Abstract
A joint includes a joint main body, a sleeve and a nut. The joint main body has a joining hole and an external threaded part. The nut is threaded onto the external threaded part in a threaded state in which the pipe and the sleeve are inserted through the joining hole. The nut joins the pipe to the joining hole via the sleeve. The sleeve is tightly fitted to the pipe and the joining hole by the threading of the nut to induce deformation that expands radially outward. The deformation prevents insertion of the sleeve into the joining hole to a specific position in an unthreaded state in which the pipe and the sleeve have been pulled out from the joining hole.
