Abstract:
A keyboard device for an electronic keyboard instrument, making uniform an upper surface height of the rear end of each key in contact with a hammer in a key-released state. The keyboard device includes longitudinally extending wooden keys capable of swinging and laterally juxtaposed, a hammer support disposed rearward of the keys, longitudinally extending hammers having a rear end thereof supported by the hammer support vertically pivotally movably and a protrusion protruding downward from a lower surface thereof for contact with a rear end of an associated key, and hammer contact height-regulating parts each made of a synthetic resin and mounted on the rear end of each key, the part being in contact with the protrusion in the key-released state, to regulate a contact height of the protrusion to a predetermined height.

Claim (Index 11):
A hammer device for an electronic keyboard instrument including a key extending in a front-rear direction and configured to be capable of swinging about a portion close to a center thereof, wherein the hammer device includes a hammer which is placed on a rear end of the key and pivotally moves by being pushed up by the key when the key is depressed, the hammer device comprising:\n a hammer support disposed rearward of the key; a hammer body made of a synthetic resin, which extends in the front-rear direction and has an engaging part of a rear end thereof being engaged with the hammer support, thereby being supported thereon pivotally movably in a vertical direction; a key contact part provided on the hammer body at a predetermined location forward of the engaging part such that the key contact part protrudes downward, the key contact part being in contact with the rear end of the key from above in a key-released state; and a lubricant-blocking portion provided in a side surface of the hammer body so as to prevent a lubricant applied to the engaging part from spilling out to the key contact part.
