One clip nut 10 is supplied to the supply position in a predetermined mounting posture. Thus, a series of operation cycles for mounting one clip nut 10 is completed.

As described above, according to the clip nut mounting device 50 of the present embodiment, the clip nuts 10 are sequentially supplied to the supply positions in the guide grooves 122 in a predetermined mounting posture, and the pusher 124 is moved by the mounting air cylinder 68. Since it is automatically mounted on the mounting member 30 by being advanced, the burden on the operator can be greatly reduced and the mounting time can be shortened.

The engaging pin 132 is always held at the projecting position by the compression coil spring 176, while the pair of retreating claws 1 moved integrally with the pusher 124.
Since the engaging pin 78 is engaged with the flange 172 of the engaging pin 132, the engaging pin 132 is retracted to the retracted position by a wedge action. As compared with the case where the engaging pin 132 is moved forward and backward by the
The engagement pin 132 is mechanically retracted in conjunction with the operation, so that the operation is stable and high reliability is obtained.
