ABSTRACT:
A lever40is supported by a lever supporting portion41. The lever40is urged by a first spring45and a second spring46. The urging force of the first spring45varies over the entire operational range of the lever40. The second spring46and a third spring47are provided serially through a movable supporting member48. The displacement of the movable supporting member48is restricted by a fixed supporting member FR. If the urging force of the second spring46exceeds the urging force of the third spring47, the restriction on the displacement of the movable supporting member48is removed. Therefore, the present invention provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano.
