PROBLEM TO BE SOLVED: To provide a support assembly capable of reducing variation in touch feeling when operating a key compared to a keyboard device of an acoustic piano while reducing the manufacturing cost for the support assembly.SOLUTION: The support assembly of an embodiment, includes: a support which is disposed rotatably with respect to a support rail; a jack which is rotatably connected to the support at the side opposite to the rotation center of the support; and a support heel which is disposed to the lower face side of the support and comes into contact with the member connected to a key. The support has a bent part for forming a part which is disposed lower than a space, which is formed closer to the jack than at least the support heel in the space between the rotation center of the support and the rotation center of the jack.SELECTED DRAWING: Figure 3 |
