Summary:PROBLEM TO BE SOLVED: To achieve a touch feeling close to that of an acoustic piano with a structure different from the structure of the acoustic piano.SOLUTION: A keyboard device in one embodiment of the present invention comprises: keys; a frame; flexible parts for rotating the keys with respect to the frame, the flexible parts each having the longitudinal direction and having, on a cross section orthogonal to the longitudinal direction of the flexible part, an area in which the length in a first direction orthogonal to a scale direction is continuously increased toward an end; and support parts each supporting the flexible part at a portion closer to the end than the area and having a concave part arranged on a side along the scale direction.SELECTED DRAWING: Figure 10 【課題】アコースティックピアノの構造とは異なる構造によってアコースティックピアノに近いタッチ感を実現すること。【解決手段】本発明の一実施形態における鍵盤装置は、鍵と、フレームと、フレームに対して鍵を回動させるための可撓部であって、長手方向を有し、可撓部の長手方向に直交する断面において、スケール方向に直交する第１方向の長さが端部に近づくほど連続的に増加する領域を有する可撓部と、可撓部の領域より端部側を支持し、スケール方向に沿った側に凹部が配置された支持部と、を有する。【選択図】図１０
