PROBLEM TO BE SOLVED: To well drive a nail at all times regardless of whether an air duster is used. SOLUTION: A conduit 18 for an air duster is branched from an intermediate part of an air conduit 17 interconnecting an air supply source 16, which supplies compressed air, and an air tool. A valve mechanism having a switchover valve 25 and operation means 35 is installed at the branched part. The switchover valve 25 is movable between a first position and a second position. At the first position, an upstream side conduit 17a communicating with the air supply source 16 is connected to a downstream side conduit 17b, which communicates with a nailing device, and disconnected from the branched conduit 18 for an air duster. At the second position, the upstream side conduit 17a is disconnected from the downstream side pipeline 17b and connected to the branched conduit 18. The switchover valve 25 is operated by the operation means 35 from the outside. COPYRIGHT: (C)2008,JPO&INPIT
