PROBLEM TO BE SOLVED: To provide a nut delivery device which assuredly inserts a nut into a socket of a nut fastening device by aligning the nut in phase therewith.SOLUTION: In the nut delivery device, a frictional resistance R2 of a contact part of the nut 16 and a set base 15 is made to be larger than a frictional resistance R1 of a contact part of the socket 8 and the nut 16 in order to prevent the nut 16 from rotating together with the socket 8. Accordingly, an angle of an internal tapered surface 17 to a vertical direction is set to 14° or smaller. Thus, since the angle of the internal tapered surface 17 is 14° or smaller, even when a lower end of the socket abuts on the nut, the nut is not rotated together with the socket, and the phase can be assuredly aligned. |
