A nozzle structure of a bidet with swirling water current is provided, in which a user controls water spraying angle of water current sprayed from an outlet of a cleaning nozzle, and the water current with swirling force is sprayed in a circular pattern without causing an eccentricity, thereby increasing cleaning power and reducing water consumption. The nozzle structure of a bidet includes a water channel unit with two internal water channels classified as a wide flow channel and a linear flow channel a cleaning nozzle tip where water current passed through the wide flow channel and water current passed through the linear flow channel are combined and spouted, wherein the cleaning nozzle tip is connected to an end of the water channel unit and a fluid mixing unit arranged in an upper portion of an interior of the cleaning nozzle tip such that the fluid mixing unit applies a torque to the water current flowing upward after passing through the wide flow channel and the linear flow channel so as to thereby generate swirling forces of water current. It is possible to prevent an eccentricity of water current and control the water spray angle to be maintained at a constant level, while generating swirling water current with varying swirling forces of water current spouting from the outlet of the cleaning nozzle tip. This enables a user to change his or her body parts contacting the water current even without moving his or her body, and increases in cleaning power.
