<p>PROBLEM TO BE SOLVED: To provide a balancing pin for keyboard with which work to bring a slip metal fitting into contact with a shelf board and the height control of a key can easily be carried out. SOLUTION: The balancing pin 1 for keyboard consists of a rod part 2, a male screw part 4 provided at the lower part of the balancing pin 1 for keyboard, a striker plate part 6 provided between the rod part 2 and the male screw part 4, and a slip metal fitting part 8 provided at the lower part of the male screw part 4. The male screw part 4 is screwed into the inside 14 of reed, the slip fitting metal part 8 abuts on the shelf board 13, and then the balancing pin 1 for keyboard supports a reed 12. Even when the reed 12 and the inside 14 of reed are expanded or deformed due to absorbed moisture, a key 18 can be adjusted to a position at the time when a piano is initially manufactured only by adjusting this balancing pin 1 for keyboard by rotating the rod part 2 so that the slip metal fitting part 8 abuts on the shelf board 13.</p> |
