In order to provide a keyboard device in which a pad used as a palmrest can be stored in the main body, a lock member and an operating segment are integrally formed by a resin resilient member. An engaging segment is formed at the extremity end of a resilient piece constituting a part of the resilient member, the engaging segment is inserted into an engaging hole formed at the pad and it is locked with the pad stored in a notch. Releasing of the locked state is performed such that the resilient member is resiliently deformed while the operating segment is pressed and then the engaged state between the engaging segment and the engaging hole is released. As a locked state releasing means, the resilient piece is provided with a small projecting piece, the main body is provided with a small protrusion, the engaging segment is resiliently deformed in a direction moving away from the engaging hole against the resilient piece by movement of the small projecting piece and the small protrusion while they are being abutted to each other.
