ユエータ。[Scope of Claim for Utility Model Registration] An actuator for a player piano in which a plurality of electromagnetic plungers are arranged corresponding to each key, and the plungers are actuated by energizing to operate the corresponding key. A common yoke that is bent in a U-shape and extends commonly to a plurality of keys is disposed below the rear end of the key so as to face substantially parallel to the lower surface of the key. The electromagnetic plungers are arranged in a staggered manner, and the push-up buttons of each plunger are projected above the common yoke, so that the top end surfaces of the push-up buttons are closely opposed to each other in parallel with the lower surface of the key, and the push-up buttons of the electromagnetic plungers in the front row are pushed up. An actuator for a player piano, characterized in that the stroke of the button is smaller than the stroke of the push-up button of the electromagnetic plunger group in the rear row.
