Abstract
A keyboard device capable of suppressing noise that occurs upon release of the key is provided. The key is formed with a protrusion and a hammer is formed with a sliding surface. Moreover, the hammer is provided with contact portions that come into contact with a side surface of the protrusion when the key is pressed to the bottom in a key-pressing direction. Thus, when the key is released, the contact between the side surface of the protrusion and the contact portions prevents the key from rotating before the hammer, thereby preventing the protrusion from departing from the sliding surface and suppressing the generation of noise that occurs when the protrusion falls on (hits) the sliding surface.
