A locking piece is provided protruding from the side of the hanging piece provided on the front part of the keyboard lid, and a locking piece is provided protruding from the 1F1 part of the hanging piece of the keyboard lid that descends from the side plate side of the front part of the keyboard instrument body. Since a shock absorber is provided that elastically engages with the stopper piece and buffers the impact of the hanging piece on the lower mouth bar, when the lid is lowered to close the keyboard lid, there is no impact on the side of the hanging piece. The MIJ body absorbs and attenuates the downward force of the keyboard cover, and buffers the impact when it hits the lower part of the hanging piece or the lower mouth bar, so that the MIJ body absorbs and attenuates the downward force of the keyboard cover. Even if you forcefully close the keyboard lid, the impact on the bottom bar will be cushioned, preventing damage to the keyboard lid, etc., and also preventing injury if your hands or fingers get caught. I can do it. Furthermore, since the structure is simple, it is easy to manufacture, easy to maintain, and can be provided at low cost.
