摘要： A keyboard lid opening and closing mechanism for a keyboard musical instrument having a simple structure and not requiring a large space for installation thereof. To house a keyboard lid in the folded state inside the keyboard musical instrument, the mechanism is provided with a reverse V-shape forming portion disposed at the place where the undersurface of the keyboard lid passes while moving, a rotation support portion including first connecting groove walls, and a keyboard lid stop portion including second connecting groove walls. Therefore, the structure of the mechanism for opening and closing the keyboard lid is simplified, and a large space for installation of the mechanism is not necessary since these portions include no movable parts.

The striking members are activated by corresponding keys such as in toy piano. The sound members are attached to a pair of elongated elastic seat members by an adhesive agent. The seat members support the sound members and are in turn supported by a pair of supporting members.
