A device for spraying a fluid on a vehicle camera includes a flow passage for connecting a suction portion with a discharge portion; a cylinder for communicating a pressure chamber in front of a piston with the flow passage; a drive mechanism for the piston including a motor; a first valve located between the suction portion and the pressure chamber, and functioning such that the first valve opens when the piston moves backward and closes when the piston moves forward; a second valve located between the pressure chamber and the discharge portion, and functioning such that the second valve opens when a pressure in the pressure chamber reaches a predetermined value by a forward movement of the piston; and a casing for housing the flow passage, the cylinder, the drive mechanism, the first valve, and the second valve to be combined with the vehicle camera.
