An electronic percussion instrument pedal device uses a spring structure in a space between a bottom structure and a foot pedal board structure to regulate the movement of the foot pedal board structure. Even when the foot pedal board structure is not being moved, it is regulated by the above mentioned spring structure into a proper near horizontal position. If the foot board is stepped on, the coil spring will stretch and a load (stability) will become strong. As a result, when the foot board is in a position near the position in which it is not stepped on, the load is initially relatively light and then becomes heavier as the user continues to further step on the foot board. This is approximated to the action of an acoustic bass drum, and a good actuation feeling.
