Abstract
The disclosure generally relates to a keyboard and, more particularly, to a silent keyboard. A first pressing portion is formed of two strengthening strip elements intersected with each other, and utilized to enhance the rigidity and stability of four guiding pillars. Two grooves are formed on the inner walls of a first frame. Two hooks positioned in opposing sides and two silencing strip elements positioned in opposing sides are formed on the underside of a first key cap and extend outward from the first key cap. The two hooks respectively engage with the two grooves, while each hook is arranged to operably slide along a corresponding groove. The two silencing strip elements engage with the inner walls of the first frame, so that a first key structure can slide steadily within the first frame and does not tilt while sliding.
