PURPOSE:To make a piece or two pieces of parts feedable, by making a shuttle plate being free of reciprocation stoppable in the point midway in its stroke with a stopper, and constituting this stopper so as to be separable from a moving passage of the shuttle plate. CONSTITUTION:When a parts feeding command signal is emitted there, first a shuttle plate 6 is retracted by a small diametral cylinder 7, hitting a stopper 8, and it comes to a stop. At this time, an engaged groove 6a is interconnected to a first takeout hole 10 whereby the nut 2 held by this engaged groove 6a drops in the said hole 10 and is taken out by air to be fed out of an air feed hole 16. Afterward, the shuttle plate 6 is made to go forward till it hits a stopper 17, and the nut 2 is fed to the inside of the engaged groove 6a from a chute rail 3. In addition, when the nut 2 is fed out of both first and second takeout holes 10 and 11, the stopper 17 is retracted by a large diametral cylinder 18 and, after the shuttle plate 6 is made to go forward till it hits a stopper 9, making it operate as mentioned above.
