<p>PURPOSE: To provide a backpost coupling structure and coupling method of a keyboard musical instrument capable of easily making a coupling operation without requiring intricate working of high accuracy. CONSTITUTION: The coupling member 6 itself is coupled to a tone unit 4 from a backpost 2 side by a wood screws 14, there is no need for forming holes to allow the wood screws to arrive at the backpost 2 from the opposite side. Further, the coupling member 6 is merely fixed by screwing the wood screws 14 from the coupling member 6 side to the prescribed position of the unit 4 and, therefore, there is no need for forming a tenon, etc., to the unit 4 and positioning the coupling member 6 in a manner as to prevent the deviation thereof. There is, therefore, no need for executing the intricate working of high accuracy. The coupling of the coupling member 6 to the unit 4 is possible by the screwing operation of the wood screws 14 from the backpost 2 side and further, the coupling of the backpost 2 to the coupling member 6 involves mere fixing of the front end of the backpost 2 to the coupling member 6 by means of a bolt 20 and, therefore, the coupling operation suffices with the operation of only the one side of the unit 4 and the assembly operation is efficient.</p> |
