<P>PROBLEM TO BE SOLVED: To enhance assemblability of a plate-like member to a casing, to enhance allowances to an actual dimension dispersion and a deformation of the plate-like member, and to enhance a sound effect of the casing. <P>SOLUTION: The casing structure for a grand piano type electronic piano 1 is constituted to engage a rear end side 30a of an intermediate plate 30 with an engagement part 21 provided on an inner face 12a of a rear side plate 12, by slide-moving the intermediate plate 30 arranged in a front side of a storage part 20, when attaching the intermediate plate 30 to the storage part 20 surrounded by sideway plates 11, 11 and the rear side plate 12 provided in a body part 10, and to fix, under this state, a fixing piece 37 provided in an underface 34 of the intermediate plate 30 tightly to a piece 15 to be fixed provided in a storage part 20 side, by bolts 16. Attachability of the intermediate plate 30 is enhanced since a fastening portions of the bolts 16 are remarkably reduced. An appearance design of the electronic piano 1 gets excellent since no bolt 16 for fixing the intermediate plate 30 appears in an appearance. <P>COPYRIGHT: (C)2010,JPO&INPIT |
