Abstract
A stopper rail of a silent piano, which can make collision noise generated when a hammer shank collides against the stopper rail, blurred in the sense of pitch thereof and difficult to be recognized by the human ear, in a silent performance mode. In this mode, the stopper rail is contacted by the hammer shank of a hammer being pivotally moved to stop pivotal movement of the hammer. The stopper rail includes a rail body having a predetermined flexural rigidity allowing vibration, a first cushion provided on one surface of the hammer shank, for being contacted by the hammer shank being pivotally moved, and a vibration suppressing portion provided on an opposite surface of: the rail body to the first surface so as to apply a load to the rail body to suppress vibration of the rail body when the hammer shank contacts the rail body.
