A shutter blade structure includes a shutter integrally made into a transparent, semi-transparent, or opaque hollow shape with solid, colored, or patterned decoration designs disposed at the surface thereon. The shutter thereof has an oval-shaped hollow sleeve chamber disposed at the interior therein for two support rods to be oppositely located therein, and a support opening respectively formed at both ends thereof for a retaining cap to be registered therewith so as to neatly expand the full width of the hollow sleeve chamber thereby. The retaining cap is provided with a pair of positioning holes symmetrically disposed at one side thereon for holding in place both ends of the two support rods respectively, precisely stretching out the full length of the shutter thereof. Besides, the retaining cap is also equipped with a coupling section properly protruding at the other side thereon to be mounted to a left/right side frame of a ventilation window, or reversibly located at the hollow sleeve chamber therein for use on a Venetian blind. Thus, the shutter is flexibly fit to both ventilation windows and Venetian blinds, and is capable of being produced on a massive scale, efficiently simplifying the steps of processing so as to reduce the cost of production for achieving the economical efficiency and boosting the competitive power thereof on the market.
