PROBLEM TO BE SOLVED: To provide equipment for drain treatment of refrigerating showcase in which drain let out of a case body in the inside of the base flows smoothly to an overflow outlet, dusts and the like contained in the drain do not adhere to an evaporation mat. SOLUTION: A drainpipe 7 and a drain outlet 17 are provided near a drain reservoir R. As the result, dusts and the like in the drain flowing down through the drainpipe 7 do not pass an evaporation mat 8, and accumulated in the reservoir R. The drain flows from the reservoir R to the outlet 17. So the dusts and the like do not adhere to the mat 8, and the mat can maintain the evaporation function for a long period of time.
