<P>PROBLEM TO BE SOLVED: To provide a nozzle device for a vehicle-mounted camera that can efficiently distribute compressed air even to a downstream range over the top part of a lens surface of a convex lens. <P>SOLUTION: The nozzle device 12 for a vehicle-mounted camera 3 is for supplying compressed air A to a lens surface 5a of a convex lens 5 of the vehicle-mounted camera and removing foreign materials attached to the lens surface 5a. The nozzle device 12 for the vehicle-mounted camera includes an injection port 26 for injecting the compressed air A to the lens surface 5a from an outer circumference part of the convex lens 5. Further, the nozzle device 12 for the vehicle-mounted camera is formed with a branched flow path 29 provided to a position below the convex lens 5 in a downstream of the compressed air A, and a branching protrude part 28 for branching the compressed air A injected from the injection port 26 into the inside of the branched flow path 29 and an outside the branched flow path 29. <P>COPYRIGHT: (C)2013,JPO&INPIT |
