Abstract
A damper for a piano, which has a bifurcated damper felt of which a space between two protrusions is difficult to be narrowed. A damper head extends along three strings in a lengthwise direction thereof and is movable in directions in which the damper moves into and out of contact with the three strings. Damper felt is attached to a string-side surface of the damper head such that it extends in a lengthwise direction of the damper head, and includes two protrusions formed to protrude toward the strings in a bifurcated manner such that they can be brought into contact with the three strings in a state inserted into respective spaces therebetween. The damper felt is attached to the damper head such that deformation of the damper felt in which a space between the two protrusions is narrowed is resisted.
