PROBLEM TO BE SOLVED: To provide a washer device for a vehicle capable of properly spraying washing fluid on a target watering area, while saving injection flow rate of the washing fluid by a single washer pump according to a traveling state or a parking/stopping state of the vehicle. SOLUTION: A motor pump 12 of the washer device 10 is capable of alternatively discharging the washing fluid from high pressure side discharge port 22 and low pressure side discharge port 24 with discharge pressure set to be different with each other. At the time of a high speed traveling of the vehicle, the washing fluid is discharged by high pressure by the motor pump 12 to inject liquid particles having high flow rate from a nozzle 16 for a high speed time, and moving amount (transition amount from a target watering point) of the watering area by an influence of air current is reduced. Since the influence of air current is originally reduced at the time of a low speed traveling time or the parking/stopping time of the vehicle, the washing fluid is discharged by low pressure by the motor pump 12, liquid particles having comparatively slow flow rate are injected from a nozzle 14 for a low speed time, and the washing fluid can be sprayed on the target watering area, while saving injection flow rate of the washing fluid.
