PURPOSE: A foreign matter removing apparatus of a cylinder for an injection machine, which removes gas and moisture from molten resin, is provided to remove foreign material by turning molten resin at a mixing part after zigzag moving at a cylinder. CONSTITUTION: A foreign matter removing apparatus of a cylinder for an injection machine comprises first and second vent ring gears(3,4) and a backend poppet gear(7). Molten resin, supplied to a cylinder(110), zigzag moves along a resin injection passage between tooth profile A and B(32,42). The molten resin is overturned in a mixing part to discharge the moisture and gas of the molten resin through the scratches of first and second vent ring gear. The moisture and gas are collected inside a gear connection shaft(1).
