Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to spools, and in particular to
The present invention relates to a spinning reel spool which is provided so as to be movable back and forth with respect to a reel body and around which a fishing line is wound.

[0002]

2. Description of the Related Art Generally, a spinning reel comprises a reel body, a rotor rotatably supported by the reel body, and a spool which is arranged in front of the rotor and around which a fishing line is wound. Such a spool has a bobbin trunk around which fishing line is wound, and a skirt provided in a large-diameter tubular shape at the rear end of the bobbin trunk. The bobbin trunk and the skirt are two large and small tubular members,
For example, it is integrally molded of synthetic resin or metal. Particularly, in a spinning reel for throwing fishing, the distance from the front end to the rear end of the skirt is formed to be much smaller than that of the bobbin trunk.

[0003]

In the conventional spinning reel spool, particularly, the spinning reel spool for throwing fishing has a very small distance from the front end to the rear end of the skirt portion. The raised fishing line rides on the skirt portion, and further, the fishing line falls from the rear end of the skirt portion into the gap between the skirt portion and the rotor, so-called line drop easily occurs.

Therefore, it is known that an annular thread drop preventing member for closing a gap between the skirt portion and the rotor is mounted on the rotor. By mounting the line drop prevention member, the movement of the fishing line caused by the line dandruff is restricted, so that the line drop in the gap between the skirt portion and the rotor can be prevented. However, since the yarn drop prevention member is provided separately from the rotor and the spool, the yarn drop prevention member is likely to be an obstacle when the spool is replaced with the rotor when the spool is replaced. Further, by providing the thread drop prevention member as a separate body, the number of parts as a whole is increased, which may complicate the structure of the spool.

SUMMARY OF THE INVENTION An object of the present invention is to prevent a yarn drop in a spinning reel spool with a simple structure.

[0006]

A spool of a spinning reel according to a first aspect of the present invention is a spool of a spinning reel which is provided so as to be movable back and forth with respect to a reel unit and around which a fishing line is wound, the fishing line being wound around the outer periphery. A tubular bobbin trunk, and a skirt portion having a large-diameter tubular shape at the rear end of the bobbin trunk, at least a portion of which is formed so that the outer diameter is reduced from the rear end toward the front end. Is equipped with.

In this spool, at least a part of the skirt portion is formed in a so-called forward taper shape in which the outer diameter is reduced from the rear end portion toward the front end portion. Therefore, even if the fishing line with dandruff rides on the skirt, at least a part of the skirt is formed in a forward tapered shape, so that the fishing line is guided to the front end side of the skirt and the rear end of the skirt The fishing line does not easily fall into the gap between the rotor portion and the skirt portion and the rotor. Therefore, it is not necessary to separately provide the yarn drop prevention member as in the conventional case, and thus the yarn drop can be prevented with a simple configuration.

A spool according to a second aspect of the present invention is the spool of the first aspect, wherein the entire skirt portion is formed so that the outer diameter thereof decreases from the rear end portion to the front end portion. in this case,
Since the entire skirt is formed in a forward tapered shape,
The fishing line, which causes the dandruff and rides on the skirt, is easily guided to the front end side of the skirt. Invention 3
According to the spool of the invention 2, in the spool of Invention 2, the distance (A) between the front end and the rear end of the skirt, the outer diameter of the front end of the skirt, and the outer diameter of the rear end of the skirt. The ratio (A / B) to the diameter difference (B) is in the range of 0.08 or more and 0.2 or less. In this case, assuming that the inclination angle of the skirt portion is α, tan α = A / B, so 0.08 ≦ tan
α ≦ 0.2, and the inclination angle α is in the range of approximately 5 degrees to 10 degrees. Here, the fishing line which has caused the dandruff and has run on the skirt portion is more easily guided to the front end side of the skirt portion.

A spool according to a fourth aspect of the present invention is the spool according to any one of the first to third aspects, wherein the distance (A) between the front end portion and the rear end portion of the skirt portion and the front end portion and the rear end portion of the bobbin trunk are provided. The ratio (A / C) to the distance (C) between and is in the range of 0.25 to 0.67. In this case, the spool is a spinning reel spool for pitch fishing, in which the distance from the front end to the rear end of the skirt is much smaller than that of the bobbin trunk. Here, the effect of the present invention becomes remarkable by applying the present invention to the spool of the spinning reel for pitch fishing.

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 bobbin trunk is formed so that the outer diameter thereof decreases from the rear end portion to the front end portion. In this case, since the bobbin trunk is formed in a forward taper shape in which the outer diameter is reduced from the rear end to the front end, the fishing line wound around the bobbin can be easily fed. A spool according to a sixth aspect of the present invention is the spool of the fifth aspect, wherein a difference (D) between the outer diameter of the front end portion of the bobbin trunk and the outer diameter of the rear end portion of the bobbin trunk, and the front end and the rear end of the bobbin trunk. The ratio (D / C) to the distance (C) from the end is in the range of 0.05 or more and 0.13 or less. In this case, assuming that the inclination angle of the bobbin trunk is β, tan β = D / C, so 0.05 ≦ tan
β ≦ 0.13, and the inclination angle β is in the range of approximately 3 degrees to 7 degrees. Here, it becomes easier to feed the fishing line wound around the bobbin trunk.

A spool according to a seventh aspect of the present invention is the spool of the first aspect, wherein a part of the skirt portion has an inclined portion formed so that the outer diameter thereof decreases from the rear end portion to the front end portion. In this case, since the inclined portion is formed on the skirt portion, the fishing line that has caused the line dandruff and runs on the inclined portion is easily guided to the front end side of the inclined portion. A spool according to an eighth aspect of the present invention is the spool of the seventh aspect, wherein the inclined portion is formed at the front end portion of the skirt portion. In this case, since the inclined portion is formed at the front end portion of the skirt portion, it is possible to guide the fishing line that has caused dandruff early to the front end portion side of the inclined portion.

A spool according to a ninth aspect of the present invention is the spool according to the seventh or eighth aspect, wherein the distance (E) between the front end and the rear end of the inclined portion, the outer diameter of the front end of the inclined portion, and the rear portion of the inclined portion. The ratio (E / F) to the diameter difference (F) from the outer diameter of the end portion is in the range of 0.08 to 0.2. In this case, assuming that the inclination angle of the skirt portion is γ, tan γ = E / F, so 0.
08 ≦ tan γ ≦ 0.2, and the inclination angle γ is in the range of approximately 5 degrees to 10 degrees. Here, it becomes easier to guide the fishing line, which is caused by dandruff and rides on the inclined portion, to the front end side of the inclined portion.

The spool according to the tenth aspect of the invention is the first to ninth aspects of the invention.
In any one of the above spools, the spool further includes an annular protruding portion that is provided at a rear end portion of the skirt portion and that projects radially outward of the skirt portion. In this case, the rearward movement of the fishing line is restricted by the protrusion provided integrally or separately at the rear end of the skirt portion, so that the line drop can be reliably prevented.
