<p>PROBLEM TO BE SOLVED: To provide a leg bracket of a piano which has superior in strength and can drastically reduce the manufacturing cost by the curtailment of material costs and the man-hours, from manufacturing to mounting. SOLUTION: A bracket body 1 of the leg bracket A of the piano GP, for mounting a piano body B with the lag L, is composed of a casting integrally cast with plural mounting holes 2 for mounting, by which the need for external form machining to the bracket body and perforation of plural mounting holes for mounting screws, etc., is eliminated, so that man-hours can be reduced. By making bracket through casting, the material cost can be made lower than that in the conventional materials.</p> |
