Abstract:
    A string-striking device of a piano by which static loading applied to a front end of a key on the playing side can be readily adjusted. Each key ( 3 ) is provided with a long weight lever ( 21 ) disposed along the length direction of the key 3 at an upper part of the key ( 3 ) on the side opposite of the key to the playing side. The weight lever ( 21 ) is arranged such that one end thereof is fixed to a piano body so as to allow the weight lever ( 31 ) to freely swing up and down, and the other open end, which can be vertically displaced, is brought into contact with the upper surface of the key ( 3 ) and applies its own weight on the key ( 3 ). Thus, the static loading applied to the key ( 3 ) can be adjusted by replacing the weight lever ( 21 ) without disassembling the string-striking device and removing the key ( 3 ).
