Abstract

A nozzle (7) to clean the lens surface (1a) of the camera (1) is provided. The nozzle (7) includes a cleaning fluid path (11a), (11b) leading to the cleaning fluid. to the discharge port (10a),(10b) and air passage (12) leading the compressed air to the discharge port (10a), (10b). In addition, the distal end of the cleaning fluid path and the far end of The air passages were arranged so that they were close to each other. or are arranged to converge to each other. Therefore, at the time of cleaning the lens surface (1a), compressed air is injected. is the range from the channel to the end and the cleaning liquid is sucked by the induced negative pressure. This is due to the injection of compressed air to make the cleaning liquid injected intermittently from the discharge port, thus cleaning the lens surface (1a).
