<P>PROBLEM TO BE SOLVED: To provide a drain infiltration environmental simulation device of a reciprocation wear test apparatus wherein water droplets are simulated as drain can be supplied to a sliding surface of a test piece with supply timing, a supply frequency and a supply quantity varied arbitrarily and accurately, and the spread of the water droplets outside the sliding surface can be restrained even in the case that there is almost no extra space around each test piece in the reciprocation wear test apparatus wherein the two test pieces are each fixed to different rigid members so as to slide relatively to each other. Ž<P>SOLUTION: The drain infiltration environmental simulation device includes: a water injection nozzle 14 for injecting and supplying the water droplets to the sliding surface of the test piece from a separated position; a water supply pipe 16 for supplying pressurized water to the water injection nozzle from a distance; a pressurized water tank 18 for storing the pressurized water pressurized by pressurized air and supplying the pressurized water to the water supply pipe; a two-port valve 20 which is provided in the water supply pipe in order to close the flow of the pressurized water in an openable and closable manner; and a valve control device 22 for controlling the two-port valve.
