<p>PURPOSE: To provide a device which effectively generate escape effect when, specially, a key of the pipe organ for church is depressed and a structure which holds the keyboard. CONSTITUTION: An element 8 which is essentially spherical and elastic or given elasticity while supported by a keyboard holding device 2 under keys 6 and 7 has its base part positioned above the keyboard holding device 2 and is provided with a collar in order to form its spherical surface by the heat compression of a rubber plate and give constant resistance to the keys, and strain generated by the keys is given over the entire surface of the spherical element 8. Therefore, the upper collar moves in parallel to itself through the operation of the depressed key to spread the whole strain of the rubber element uniformly, thereby providing effective escape effect.</p> |
