Abstract
A keyboard device for a keyboard instrument capable of having each key easily mounted on a keyboard chassis while ensuring stable pivotal motion of the key, without damaging the key. A keyboard chassis holds keys in arrangement in a left-right direction. A key support part has a lower support portion for supporting a pivot shaft of a key from below, and left and right upper support portions erected with a predetermined spacing in the direction, for supporting a key rear end portion located upward of the shaft from above. When mounting the key to the key support part, the upper support portions have its spacing expanded by the key rear end, thereby being elastically deformed to pass the key rear end, and thereafter, elastically return to their original state to hold the key rear end in a retained state by cooperating with the lower support portion.
