Abstract
A keyboard device for a keyboard instrument, including a key support mechanism assembled to a keyboard chassis, improved not only in the ease of assembly during manufacturing of the keyboard device but also in the ease of disassembly during maintenance of the same. The keyboard device includes a keyboard chassis, a key disposed on the keyboard chassis, and a key support mechanism which supports the key from below and causes, upon depression of the key, the depressed key to operate such that the key pivotally moves about a virtual pivot. The key support mechanism includes a first arm and a second arm which, when mounted on the keyboard chassis during assembly of the keyboard device, in a state where one of the arms is pivotally engaged with the keyboard chassis, the other can be mounted on the keyboard chassis while being connected to the one.
