とする吸引式ねじ締め機。[Claims for Utility Model Registration] A pair of chuck pawls 6 are rotatably disposed in a chuck body 4 having a guide hole 5 through which a rotatable driver bit 2 and a suction sleeve 3 for inserting the same are inserted. The tip of the chuck claw 6 is always elastically biased in the closing direction to form a screw holding hole 6a for holding a desired screw 9 at the tip, and a screw hole 6a is formed near the end of the suction sleeve 3. A guide part 3a for guiding the driver bit 2 is provided, and an air communication path is provided in the driver bit 2, the ends of which are positioned on both sides of the guide part 3a, so that the driver bit 2 can be placed in place with respect to the suction sleeve 3. In a suction type screw tightening machine configured to close one end of an air communication path by a guide portion 3a when a certain amount of relative movement is made, the driver bit 2 is composed of a bit shaft 2a and a tip bit 2b, and the axis line is set to the bit shaft 2a. A communication hole 12 extending along is bored, and the tip bit 2b is fixed to the bit shaft 2a so as to close the communication hole 12, and air holes 13a, 13b communicating with the communication hole 12 are provided in the bit shaft 2a. The air holes 13a are bored at predetermined intervals, and one air hole 13a is located inside the guide part 3a of the suction sleeve 3, and the other air hole 13b is located outside the guide part 3a, so that the suction sleeve 3 and the driver bit are connected to each other. 2. A suction type screw tightening machine characterized in that the inner air hole 13a is closed by the guide part 3a when the two move a predetermined amount relative to each other.
