Abstract
The present invention provides a peg for stringed instruments, which can reduce rotational errors of a worm gear due to a backlash caused during tuning of a string as low as possible. The peg is also possible to reduce the friction at each rotational portion, to prevent it from seizing up, to greatly reduce a work time required for wiping off a fluid lubricant, and to retain a stable performance for a long time. In the present invention, the peg for stringed instruments comprises a worm rotatable in accordance with rotation of a knob; and a worm wheel mated with the worm and communicated with a string attachment. A solid lubricating material layer is formed on a surface of at least one of the worm and the worm wheel as well as on a worm rod of the worm.
