[0001]

FIELD OF THE INVENTION The present invention relates to spools, and in particular to
The present invention relates to a spinning reel spool that can be moved back and forth with respect to a reel body.

[0002]

2. Description of the Related Art Generally, a spinning reel includes a reel body that rotatably supports a handle, a rotor, and a spool rotatably mounted on a spool shaft.
The spool of the spinning reel is movable back and forth with respect to the reel body, and has a bobbin trunk around which fishing line is wound, a large-diameter cylindrical skirt provided at the rear end of the bobbin, and a bobbin A front flange portion provided at a front end portion of the portion, and a front flange portion fixing member for fixing the front flange portion to the bobbin trunk.

As a front flange portion provided on a spool of such a spinning reel, a front flange portion fixing member is screwed and fixed to the front end portion of the bobbin trunk portion, or a front flange portion fixing member and a bobbin trunk portion are provided. It is known that a male screw portion and a female screw portion are formed, and these are screwed to each other to sandwich and fix the front flange portion.

[0004]

In the conventional spinning reel spool, when the front flange portion and the front flange portion fixing member are screwed and fixed to the front end portion of the bobbin trunk, the front flange portion and the front flange portion are fixed. Since it is necessary to form a plurality of holes for inserting screws in the member, it may take time and labor to process the holes, and the manufacturing cost may increase.

Further, when the front flange portion is sandwiched between the front flange portion fixing member and the bobbin trunk, the bobbin trunk must be machined with high precision because the female thread portion must be formed on the inner peripheral side of the bobbin trunk with high accuracy. It can be difficult. When it becomes difficult to process the bobbin trunk as described above, the manufacturing cost may increase. An object of the present invention is to make it possible to fix a front flange portion of a spinning reel spool with an inexpensive structure.

[0006]

A spool of a spinning reel according to a first aspect of the present invention is a spool of a spinning reel mounted to a reel body so as to be movable back and forth, and a fishing line winding body around which fishing line is wound. A skirt portion provided at the rear end of the bobbin trunk, a front flange fixing member that is provided at the front end of the bobbin trunk so as to project radially outward, and a bobbin trunk so as to abut the front flange fixing member. And an annular front flange portion mounted from the side.

In the spool of this spinning reel, the front flange portion is mounted so as to come into contact with the front flange portion fixing member from the bobbin trunk side, so that the front flange portion can be fixed easily. Since it is not necessary to form a hole or to process the inner peripheral side of the bobbin trunk as in the conventional case, the front flange can be fixed with an inexpensive structure. Further, when the fishing line is wound around the bobbin trunk, a force is generated by the wound fishing line to push the front flange portion toward the front flange portion fixing member side, so that the front flange portion is firmly fixed.

A spool according to a second aspect of the present invention is the spool of the first aspect, wherein a male thread portion is formed on the outer circumference of the front flange portion fixing member, and a female thread portion that is screwed into the male thread portion is formed on the inner circumference of the front flange portion. ing. In this case, the front flange portion and the front flange portion fixing member can be easily fixed by screwing the female screw portion of the front flange portion into the male screw portion of the front flange portion fixing member.

A spool according to a third aspect of the present invention is the spool of the second aspect, in which the male screw portion and the female screw portion are formed with threads in the yarn feeding direction of the bobbin trunk. In this case, since the screw directions of the male screw part and the female screw part are formed so as to be tightened in the line feeding direction of the bobbin trunk part, the front flange part is accordingly rotated by the screw tightening direction, so that the fishing operation is performed. It is possible to prevent the front flange portion from loosening at the time.

A spool according to a fourth aspect of the present invention is the spool according to any one of the first to third aspects, in which the front flange portion is formed by machining. In this case, the machining accuracy of the front flange portion can be improved by forming the front flange portion by machining such as cutting. A spool according to a fifth aspect of the present invention is the spool according to any one of the first to fourth aspects, wherein the front flange portion is bonded to the front flange portion fixing member. In this case, the front flange portion is securely fixed to the front flange portion fixing member.

A spool according to a sixth aspect of the present invention is the spool according to any one of the first to fifth aspects, wherein the front flange portion is made of a stainless alloy. In this case, the strength of the front flange portion can be kept high by the stainless alloy. A spool according to a seventh aspect of the present invention is the spool according to any one of the first to fifth aspects, wherein the front flange portion has a component body made of an aluminum alloy and a ceramic layer formed on the surface of the component body. In this case, the workability of the front flange portion can be improved by the aluminum alloy, and the rigidity can be kept high by the ceramic layer formed by, for example, welding or vapor deposition.

A spool according to an eighth aspect of the present invention is the spool according to any one of the first to seventh aspects, wherein the bobbin trunk has a tubular portion integrally formed with the skirt portion by a thin metal plate, and a tubular member provided separately from the skirt portion. The inner cylindrical member integrally mounted with the front flange portion fixing member is attached to the inner peripheral side of the shaped portion. In this case, since the tubular portion is integrally formed with the skirt portion by a thin metal plate such as an aluminum alloy, the weight of the entire spool can be reduced. Further, by mounting an inner tubular member made of, for example, a synthetic resin on the inner peripheral side of the tubular portion, the strength of the bobbin trunk can be maintained high.

A spool according to a ninth aspect of the present invention is the spool according to any one of the first to seventh aspects, wherein the bobbin trunk has a tubular portion integrally formed with the skirt portion by a thin metal plate, and a tubular member provided separately from the skirt portion. It has an inner cylinder member formed separately from the front flange portion fixing member attached to the inner peripheral side of the shaped portion. In this case, since the front flange part fixing member and the inner cylinder member are formed separately, after mounting the front flange part to the front flange part fixing member from the bobbin trunk side, fix the front flange part to the inner cylinder member. The member can be easily fixed.
