PROBLEM TO BE SOLVED: To provide a screw automatic feeder in an automatic driver that can make the automatic feed of a machine screw the shank length of which is smaller than the diameter dimension of the head to a bit tip of the automatic driver smoother, rapid, secure, and simple in the case of automatically feeding the screw to the automatic driver and significantly enhance an efficiency of screw tightening.SOLUTION: A screw feeding pipe 40A is provided which consists of a cylindrical flexible tube provided with a screw guide through-hole 42 consisting of a screw head guide through-hole part 43 flatly shaped to guide a screw head Sa and a screw shank guide through-hole part 44 narrowly shaped to the shank part by crossing the screw head guide through-hole part in cross sectional T, and which forms an inner face corresponding to an outer shape of the tube of the screw head guide through-hole part 43 into an arch type curved inner face 43a. 【課題】自動ドライバーに対し、ねじ軸部の長さがねじ頭部の直径寸法よりも小さくなるような小ねじの自動供給を行う場合において、自動ドライバーのビット先端部への前記ねじの自動供給を、より円滑にして迅速かつ確実に、しかも簡便に行うことができると共に、ねじ締め作業の効率化を著しく高めることができる自動ドライバーにおけるねじ自動供給装置を提供する。【解決手段】ねじ頭部Ｓａを案内するための扁平な形状からなるねじ頭部案内通孔部４３と、前記ねじ頭部案内通孔部に対し断面Ｔ字状に交差してねじ軸部を案内する細幅な形状からなるねじ軸部案内通孔部４４とからなるねじ案内通孔４２を設けた円筒状の可撓性チューブからなり、前記ねじ頭部案内通孔部４３の前記チューブ外形に対応する内面をアーチ型の湾曲状内面４３ａに形成してなるねじ供給管４０Ａを設ける。【選択図】図１
