た鍵盤装置。 In a keyboard device having a key disposed on a keyboard chassis and a hammer interlocking with the key, an opening with the same circular cross-sectional shape and smaller than the diameter of the circle at the rear is provided at the pivot point at the rear of the key. A bracket forming a shaft with a substantially oval cross-sectional shape is inserted and fitted into a key provided with a groove to hold it, and is attached to the top surface of the chassis, and the key and groove are provided in the hammer rotation fulcrum part, and the bracket is approximately oval-shaped in cross-section. The shaft is inserted into and fitted into a shaft block formed of a plurality of shafts, and is attached to the bottom surface of the chassis, and the lower part of the key and the point of action of the hammer are brought into sliding contact, and when the key is pressed, the hammer is rotated in the anti-gravity direction. A keyboard device characterized by providing a key return force only by the action of gravity.
