Abstract
A lid structure of a keyboard instrument is provided, which improves a design degree of freedom of an instrument body. When a covered keyboard is changed from a close state to an open state, a front lid rotates relative to a back lid through a rotation shaft. A front guide slot and a rack built in the instrument body are used to guide backward movements of an engagement pin and a pinion. Since the rack is located posterior to the front guide slot, the back lid approximately maintains a pose to move backwards. A height of an accommodating space of the instrument body set to the open state is only required to be equal to a thickness of the back lid. Therefore, the accommodating space is reduced, an overall height of the instrument body is suppressed and a design degree of freedom of the instrument body is improved.
