Abstract: The flow rate control device includes a main plate corresponding to an inner diameter and including a through hole which is formed at the center thereof and through which a fluid flows, a sub-plate corresponding to a size of the through hole, disposed in front of the main plate, and applied with a pressure of the flowing fluid, and an expansion and contraction flow path formed to connect the through hole and a circumference of the sub-plate to each other and expanded and contracted by the pressure applied to the sub-plate. The expansion and contraction flow path includes a plurality of holes which are formed in a side surface thereof and through which the flow flows, and has a cross-sectional area changed by the pressure to control a flow rate.
