Abstract
An air cylinder is joined to a guide pipe via a joining member. A stopper member is arranged in a position where the guide pipe and a feed pipe for feeding a projection nut are coupled to form a temporary locking chamber of the nut. A sliding rod is integrated with a smaller diameter guide rod and enters a screw hole. Relative positions of the temporary locking chamber and a feed rod are set such that the screw hole of the nut stopped in the temporary locking chamber is coaxial with the feed rod. A gap is formed between the sliding rod and the guide pipe while a support hole is formed in an end part of the guide pipe, and when the feed rod is retracted, the sliding rod is supported in a state where a slight sliding gap is left in the support hole.
