<P>PROBLEM TO BE SOLVED: To provide a keyboard lid structure of a keyboard instrument, correcting a deformed keyboard lid to its initial shape even when the keyboard lid is bent and deformed. <P>SOLUTION: The keyboard lid structure includes a deformation correcting member 18, which is pressed to the back of an instrument body 1 with the keyboard lid 10 opened, thereby bending and deforming the keyboard lid 10 in the direction of separating from the instrument body 1. Accordingly, in closing the keyboard lid 10 to cover a keyboard part 8, even if the keyboard lid 10 is bent and deformed by its dead load, when the keyboard lid 10 is opened to press the deformation correcting member 18 to the back of an instrument body 1, the keyboard lid 10 can be bent and deformed in the direction of separating from the instrument body 1 by the deformation correcting member 18. Thus, even if the keyboard lid 10 is bent and deformed, the deformed keyboard lid 10 can be corrected to its initial shape. <P>COPYRIGHT: (C)2011,JPO&INPIT |
