Nozzle for cleaner

A nozzle for a cleaner, comprising:

• a nozzle housing having a suction flow path extending in a front-rear direction for suctioning air;
• a rotation plate provided below the nozzle housing so as to be rotatable, a mop being attachable to the rotation plate;
• a water tank provided to the nozzle housing and configured to supply water to the rotation plate;
• a water supply flow path formed inside the nozzle housing and configured to guide water in the water tank to the rotation plate;
• and
• a water discharge port defined as an outlet of the water supply flow path and formed to penetrate a bottom surface of the nozzle housing in a vertical direction,
• wherein the rotation plate includes a water passage hole formed to vertically penetrate the rotation plate so as to receive water discharged downward from the water discharge port,
• wherein the water passage hole is formed such that a through space thereof extends from a minimum radius (R2) to a maximum radius (R3) about a rotational axis of the rotation plate, and
• wherein a radius (R4) from the rotational axis to a center of the water discharge port is greater than the minimum radius (R2) of the water passage hole and smaller than the maximum radius (R3) of the water passage hole.
