Abstract
There is disclosed a damper for a grand piano, which is simple in construction and can be manufactured at reduced costs by reducing the number of components, the number of assembling steps, and the number of adjustment operations. A damper for a grand piano moves out of contact with strings in a manner interlocked with operation of a damper pedal, to thereby create a damper pedal effect. A plurality of damper levers each have a rear end portion thereof pivotally mounted to the damper rail and each extend forward. Each damper head is connected to the upper side of a corresponding one of the plurality of damper levers and brought out of contact with a corresponding one of the strings as the corresponding damper lever moves upward. A lifting rail is arranged below the plurality of damper levers, for pivotally moving the plurality of damper levers upward simultaneously by being pushed upward when the damper pedal is operated. The damper lever rail and the lifting rail are formed by a molded component as a unitary member and arranged in a pivotally movable manner.
