A keyboard frame (1) of a keyboard instrument capable of adjusting spaces between keyboards includes: a support (80) which is protruding to be inserted into a lengthwise groove (3d) formed in a lengthwise unit (3c) of a keyboard (3), and is formed with a width (W2) narrower than a width (W1) of the lengthwise groove (3d); and a guide (90) which is assembled to the support to be vertically movable and be able to be fixed, is formed with a width (W3) corresponding to the width (W1) of the lengthwise groove (3d), guides the vertical movement of the keyboard (3) while being inserted into the lengthwise groove (3d), prevents the horizontal vibration of the keyboard (3), and displaces to the left and right when moving the location of assembly for the support (80) up and down. A space between the keyboard (3) and a neighboring keyboard (3) is controlled by displacing the location of the keyboard (3) to which the guide (90) is inserted changes left and right when displacing the location of the guide (90) by moving the assembly location of the guide (90) for the support (80) up and down. |
