<p>PROBLEM TO BE SOLVED: To provide a nozzle of good operability which never stick too strongly to a surface to which a matter to be suck is stuck whatever state the surface is in and to provide the nozzle the inner pressure of which never changes quickly though the nozzle is moved away quickly from the surface to which the matter to be suck is stuck. SOLUTION: The structure of the nozzle connected to a suction device to be used for sucking the matter to be sucked is provided with a cylindrical nozzle main body part having an opening for sucking the matter to be sucked formed on the side of one end, a suction port part mounted to the opening side of this nozzle main body part and having an opening formed on a surface opposing the opening, and a liquid jetting part arranged inside of the nozzle main body part and constituted as to be able to jet the liquid at need to the matter to be sucked opposing the opening surface of the nozzle main body part. The suction port has a sidewall part overlapping with at least a part of the outer peripheral surface of the nozzle main body part, and a gap is formed between this sidewall part and the outer peripheral surface of the nozzle main body part so as to suck outside air from the opening of the nozzle main body part via the gap.</p> |
