摘要： The disclosure provides a keyboard device and an electronic musical instrument. The keyboard device includes: a plurality of keys 60 arranged in a left-right direction (scale direction); a base member 50 supporting the keys 60; a vibration transmission member 70 being in contact with the base member 50 across an arrangement region of the keys 60 in the left-right direction; and a vibrator 72 fixed to the vibration transmission member 70 and vibrating based on pressing of the key 60. Therefore, the vibration of the vibrator 72 is transmitted to each of the keys 60 (base member 50) arranged on the left and right via the vibration transmission member 70. As the vibration transmission member 70 has higher rigidity than the base member 50 made of resin, the vibration of the vibrator 72 is easily transmitted in the left-right direction through the vibration transmission member 70.

摘要： A keyboard device is provided including a chassis; a mass body which is turnably installed in the chassis; and transmission means which transmits a driving force in response to key touching of a key to the mass body, wherein the mass body includes an inner wheel and an outer wheel installed on a radially outward side of the inner wheel and is configured to serve as a component for transmitting a torque in one-way direction between the inner wheel and the outer wheel. The transmission means is engaged with one of the inner wheel and the outer wheel of the mass body. The torque is transmitted between the inner wheel and the outer wheel of the mass body at a time of key touching. The torque is not transmitted between the inner wheel and the outer wheel of the mass body at a time of key release.
