【考案の詳細な説明】
本考案はギター等の弦楽器に使用する糸巻き金具に関す
るものである。[Detailed Description of the Invention] The present invention relates to a thread winding metal fitting used in stringed instruments such as guitars.
従来、本体内において互に噛合うウオームとウオームホ
イールを設けた糸巻き金具においては、本体によるウオ

制するために同ウオームの内外両端を本体内壁に直接当
接させたり、内端のみを当接させて外端をウオームと同
径の回動部としたりするのが一般的であった。Conventionally, in a thread winding fitting that has a worm and a worm wheel that mesh with each other in the main body, the main body supports the worm by placing both the inner and outer ends of the worm against the inner wall of the main body in order to restrict the movement of the worm in the axial direction. It was common for the worm to come into direct contact with the worm, or to have only the inner end come into contact with the worm and the outer end to be a rotating part with the same diameter as the worm.
ところが前者の場合には、ウオームの端部はウオームの
歯切り加工の関係で滑らかに形成することが難しいため

とができず、又、後者の場合には同径の膨出部に対し回
動部に相当する部分を除いてウオームの部分にだけ刃切
りを行う必要があってその加工が面倒であり、結局製造
コストの上昇につなか゛るという欠陥があった。However, in the former case, it is difficult to form the end of the worm smoothly due to the gear cutting process of the worm, so when it is assembled into the main body and rotated, it cannot be rotated smoothly. In addition, in the latter case, it is necessary to cut only the worm part, excluding the part corresponding to the rotating part for the bulge part of the same diameter, which is cumbersome to process, resulting in an increase in manufacturing costs. There was a flaw in that it was connected to

巻き金具を提供することにある。The purpose of the present invention is to make the rotating part at the front end of the worm smaller in diameter than the worm, and to eliminate the defects existing in the prior art by interposing sliding rings at both ends of the worm.
To provide a thread winding metal fitting for a stringed instrument, which allows a worm to be easily cut, an adjustment knob can be rotated lightly, and tuning can be performed accurately and easily by preventing rattling.

い考案である。As described in detail above, the present invention has a housing member 1 with one side open and a worm wheel 3 provided therein, and a large diameter bulge 7 within the main body 18, which is made up of a cover 17 that covers the open side. A worm shaft 5 with a worm 8 meshing with the worm wheel 3 is inserted, and a worm shaft 5 is inserted at both ends of the worm 8 to prevent play of the worm 8 in the axial direction of the worm shaft 5 and to allow the worm 8 to rotate easily. Gear cutting of the worm 8 is facilitated by interposing a sliding ring 10.13 having an axial distance maintaining function and sliding properties to prevent the worm 8 from coming into direct contact with other members. Not only can this reduce manufacturing costs, but the adjustment knob can be turned easily, preventing wobbling and making tuning work accurate and easy. This is a practical idea as a metal fitting.
