<P>PROBLEM TO BE SOLVED: To provide a keyboard device of an electronic keyboard instrument, having improved assemblability and disassemblability, while ensuring stable pivotal motion of a key. <P>SOLUTION: The keyboard device includes: a plurality of keys 3, each of which extends in a front-rear direction and has a pivot shaft 23 extending at a rear end in a left-right direction; a keyboard chassis 2 provided for each key, which includes a mounting portion 32 and a plurality of key-separating support portions 35, each for supporting the pivot shaft 23; a pivot shaft bearing member 33 having a pivot shaft support portion 42 cooperating with each key-separating support portion 35 to form a bearing for the pivot shaft 23, to support each key 3 so as to be pivotally moved, and being removably mounted on the mounting portion 32. In assembly of the keyboard device 1, while each key 3 is engaged with the key-separating support portion 35 via the pivot shaft 23 and held on the keyboard chassis 2, the mounting portion 32 faces outward when the pivot shaft bearing member 33 is mounted, and the pivot shaft bearing member 33 can be mounted from above or rear. <P>COPYRIGHT: (C)2011,JPO&INPIT |
