PROBLEM TO BE SOLVED: To provide a keyboard lid opening/closing device capable of downsizing the whole musical instrument by enabling formation of a housing space of a keyboard lid compactly.SOLUTION: A keyboard lid opening/closing device includes: a guide part 12 for guiding a keyboard lid 9 from a position at which the keyboard lid 9 sliding with respect to a musical instrument case 1 covers and closes a keyboard part 7 in the musical instrument case 1 to a position at which the keyboard lid 9 is moved into the musical instrument part 1 to expose the keyboard part 7; and a guide slidable connection member 15 for connecting the keyboard lid 9 and the guide part 12 in a freely slidable manner. Thus, when the guide part 12 guides the keyboard lid 9 to move it, the guide slidable connection member 15 relatively slides the keyboard lid 9 with respect to the guide part 12 to be able to make the movement length of the keyboard lid 9 shorter than the length of the keyboard lid 9 in a sliding direction. Thus, the keyboard lid 9 can surely and satisfactorily be housed in the musical instrument case 1, and the keyboard lid 9 can surely and satisfactorily cover the keyboard part 7. |
