PROBLEM TO BE SOLVED: To provide a keyboard device capable of preventing contact sound from being generated between a key unit and an electronic circuit board in keyboard operation and musical sound generation.SOLUTION: A keyboard device 1 is such that a key unit 11 is fixed to an electronic circuit board 3 with a screw 10 as fixing means, the key unit having a black key base, a three-tone white key base, or a four-tone white key base, as a base supporting a black key 5c or white key 6c and 7c and the black key 5c or the white keys 6c and 7c as keys, formed integrally of resin. The four-tone white key base is provided with an engagement part 8 and a projection part 9 as temporary fixing members for temporarily fixing the key unit 11 to the electronic circuit board 3, and once the key unit 11 temporarily fixed to the electronic circuit board 3 with the engagement part 8 and the projection part 9 is primarily fixed to the electronic circuit board 3 with the screw 10, a gap is formed between the engagement part 8 and the projection part 9, and the electronic circuit board 3.SELECTED DRAWING: Figure 5 |
