Abstract
A link mechanism detachably supporting a key top against a back sheet provides a first link member; one end side of the first link member is rotatably held at the obverse surface of the back plate, and the other end side is slidably held at the reverse surface of the key top. A second link member is rotatably connected to the first link member. One end side of the second link member engages rotatably with a rotation support part provided to the reverse surface of the key top and the other end side of the second link member is slidably held at the obverse surface of the back plate. A recess is provided to the second link member, and a protrusion is formed on the rotation support part. The protrusion engages with the recess and restricts detachment of the key top from the second link member.
