SCREW DRIVING MACHINE

To provide a screw driving machine in which a screw can be easily taken out from an injection part.SOLUTION: A screw driving machine has: an injection part 12 which accommodates a screw 82; a rotary striking part 14 which can contact the screw 82 in the injection part 12, is rotatable around an axis A1, and is movable in the axis A1 direction; a striking force application mechanism which applies a striking force of the axis A1 direction to the rotary striking part 14; a torque application mechanism which applies a torque to the rotary striking part 14; and a guide mechanism 84 which contacts the screw 82 in the injection part 12, thereby suppressing change in an attitude of the screw 82. An adjustment mechanism 99 is provided for adjusting a force of contact of the guide mechanism 84 with the screw 82.SELECTED DRAWING: Figure 6 【課題】ねじを射出部から取り出し易いねじ打機を提供する。【解決手段】ねじ８２を収容する射出部１２と、射出部１２のねじ８２に接触可能であり、かつ、軸線Ａ１を中心として回転可能、かつ、軸線Ａ１方向に移動可能な回転打撃部１４と、回転打撃部１４に軸線Ａ１方向の打撃力を与える打撃力付与機構と、回転打撃部１４に回転力を与える回転力付与機構と、射出部１２のねじ８２に接触することにより、ねじ８２の姿勢が変化することを抑制するガイド機構８４と、を有するねじ打機であって、ガイド機構８４がねじ８２に接触する力を調整する調整機構９９が設けられている。【選択図】図６
