<p>PROBLEM TO BE SOLVED: To provide a bridge pin of a piano which allows the secure mounting of the bridge pin to a bridge with decreased variations in the degree of tightening and allows the suppression of the loosening with lapse of time and the consequent improvement in the sound quality of the piano. SOLUTION: The bridge pin 1 of the piano mounted at the bridge 7 in order to detain a string 2 to the bridge 7 integrally has a threaded part 1a which is screwed to the bridge 7 and a string detaining part 1b which is continuous with this threaded part 1a, projects outward from the bridge 7 and detains the string 2. A screw 1c for enhancing the adhesion degree to the bridge 7 is formed on the surface of the threaded part 1a.</p> |
