Abstract: A capotasto C includes a clamp 100 and a lever 400. The clamp 100 includes a supporting bar 200 and a string pressing bar 300. The lever 400 is engaged with the supporting bar 200 and with the string pressing bar 300. In a condition in which the clamp 100 has a neck 1 of a guitar between the supporting bar 200 and the string pressing bar 300, when the lever 400 is pushed to the neck 1, the clamp 100 is closed, and a pressing pad 332 of a string pressing part 330 of the clamp 100 presses strings 3 onto a surface 1a of the neck 1. When the lever 400 is pulled out, the clamp 100 is opened by a biasing force of an open spring 120 of the clamp 100, and the capotasto C can be removed from the neck 1.

The bridge has a saddle body 50 that is formed with string grooves 55 at two ends thereof. The string groove 55 has a uniform portion 56 and deep groove portions 57. The deep groove portion 57 is formed into an arc shape in cross section and has a larger curvature radius than that of the uniform portion 56. The uniform portion 56 and the deep groove portion 57 cross with each other at a predetermined portion, and the vicinity of the predetermined portion has a chevron shape in vertical cross section. The chevron shapes of the deep groove portions 57 have peaks P that are arranged at different position in the circumferential direction.

Abstract: An adjuster with a frame attachable to the front end portion of an instrument tailpiece, a lever member with a base portion and a front plate portion swingably supported by the frame, a mounting portion with an adjusting screw positioned therein, an anchoring portion extending from the lever member that projects through an anchor hole to the surface side of the tailpiece to removably anchor a string of the instrument, and a swing transmitting member provided to the frame so as to be interposed between the adjusting screw and the lever member. The swing transmitting member is swingably supported by the frame and includes one or more transmitting levers extending along the string. When the adjusting screw is screwed into the mounting portion, one end of the transmitting lever is pushed down and another end pushes up the lever member, and the anchoring portion is swung to stretch the string.

Abstract: An adjuster for tuning of a string instrument.

Abstract: The mounting position of a winding shaft on a main body is changed, and a peg may be mounted in various stringed instruments by miniaturizing the main body or reducing the thickness thereof. The peg for the stringed instrument includes a main body mounted in the stringed instrument; a worm rotatably supported by the main body, the worm having a knob at an end thereof; a worm wheel engaging with the worm, the worm wheel rotatably supported by the main body; a winding shaft connecting to one side of the worm wheel in an axial direction, the winding shaft for winding a string of the stringed instrument; and bearing holes formed in at least two surfaces of the main body, the bearing holes supporting the winding shaft rotatably.

Abstract: A peg for a stringed instrument has a knob made of metal which has an internal hollow portion. The knob is light in weight and has a reduced wall thickness because the hollow portion is formed therein. Therefore, the responses of vibrations of strings during performances are fast, and tone and afterglow of sounds are good. A high-quality appearance is provided by the metal knob. A smaller sprue may be used because a smaller amount of melted metal is required when the knob is cast, and the mark of the sprue formed on a surface of a molded knob is therefore be smaller when the melted metal is injected through the sprue. Formation of blowholes caused by gas contained in the knob molded by casting can be reduced because the wall of the knob is thin.

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.

Abstract: A peg for a stringed instrument is provided, The peg has a main body 10; a pair of bearings 12 erected at two sides of the main body so as to oppose each other, a worm gear 21 which is rotatably supported in a large diameter hole 15 and a small diameter hole 16 which has a knob 29 on one end portion, and a winding shaft 30 which is connected to the worm gear 21 via a worm wheel 40. The bearing 12 is formed of a material having spring-like properties and thus has increased elastic limit and avoids deformation.
