  • Patent number: 10549724
    Abstract: An ejection nozzle member attached to a vehicle-mounted camera is formed from an elastic material, and includes a cover member mounted on an upper surface of a casing, the cover member having therein an air passage to which compressed air is supplied. A pair of seal members are formed in an air ejecting unit, from which the compressed air is ejected, on outer sides of the air passage in a widthwise direction. The seal members are formed in lip shapes, protruding downward and toward the center in the widthwise direction on a side of the air passage. When the ejection nozzle member is attached to the camera, distal ends of the seal members are placed in contact mutually on the side of the air passage, and are pressed toward the casing by the compressed air that flows in the air passage to thereby be placed in intimate contact therewith.

  • Publication number: 20170355353
    Abstract: Of moving directions of a piston, the direction in which high-pressure air is delivered is a delivery direction, and the direction in the opposite direction from the delivery direction is a force accumulation direction. The piston is moved in the force accumulation direction by the moving mechanism, and moved in the delivery direction by the biasing force of the biasing spring in response to the release of the moving force exerted by the moving mechanism. The cylinder is provided with: a piston supporting portion that supports the piston; and a connection protrusion that has a delivery path for delivering the high-pressure air to the nozzle. The inner surface of an end of the piston supporting portion in the delivery direction is formed as a closed surface. The delivery path is located further toward the force accumulation direction than the closed surface is.
