Abstract
When a middle plate is to be mounted to an accommodating section surrounded by left and right and rear side plates provided on a body section in a casing structure of a grand-piano type electronic piano, the middle plate positioned in front of the accommodating section is slid rearward, so that a rear end edge portion of the middle plate is fitted into a fitting section provided on the inner surface of the rear side plate and then fixing pieces provided on the underside of the middle plate are fixed to fixation pieces provided on the accommodating section by means of bolts. Such an arrangement can reduce the number of portions to be fixed by bolts and thereby mount the middle plate with an enhanced mounting efficiency. Because the bolts do not appear on the exterior of the electronic piano, the electronic piano can have an enhanced outer appearance design.
