摘要： PROBLEM TO BE SOLVED: To provide a pedal device of an electronic musical instrument which attains a similar characteristic with a reaction characteristic of a pedal of a grand piano, in a simple structure.SOLUTION: A lever 1 of which fulcrum 1c is supported by a lever support part 2b, is rocked in a predetermined range of a stroke by player's stamping operation to a lever operation part 1a. A coil spring 4 is displaced in a whole range of the stroke of the lever 1, and a reaction force with a characteristic which increases as the displacement increases is generated. A dome-shaped rubber member 5 starts displacement from the middle of the stroke of the lever 1, and a change rate of the reaction to the displacement generates reaction of a characteristic which decreases in the middle of the displacement without becoming a negative value. The characteristic is obtained by connecting the dome-shaped rubber member 5 to the lever 1 from the middle of the stroke of the lever 1, and starting displacement by further stamping operation of the lever 1, to generate a buckling from the middle of the displacement.
