extending along the longitudinal direction; and a rectifying plate that is formed halfway in the longitudinal direction and changes a flow direction of the electrodeposition paint such that the electrodeposition paint flowing horizontally along the first tank inner side surface is directed toward the second tank inner side surface. The rectifying plate changes the flow direction of the electrodeposition paint, thereby forming, in the tank internal space, at least two horizontal swirl flows adjacent to each other in the longitudinal direction.
