Abstract:
A washing nozzle according to the present disclosure comprises a shower head (11) that sprays pressurized washing water. The shower head (11) comprises a swirl chamber (14), an inflow port (12), and a discharge port (13). The swirl chamber (13) has a substantially cylindrical side wall and forms a swirl flow. The inflow port (12) causes the washing water to flow into the swirl chamber (14) in an oblique direction along the side wall of the swirl chamber (14). The discharge port (13) is provided to one surface of two surfaces of the swirl chamber located in a direction along the center axis of the swirl chamber (14) and discharges the washing water. The swirl chamber (14) comprises a spherical body (17) and a guide groove portion (18). The guide groove portion (18) supports the spherical body (17) at a position which has a height equal to or lower than the radius height of the spherical body (17). The guide groove portion (18) causes the spherical body (17) to reciprocate by the swirl flow.
