Proposed is an air mixing nozzle tip structure which improves productivity while simplifying the structure by being configured so that air is introduced through an air mixing inlet and discharged together with wash water, improves cleaning power while realizing a massage effect because fine water droplets are formed in the process that wash water and air are combined and discharged, controls the inlet amount of air by forming the air mixing inlet on one side or each of opposite sides of a nozzle tip cover or by adjusting the cross-sectional size of the air mixing inlet, and promotes product stability by providing an air supply passage at the rear of the air mixing inlet so that the air introduced through the air mixing inlet is smoothly discharged to a wash water ejection hole through an air guide.
