Abstract
A key structure of a keyboard includes a base plate, a keycap, and an elastic body sandwiched between the base plate and the keycap. The elastic body has a neck portion. One end of the neck portion is provided with a bowl-shaped support toward the base plate, and the other end of the neck portion extends toward the keycap to form a flange. The outer peripheral dimension of the flange is larger than that of the outer peripheral dimension of the neck portion. With the flange being sandwiched between the keycap and the neck portion, the flange can exert an even force to the neck portion even through the keycap is subjected to an uneven external force, thereby preventing the neck portion from inclining or swaying. Thus, the convenience in using the keyboard and the stability during its operation can be improved greatly.
