- the detection portion main body 21a detects the feeder portion 20b when the number of fasteners 6 loaded in the base member 20a becomes zero. For that purpose, it is necessary to detect a slight movement of the feeder portion 20b corresponding to one stopper 6, and it is necessary to improve the accuracy of position detection of the feeder portion 20b by the detection portion 21.
- the pressing section 20h of the feeder section 20b does not directly press the protruding section 21b of the detection section main body 21a, but rather the pressing section 20h of the feeder section 20b presses the lever section 21c so that it is pressed.
- the lever portion 21c rotates to press the protruding portion 21b of the detection portion main body 21a. This makes it possible to press the projecting portion 21b even if the pressing portion 20h of the feeder portion 20b presses the lever portion 21c in a smaller amount than when the pressing portion 20h of the feeder portion 20b directly presses the projecting portion 21b. It is possible to improve the accuracy of position detection of the portion 20b.
