PROBLEM TO BE SOLVED: To provide a drainage system for an elevator, capable of automatically and speedily discharging drain from the air-conditioners of a plurality of cages, in an elevator of one-shaft multi-car system.SOLUTION: Each of cages 20a, 20b comprises: a water storage tank 23 that stores drain from an air conditioner; a drain pipe 25 having a drainage port and a drain valve 26 that discharge water stored in the water storage tank, downwards; a water receiving port 27 which is provided in such a way that it can receive drain from the drainage port of the drain pipe of an immediately above cage and which guides the received water to the water storage tank of its own cage; and detecting means which detects that water in the water storage tank has reached a prescribed quantity or more. Each cage also includes control means configured in such a way that a drainage cage which is a cage from which water equal to or more than the prescribed quantity has been detected by the detecting means and a receiving cage which is a cage immediately below this drainage cage, are stopped at vertically adjacent floors, then the drain valve 26 of the drainage cage is opened.
