To efficiently and quickly feed a nut by providing a supporting part for supporting a bolt, a gripping part having the inner periphery to be matched to the nut through a bolt and for gripping the outer periphery of the nut, a rotational driving part for rotating the gripping part, and a stopper means for limiting the axial moving distance of the bolt.

This nut feeding device 1 is provided with a main body 2, a supporting part 3 provided on one end of the main body 2 in order to slidably axially supporting a bolt, a gripping part 4 for gripping the nut screwed to the bolt, a rotational driving part 5 for rotating the gripping part 4, and a stopper means 6 for limiting the axial moving distance of the bolt. The gripping part 4 for gripping the nut is provided in such a position that the axis of the bolt supported on the supporting part 3 may coincide with the gripping center. Therefore, the nut can be efficiently and quickly fed to the specified position of the bolt.
