SOLUTION: One end of a plunger 111 of a solenoid unit 110 is connected to a first wire 90 attracted leftward when a sostenuto pedal is treaded down by a player. The other end of this plunger 111 is connected to a second wire 21. A sostenuto rod is connected to the second wire 121. When the sostenuto pedal is treaded down by the player, the plunger 111 and the second wire 121 are moved, leftward by being attracted to the first wire 90 to acturate the sostenuto rod. When, however, the plunger 111 is moved leftward at the time of automatic playing, the relative movement of the first wire 90 and the plunger 111 is so allowed that the second wire 121 moves leftward but the first wire 90 does not move.</p> |
