PURPOSE: A compression screw for a juicer composed of compression screw threads and parallel screw threads is provided to promote efficiency of juicing process and get well processed juice products. CONSTITUTION: The screw comprises a main body(100), a couple of compression screw threads(10) winding the main body over and one or more of parallel screw threads (20) going round the body. One of the compression screw threads is separated from the starting point of the other screw thread at a fixed interval. The parallel screw threads has a little lower thread than the compression screw thread at the intersection of the compression thread and the parallel thread and the compression screw thread is proceeded downward with having a little higher thread than the parallel thread or same height with the parallel thread after the intersection. Compressing and sending slants (50) having a fixed size are formed from the acute angle parts of the intersecting points to the surface of the main body to the opposite direction with a crushed material removing direction of the screws. The main body and the compression screw threads are included in a juicing room(150) of the juicer.
