A keyboard device for a keyboard instrument includes a plurality of key support mechanisms each provided in a state engaged with a keyboard chassis and supporting an associated key from below, for causing, upon key depression, the depressed key to operate such that the key pivotally moves about a virtual pivot located rearward of a rear end of the key. Each key support mechanism includes first and second arms each extending a predetermined length in a front-rear direction and configured to be swingable. The first and second arms are pivotally and slidably connected to each other. A rear-side connecting portion of the key includes a connecting body portion and a pair of engagement protrusions, and a rear-side connecting portion of the second arm includes two connecting arm portions having a bifurcated shape and formed with connecting holes.
