特徴とする電子楽器の鍵装置。 A U-shaped spring is fixed to either the key or the main body of the instrument, and a sliding contact member is fixed to the other side, and both opposing pieces of the spring slide into opposing surfaces when the key is pressed down, and the sliding contact is made. A protrusion is formed on at least one of the facing surfaces of the member, and friction is generated by sliding contact of the spring with the sliding member, and the friction is maximized when the spring rides over the protrusion. Key device for electronic musical instruments.
