Abstract

A key top is urged upward via a rubber elastic member stretched between a first link member and a second link member with ends of shaft members provided to both side portions of a shaft of the first link member and shaft members provided to both side portions of a shaft of the second link member supported in insertion holes in thick portions of each rubber elastic member in one embodiment. Alternative embodiments use a ring or retangular type rubber elastic member that encloses a base position of the first and second link members. <IMAGE>
