ABSTRACT:
A pedal keyboard for an electronic musical instrument, includes a pedal key vertically pivotal about a pivot mechanism mounted on a frame of a housing for the electronic musical instrument, a spring for biasing the pedal key so as to cause the pedal key to return to an initial position, and a stopper for limiting pivotal movement of the pedal key. The spring is arranged behind the pivot mechanism of the pedal key, and the stopper is arranged behind the spring, thereby improving key depression feeling and forming a gap in the pivot mechanism to achieve smooth pivotal movement of the key.
