Abstract

See full text

A key top includes a body part having a first width and a flange formed on a lower end portion of the body part so as to have a second width which is larger than the first width. A click rubber is provided on a bottom face of the body part of the key top. The click rubber is elastically deformable such that the key top is vertically moved between an upper first position and a lower second position. A case is formed with a first chamber and a second chamber. The first chamber has a third width which is larger than the first width but smaller than the second width, for accommodating the body part of the key top therein. The second chamber is continued from the first chamber and has a fourth width which is larger than the second width, for accommodating the flange of the key top and the click rubber therein.
