<p>The present invention relates to a juicer in which: a driving shaft hole having a driving shaft inserted therein is formed on the lower part of a rotary brush, which is mounted between an inner wall of a housing and an outer wall of a net drum and has opened upper and lower surfaces and has a net brush for brushing the outer wall of the net drum, so that the driving shaft hole is rotationally mounted on a body; and a screw is arranged inside the net drum and has a screw spiral formed on the outer surface thereof, wherein a screw coupling protrusion or a screw coupling groove is formed on the upper part of the screw and a rotary brush coupling groove or a rotary brush coupling protrusion is formed on the upper part of the rotary brush such that the screw coupling protrusion and the rotary brush coupling groove are coupled or the screw coupling groove and the rotary brush coupling protrusion are coupled in such a manner that the rotary brush is directly rotated by the screw during the rotation of the screw, thereby reducing a failure rate caused by damage to or wearing down of components such as gears and the like and providing a simple and easy assembling operation.</p> |
