Abstract
A tuning peg for stringed instruments having a core shaft which is rotated as a string spool shaft by a manually-operated knob and an outer sleeve which is externally mounted on the core shaft. The top surface of the core shaft is formed as a string receiving surface and at least the lower part of the core shaft is formed as a threaded pulling part. At least the lower part of the outer sleeve is made as an internal thread part which engages with the threaded pulling of the core shaft and the trunk part of the outer sleeve is provided with a string passing hole which is open in the orthogonal direction to the axis of the outer sleeve and the ceiling surface of the string passing hole inside the outer sleeve is formed as a string pushing surface. When a string is passed through the string passing hole and the knob is rotated, the outer sleeve lowers and the string pushing surface pushes the string onto the string receiving surface.
