<p>PROBLEM TO BE SOLVED: To provide an automobile screw fastener which can perform proper screw-fastening irrespective of a length and a shape of a screw.SOLUTION: An adsorption pipe 24 and a driver bit 22 which becomes non-rotatable in the adsorption pipe 24 are arranged at an automatic screw fastener A which screws an oval head screw 17 supplied from a screw supply device to a matter to be fastened, and the driver bit 22 is rotated by the operation of a drive motor 13. An intake passage is formed between the adsorption pipe 24 and the driver bit 22, and the oval head screw 17 located in the vicinity of an opening of the adsorption pipe 24 can be suctioned by a suction pump. Furthermore, a magnet 26 is arranged at an internal peripheral face of a tip side of the suction pipe 24, and the oval head screw 17 can be suctioned even by a magnetic force of the magnet 26.</p> |
