<p><P>PROBLEM TO BE SOLVED: To provide a nut runner which can improve workability and working efficiency, and suppress cost for change parts. <P>SOLUTION: The nut runner 10 connects a first exhaust system 60 and a first high-pressure air blowing system 70 to a shaft sealing part 20, a bolt is sucked to and held at a socket 21 by actuating the first exhaust system 60, the bolt is exhausted by high-pressure air by actuating the first high-pressure air blowing system 70, and the inside of the socket 21 is cleaned by the high-pressure air. Accordingly, since the head of the bolt is easily fitted to the socket 21 by the first exhaust system 60, workability is improved. Moreover, since the bolt can be easily removed from the socket 21 by the first high-pressure blowing system 70, working efficiency is improved. Since iron powder does not remain in the socket 21, the wear of the head of the bolt and the inner surface of the socket 21 is reduced. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
