PROBLEM TO BE SOLVED: To provide a keyboard lid that can be compactly housed to enable the overall size of the musical instrument to be reduced.SOLUTION: A keyboard lid 9 that openably covers a keyboard unit 7 disposed in an instrument case 1 is divided into a front lid part 22 and a rear lid part 23, and the divided front lid part 22 and rear lid part 23 are linked by an extensible linking part 24 to be extensible in the back-and-forth direction of the instrument case 1. Therefore, when the keyboard lid 9 covers the keyboard unit 7, the extensible linking part 24 can extend to increase the total length of the front lid part 22 and the rear lid part 23, or when the keyboard lid 9 uncovers the keyboard unit 7, the extensible linking part 24 can contract to reduce the total length of the front lid part 22 and the rear lid part 23. In this way, the keyboard unit can securely and satisfactorily cover the keyboard lid, and the keyboard lid can be compactly housed. |
