PURPOSE: An unloader valve device for an air cleaner is provided to sense water flowed into an air cleaner and staying in the air cleaner, and forcibly discharge the sensed water. CONSTITUTION: An unloader valve body(110) discharges liquid flowed into an air cleaner(100). A sensor part(120) is installed inside the unloader valve body for sensing the existence of liquid and outputting an electric signal. A driving element opens and shuts the unloader valve body. An engine control unit(140) controls the driving element according to the signal of the sensor part to open the unloader valve body. Water staying in the unloader valve body is discharged to the outside by opening the unloader valve body.
