This item is a fishing tackle component used in fishing for pufferfish and other fish. As shown in the "Reference Oblique View," the upper part of this item is roughly cylindrical, while the lower part is trifurcated and equipped with three line holders. "Reference Figure 1 Showing the State of Use" and "Partial Enlargement of Reference Figure 1 Showing the State of Use" show an example of a cuttlefish rig made using this item. In this figure, the line that passes through this item and extends upward forms a loop, to which the line from the fishing rod is connected via a snap swivel. Meanwhile, the line that passes through this item and extends downward is equipped with a cuttlefish hook. The cuttlefish hook may be attached via a swivel, as shown in "Reference Figure 2 Showing the State of Use." A sinker is threaded through the line that passes through this item and extends upward. Attaching rubber beads (elastic material) to the roughly cylindrical part of this item can prevent the sinker from contacting the item. Each line holder of this item is equipped with a chisara hook. "Reference Figure 1 Showing the Chisara Hook" shows an example of a chisara hook that can be attached to this item. As shown in this figure, the chisara hook has a hook body at the tip of the leader and a knot (knot) at the base end of the leader. If desired, the leader may be provided with a tangle stopper (luminous pipe). As shown in the "Reference Perspective View," each leader stopper of this article has a roughly U-shaped portion and an expanded portion connected to the upper part of the U-shaped portion. To attach a chisara hook to a leader stopper, as shown in "Reference Figure 1 Showing How to Attach a Chisara Hook," the knot of the chisara hook is passed through the expanded portion of the leader stopper from the outside to the inside (in a plan view of the article). Then, the leader of the chisara hook is pulled downward along the groove of the roughly U-shaped portion of the leader stopper. This causes the knot of the chisara hook to hook onto the lower end of the leader stopper, holding the chisara hook to the article, as shown in "Reference Figure 2 Showing How to Attach a Chisara Hook." Chisara hooks can be attached to other leader stoppers in a similar manner. Conversely, to remove the chisara hook from the leader stopper, simply pull it upward along the groove in the roughly U-shaped section. Also, "Reference Diagrams 1 and 2 Showing How to Attach the Chisara Hook" show an example in which an elastic material is attached to the roughly cylindrical section of this product. Since the chisara hooks are each detachably attached to the three leader stoppers, even if one of the chisara hooks is damaged, it is possible to replace each individual chisara hook without having to replace the entire rig.As shown in "Reference Figure 2 showing the chirashi needles," multiple types of chirashi needles can be prepared and replaced depending on the situation. As shown in "Reference Figure 3 showing the state of use" and "Reference Figure 4 showing the state of use," master needles or other parts can be similarly attached instead of the chirashi needles. Alternatively, as shown in "Reference Figure 5 showing the state of use," it is possible to use only the cut-off needles without attaching the chirashi needles. In this way, by using this product, various rigs can be created, and rig changes can be made easily and quickly. Furthermore, for example, it is possible to replace only some of the chirashi needles, which can reduce costs.
