PROBLEM TO BE SOLVED: To provide an angle adjustment tool capable of suppressing manufacturing costs of a keyboard instrument, preventing breakage of a hinge, and also raising functionality, and the keyboard instrument with the angle adjustment tool.SOLUTION: An angle adjustment tool 1 prevents breakage of a hinge since a load is applied to a thick part 10, and power is not applied to the hinge even when a load is applied to a music stand by being provided with the thick part 10. In addition, the angle adjustment tool 1 is easily manufactured by extrusion molding, and a general one-fold hinge is only to be used as a hinge for rotatably attaching the music stand to a top plate. Thus, when a keyboard instrument is manufactured by using the angle adjustment tool 1, its manufacturing costs can be suppressed extremely low in comparison with the case of using two special two-fold hinges. Moreover, when the keyboard instrument is manufactured by using the angle adjustment tool 1, since angle adjustment of the music stand becomes possible, functionality of the keyboard instrument is raised.
