<P>PROBLEM TO BE SOLVED: To provide a keyboard device of a keyboard instrument, which can prevent a key from laterally deflect when depressed and released, to be able to ensure stable turning of the key. <P>SOLUTION: The keyboard device includes a keyboard chassis 2, a plurality of keys 5 freely turnably supported by the keyboard chassis 2, and a key stopper 24 for restricting upper limit positions of the plurality of keys 5. A prescribed key 4 out of the plurality of keys 5 includes: a key body 4a which extends in a longitudinal direction and has a rear end part freely turnably supported by the keyboard chassis 2; and an upper limit position restricting projection 4c which is provided under a front end part of the key body 4a integrally with the key body 4a in a state of projecting forward of a front surface of the key body 4a and, when the key is released, is brought into contact with the key stopper 24 from below to restrict the upper limit position of the key 4. Furthermore, a key guide 25 is provided which is provided on the keyboard chassis 2 correspondingly to the prescribed key 4 and guides the upper limit restricting projection 4c in a vertical direction in a horizontally immobile state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
