A keyboard device for an electronic keyboard musical instrument is provided for permitting a significant reduction in the number of parts constituting a hammer supporting members and the number of assembling steps required therefor, thereby reducing a manufacturing cost, and also for permitting hammers to be mounted in a high mounting accuracy to eliminate noise. The keyboard device comprises a chassis, a hammer rail made of an aluminum extrudate and coupled to the chassis, a plurality of keys pivotably supported by the chassis, a plurality of hammers each provided for each of the plurality of keys, pivotably supported by the hammer rail and configured to pivot in response to depression on a key associated therewith, and a stopper mounted to the hammer rail for restricting a pivotal movement of a hammer caused by depression on a key associated with the hammer.
