<p>PURPOSE:To set the tuning pins of strings corresponding to respective pitches or the string length at a frame pin part by providing a string bearing crest which is protrusively formed integrally to a frame and whose ridge line is set in the direction where strings array. CONSTITUTION:A string bearing crest 15 is integrally and protrusively formed to the top face part of a frame 11. Arrangement is so made that strings 16 are supported on the ridgeline formed by the sectional arc of this storing bearing crest 15. A step part 17 which is made lower than the ridgeline of the string bearing crest 15 is protrusively formed and a plurality of recessed parts 18 extending in the direction where the strings 16 array are formed in this step part 17. Here, a string retainer 19 is directly screwed and fixed to the step part 17 of the construction integral with the frame 11. Hence, this string retainer 19 becomes the structure integral with the frame 11 and therefore it becomes a sufficiently robust and stable structure, due to which the boundary conditions for the strings 16 are extremely definitely set and this is surely held over a long period of time.</p> |
