<p>PROBLEM TO BE SOLVED: To use a secure turnover preventing structure as a support for the back side of the upright piano. SOLUTION: The upright piano 1 is mounted on a floor surface at both floor surface contact parts through soleplates 3 which are longer than the front- rear maximum size of the piano, support metal fittings 6 are provided which has one abutting part that couples the soleplates with the piano and is coupled integrally with the piano to abut on the floor surface and makes the abutting part abut against the floor abut on the floor surface surface behind the line connecting the rear ends of both the soleplates and at the right-left directional intermediate position of the piano. A piano with casters is mounted on the floor surface across soleplates below time casters, the front sides of the soleplates are coupled with the front casters 7, and the rear sides are fixed to the piano back through L-shaped metal fittings 5. The support metal fittings have a main body which is elongated upward successively to the floor abutting part, and the main body is formed in a shelf shape which branches at a lower part and coupled with the lower part of the piano back and also bends at an upper part and is coupled nearby the upper end of the piano back.</p> |
