PROBLEM TO BE SOLVED: To reduce manufacturing cost of a support assembly, while suppressing the change in touch feeling during key operation, in a keyboard device.SOLUTION: A support assembly includes: a support 210 disposed to be turned with respect to a frame; a jack supporting part 2105 connected to the support; a jack 250 with a recess 2506 formed at the bottom, which is disposed at the support in a turnable manner when a jack rotary shaft 2110 is arranged inside the recess; and an operation part 2562 that is fixed to the jack and receives downward action. A width L1 near an opening end of the recess is larger than a width L2 of the jack rotary shaft.SELECTED DRAWING: Figure 3A 【課題】鍵盤装置において、鍵の操作時のタッチ感の変化を抑えつつ、サポートアセンブリの製造コストを低減すること。【解決手段】サポートアセンブリは、フレームに対して回動可能に配置されたサポート２１０と、サポートに接続されたジャック支持部２１０５と、下方に凹部２５０６が設けられ、凹部の内側にジャック回転軸２１１０が配置されることでサポートに回動可能に配置されたジャック２５０と、ジャックに固定され、下方への作用を受ける作用部２５６２と、を有する。凹部の開口端部付近の幅Ｌ１は、ジャック回転軸の幅Ｌ２よりも大きい。【選択図】図３Ａ
