ABSTRACT:
A keyboard instrument (e.g., an electronic piano) has a keyboard including numerous actions interlocked with numerous keys arranged on a keybed, and at least one pedal (e.g., damper pedal) arranged on a base board of a housing thereof, wherein it is equipped with a pedal link mechanism including a pedal lever. A keybed reinforcing member is attached to the lower surface of the keybed and is arranged to pivotally support the pedal lever thereunder, wherein a plurality of tapered spacers are put into the space between the keybed and the keybed reinforcing member, which are thus integrally fixed together using screws. One end of the pedal lever is interconnected with the pedal via a hanging bolt, and the other end is interconnected with a vertical link interlocked with at least one action.
