A fastening device for an electronic board comprises a base unit, a position shaft and a resilience device wherein the base unit has a first opening, a second opening and a sidewall used to connect the first opening and the second opening. The surface region of base unit adjacent to the first opening has a plurality of protrusions and the sidewall essentially includes a plurality of extension portions for tightly withstanding the electronic board by resilience inducing from the extension portion. The position shaft has a first flange having a smaller size than that of first opening to pass through the first opening and a second flange having a larger size than that of first opening to lean against the inner surface region of first opening. The resilient device, coupled to the position shaft and inside the sidewall, automatically aligns the locating holes of the electronic board.
