ABSTRACT:
A keyboard device for a keyboard-based musical instrument comprises a plurality of chassis arranged in a left-to-right direction, and a plurality of keys attached to the plurality of chassis for pivotal movements and arranged in the left-to-right direction. The overall chassis for the keyboard device is divided into a plurality of chassis which can be separately manufactured, so that the size of each chassis can be reduced as compared with a conventional keyboard device for which a single chassis is manufactured. Since this results in a reduction in scale of manufacturing facilities including a mold and a press machine used for manufacturing the chassis, and easier adjustments to the mold in a trial manufacturing stage, a manufacturing cost of the chassis, i.e., a manufacturing cost of the keyboard device can be reduced.
