PURPOSE: To reduce the movable parts lowering the air cleanlines in a cleaning chamber and acting as a dust generating source increasing the concn. of impurity in a cleaning solution as few as possible directly above a cleaning tank by dividing a carrier feed means into the shaking arm connected to a lift mechanism and a traverse mechanism.

CONSTITUTION: The falling of a carrier 7 to a cleaning tank 2 and the drawing-up thereof from the cleaning tank 2 are realized by a shaking arm 4 and the horizontal transfer of the carrier 7 is realized by a traverse mechanism 9. The height position stopping the shaking arm 4 is different between such a case that the carrier 7 is transferred horizontally so as to get over a high partition wall and such a case that the carrier 7 is merely transferred horizontally at the same height and this change over is performed by a clutch mechanism 8. At this time, the feed means of the carrier 7 is constituted so as to be divided into the shaking arm 4 and a traverse mechanism 9 and, especially, the greater part of the movable parts of the traverse mechanism 9 is arranged on the lateral side of the cleaning tank 2 to reduce the movable parts arranged directly above the cleaning tank as few as possible.
