Abstract
A keyboard device includes a base plate, a connecting element and a keycap. The connecting element is connected with a hook of the keycap and the base plate. The keycap includes an elastic structure, a first hooking part and a second hooking part. The elastic structure hook is installed on an inner surface of the keycap. The first hooking part is arranged beside a first side of the elastic structure. The second hooking part is arranged beside a second side of the elastic structure. While the connecting element is assembled with the keycap, the first hooking part and the second hooking part are pushed by the connecting element and the keycap is bent in response to the elasticity of the elastic structure. Consequently, the first hooking part is moved away from the second hooking part.
