PURPOSE: A filter structural body for dust collector is provided to easily attach and detach the venture to the top cap and enhance the flux of the air which passes through the venturi by improving the internal structure of venturi. CONSTITUTION: A filter structural body for dust collector comprises a top cap (220), a bottom cap (240), and a connector (250). Venturi is mounted on the top of the top cap. Several top cap void sections (222) are formed on the top cap as a unit at regular intervals, and a connector inserting hole (224) which hole is inserted with the combination of venturi mounting groove (226) and connector to the top cap. Venturi comprises a venturi combining unit (238) protruded and extended in an outside direction on one side of the lower part of the outer circumference body (231) of the structure which top and bottom is opened and circumference of side is blocked. A venture combining unit is inserted and connected to the constant space of the inside of the venture mounting groove in an insert method.
