PROBLEM TO BE SOLVED: To provide a nozzle for cleaning a bottle, with which the bottle can be cleaned by bringing a cleaning liquid into full contact with the inside of the bottle without exchanging a type of the nozzle even when the bottle has a different mouth diameter, unevenness such as a rib or a quadrangular cross section having corner parts. SOLUTION: A central injection pipe 5 having the diameter smaller than the outside diameter of a nozzle body 2 of this nozzle is erected at the upper end of the nozzle body 2 having an injection flow passage in the axial center direction and a first jet orifice 7 is arranged at the tip of the central injection pipe 5 for jetting the cleaning liquid vertically. A second jet orifice 9 is formed in the base part of the central injection pipe 5 for jetting the cleaning liquid obliquely upward. A discharge controlling means is formed in the outer peripheral part of the nozzle body 2 under the second jet orifice 9. As for the discharge controlling means, a plurality of third jet orifices 10 can be arranged in the peripheral wall part of the nozzle body for jetting the cleaning liquid obliquely upward, or a disk-shaped body projected from the peripheral wall part of the nozzle body in a flange-like shape, which is larger than the mouth diameter of the bottle to be cleaned, can be arranged.
