However, when a small metal part is cleaned using a conventional cleaning device of this kind, it is only necessary to put the metal part into a rotating basket and apply ultrasonic vibrations while rotating the metal part. At the time of washing, the metal parts in the rotating rotating basket are stationary and rotate with the weight or centrifugal force overlapping and sticking to the bottom and the peripheral wall of the basket. For this reason, even if ultrasonic vibration is applied to the cleaning liquid, it does not reach the inside of the overlapping metal parts, and dirt such as oily dirt and fine powder remains on that part, causing uneven cleaning of the object to be cleaned. There was a problem that cleaning could not be performed well.

As for d, as shown in FIG.
Samples Nos. 5 and 26 were cleaned using a cleaning device arranged on the ultrasonic generator 13 side, and their dirt removal rates were determined. The removal rate in that case was compared with the example in Table 2 above. The results are shown in Table 3. From Table 3, both obtained a good dirt removal rate of about 90% or more. However, depending on the shape of the object to be cleaned, as shown in FIG. It can be seen that the removal rate is better when the nozzles 15 and 16 are provided on the side opposite to the ultrasonic generator 13 than when the injection nozzles 25 and 26 are disposed on the ultrasonic generator 13 side as shown in FIG. .
