PROBLEM TO BE SOLVED: To provide a solution leakage preventive mechanism of a plating equipment which is capable of uniformly sealing the upper part to the lower part of a seal regardless of the volume of the solution and makes it possible to obtain good sealing performance by a simple mechanism without using air pressure, or the like. SOLUTION: The side walls of a treating vessel body 1 through which a work is put in and out are provided with slits 2 and 3 in a perpendicular direction and two pieces one set of columnar rolls 4 and 4 as well as 5 and 5 are perpendicularly disposed within the treating vessel body 1 in proximity to the slits 2 and 3 in the state that these rolls are movable horizontally with each other Two pieces one set of the columnar rolls 4 and 4 as well as 5 and 5 are adapted to be attracted to each other by magnetic force. The rolls 4 and 4 as well as 5 and 5 are housed within compartments 6 and 7.
