PROBLEM TO BE SOLVED: To provide a screwing fastening machine generating low impact and low noise and having a long life.SOLUTION: A screwing fastening machine 1 comprises: a motor 3 having a rotary driven rotating shaft part 32; and an end-bit mounting part 5 to which a bit 10 rotary driven to tighten a screw can be attached. A disk friction clutch 4 is interposed between the end-bit mounting part 5 and the motor 3. The friction clutch 4 comprises: a first clutch plate 43 integrally rotated with the motor 3; and a second clutch plate 44 integrally rotated with the end-bit mounting part 5. The friction clutch is movable between a transmission position where the rotating shaft part 32 is connected to the end-bit mounting part 5 by generating friction between the first clutch plate 43 and the second clutch plate 44 and a cutoff position where the first clutch plate 43 and the second clutch plate 44 are not brought into contact with each other.SELECTED DRAWING: Figure 1 【課題】低衝撃で低騒音、かつ高寿命のねじ締め機の提供。【解決手段】回転駆動される回転軸部３２を有するモータ３と、回転駆動されてネジを締め付けるビット１０を装着可能な先端工具装着部５と、を備え、先端工具装着部５とモータ３との間には板摩擦クラッチ４が介在し、摩擦クラッチ４は、モータ３と一体回転する第一クラッチプレート４３と先端工具装着部５と一体回転する第二クラッチプレート４４とを有し、第一クラッチプレート４３と該第二クラッチプレート４４との間に摩擦を発生させて回転軸部３２と先端工具装着部５とを連結する伝達位置と、第一クラッチプレート４３と該第二クラッチプレート４４とが非当接の遮断位置との間で移動可能に構成されたねじ締め機１を提供する。【選択図】図１
