FASTENING TOOL

摘要

When bolts are fastened to tack a door to a car body by means of a conventional impact wrench, the shavings stick to the surface of the door or car body, thereby to cause the poor coating quality such as a seeding when the inter-coating or finish-coating is performed in the coating procedure. An impact wrench (1) provided is a fastening tool for fastening a bolt (51) gripped by a socket (6), in a nut (70a). The impact wrench (1) includes a suction cover (12) for covering the surroundings of the socket (6), and a suction port (11 d) capable of sucking the atmosphere in the portion covered with the suction cover (12), and is constituted such that the atmosphere in the suction cover (12) is sucked through the suction port (11 d) to recover the shavings left at the time of fastening the bolt (51). This constitution makes it possible to prevent the shavings from being scattered to the surroundings. When the door is temporarily attached at the coating step to a car body (70), the poor coating quality such as the seeding, as might otherwise be caused by the shavings stuck to the surface of the car body (70) or door, can be prevented and improved.
