PURPOSE: A pushing apparatus of cutter blades for use in a crushing machine is provided to allow the respective cutter blades to come into close contact with one another with an elastic compressive force, thereby enabling even very thin materials, such as fabrics or vinyl, to be smoothly crushed. CONSTITUTION: The pushing apparatus of cutter blades comprises a ring shaped pusher plate(11) movably interposed in a slidable manner between a driving rotating shaft(3) and a driven rotating shaft while contacting with the outermost cutter blade and a spacer(6'), a ring shaped pusher(12) having a spring guide pin(12') to be selectively fitted into associated one of guide grooves(11'), an elastic spring(13) elastically installed between the pusher and pusher plate so as to apply elastic lateral movement force to all of the cutter blades and spacers, and a lock nut(14) for adjusting the pushing force of the elastic spring.
