PROBLEM TO BE SOLVED: To deal with a problem which requires stability and easiness of hand inserting operation as well as easiness of maintenance when machining dust sticks to a pinch roller gear or the like, while a feeding apparatus of thread solder grooving for the use of automatic soldering requires easy operability and maintenance and high-working rate operation, where there is unstable hand operation performed by an opeator in inserting thread solder at the start of the apparatus operation and where there is malfunctioning in the occurrence of machining dust sticking to a pinch roller gear or the like. SOLUTION: Knurling is performed on a guide roller or slotting is performed on the upper end face of the guide roller, with a structure formed to make hand turning, coin handling, lever handling, etc., possible. Also, with a dustproof gear case installed that is easy to be removed, and by combining with a rotary seal or supplying an internal pressure into the case, a sealing effect is enhanced.
