The resin part is Two types of locking claws, long and short, extending toward the center of each hole are provided alternately. The longer locking piece is long enough to reach near the center of the locking hole. Also, short The other locking piece has a length that slightly protrudes toward the center of the locking hole, and the countersunk When a headed bar with a shaped head is pushed into a locking hole, its countersunk head is inserted into the longer end. It is configured so that the locking piece holds it while the shorter locking piece holds it down. There is.

[0006]

[Effect]

The above-mentioned resin belt for holding a headed bar can hold a headed bar having a dish-like head. When inserting the headed bar into the locking hole, remove the countersunk-like head from the resin part sufficiently. When pushed in until it sinks, the plate-like head is held by the long locking piece while the short Push and bend the locking piece on the other side and pass through. After that, the pushing of the headed bar is finished. Then, the elastic force of the longer locking piece pushes up the dish-like head and pushes it against the shorter locking piece. Can be held together. Moreover, this saucer-like head has multiple Since it is held by the locking piece, its posture is stable and it is held in a line on the resin part. Therefore, this resin belt for holding headed bars can be used to hold headed bars in automatic tools. When feeding, the headed bar is guided through a predetermined feed path to ensure that it reaches the desired position. It is possible to completely eliminate problems such as insufficient supply of headed bars.
