Abstract

PURPOSE: To ensure the connection of sufficient string vibrations at high and next high sound regions by attaching a separate string receiver to a frame body such that its position can be adjusted in the vertical direction and in the tensile direction of the string.
CONSTITUTION: The portion to provide connection between a string receiver 1 and a rib 3 formed to project from a frame body is formed with C-shaped recesses 11 and 12, and the latter recess 12 is made to have a larger length l1 in the direction of the rib 3 than the width l2 of the string receiving portion 1 so that the string receiving portion is made slidable in the longitudinal direction of the rib. The engaging portion between the string receiving portion 1 and the rib 3 is formed with an idle hole 13, and the rib 3 is formed with a threaded hole 14 at a corresponding position. In case the rib is mounted to the string receiving portion, a spacer 15 is placed on the hole 14, and the lower side 11a of the recess 11 and the bottom 12a of the recess 12 are arranged to face and placed in a crossing shape upon the portion 1 and the rib 3. Then, a bolt 16 or the like is screwed through the hole 13 into the hole 14. Incidentally, the radius of curvature of the section of a string receiving element 5 is made gradually smaller from the next high tone to the highest tone.
