Abstract
A keyboard device includes plural key structures. Each key structure includes a plate assembly, a keycap, a connecting member and a buffering element. The plate assembly has a hollow region. The keycap is located over the plate assembly. The connecting member is connected between the keycap and the plate assembly. The keycap is connected with the connecting member through at least one hook of the keycap. The keycap is movable upwardly or downwardly relative to the plate assembly through the connecting member. The buffering element is installed on the plate assembly. The buffering element is extended in a direction toward the keycap and penetrated through the hollow region of the plate assembly. While the keycap is moved downwardly and the at least one hook of the keycap is contacted with the buffering element, there is the gap between the keycap and the plate assembly.
