However, since this clip feeding device 2 has a structure in which the rear part of the clip assembly 8 is pushed by the force of the spiral spring 5 via the feeding member 4, it is necessary to load the entire clip assembly 8 into the feeding passage 3. Therefore, the length of the clip assembly 8 is limited by the length of the feed path 3. Moreover, feed passage 3
If the length of the clip assembly 8 is too long, it becomes difficult to fasten the clip, so the length of the clip assembly 8 loaded into the feed passage 3 cannot be increased. For this reason, the number of clips 6 that can be loaded at one time is small, and the number of times the clip assembly 8 is loaded into the feed path 3 increases, resulting in a decrease in the efficiency of the clip fastening operation.

Therefore, a clip feeding device (Japanese Unexamined Patent Application Publication No. 1989-1989) as shown in Fig. 3 and Fig. 4 (BB sectional view in Fig. 3)
77821) is being considered. In the figure,
A wire 9 is attached to the head of the U-shaped clip 6, and the clip 6 and wire 9 constitute a U-shaped clip assembly 10. 11 is a feeding path for the clip 6 attached to the U-shaped clip fastening device main body 1; 12 is a side plate 11a of the feeding path 11;
