の鍵装置。 In a key device for an electronic piano that is equipped with a let-off element and is configured to provide the let-off feeling of touching a piano key by deforming the let-off device when a key is pressed down, the let-off element is seated with a bowl-shaped elastic body reversed. It has an air vent hole in a chamber formed by being attached to the plate and formed by the elastic body and the seat plate, and the air vent hole has an air vent hole in which the speed at which the let-off element returns to its original shape when the key is returned is equal to the return speed of the key. A key device for an electronic piano characterized by being sized so as to be slower than the previous key device.
