A lever is supported by a lever supporting portion. The lever is urged by a first spring and a second spring. The urging force of the first spring varies over the entire operational range of the lever. The second spring and a third spring are provided serially through a movable supporting member. The displacement of the movable supporting member is restricted by a fixed supporting member. If the urging force of the second spring exceeds the urging force of the third spring, the restriction on the displacement of the movable supporting member is removed. Therefore, the present configuration provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano.
