ABSTRACT:
A machine head for guitars is disclosed. In the machine head, the tension of a string is adjusted by sequentially rotating a manually operated adjusting knob, a worm engaging with the knob, a worm wheel engaging with the worm, and a winding peg integrated with the worm wheel with the string wound on or unwound from the winding peg. A cap guider is formed on the top end of the winding peg, while a string holding cap is rotatably fitted over the cap guider of the winding peg, thus being brought into a rotatable engagement with the guider. In an embodiment, the guider has upper and lower guide discs integrated at both ends of an eccentric shaft, while the cap has two string insert holes on its sidewall at eccentric positions. When the winding peg is rotated with a string passing through the two string insert holes, the string is firmly jammed at the junction between the eccentric shaft and the sidewall of the string holding cap. The machine head thus allows a user to easily hold a string to the winding peg without catching the end of the string with the fingers.
