Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a spool, and more particularly to a spool of a dual bearing reel having a fishing line locking portion for locking a winding start end of a fishing line.
[0002]
[Prior art]
In general, a dual-bearing reel includes a reel body having a handle and a spool rotatably mounted on the reel body. The spool has a bobbin trunk and flanges provided at both ends of the bobbin trunk. The bobbin trunk has a cylindrical shape around which the fishing line is wound, and the flange portion has a larger diameter than the outer diameter of the bobbin trunk. The inner periphery of the bobbin trunk is attached to the spool shaft. A fishing line locking part for locking the winding start end of the fishing line wound around the bobbin trunk is provided on the outer periphery of the bobbin trunk.
[0003]
For example, a fishing line locking portion is well known in which a rod-shaped locking pin is erected at a substantially central portion of a bobbin trunk. The locking pin is provided so that a portion around which the fishing line is wound protrudes outward from the outer peripheral surface of the bobbin trunk.
[0004]
[Problems to be solved by the invention]
Since the conventional fishing line locking portion is provided so that the locking pin protrudes outward from the outer peripheral surface of the bobbin trunk, a step is likely to occur in the bobbin shape when the fishing line is wound around the bobbin trunk. . In particular, when a fishing line is wound around a shallow groove spool in which the outer diameter of the bobbin trunk is 40% or more of the outer diameter of the flange portion, the entire amount of the fishing line is wound, and the step of the bobbin shape becomes more conspicuous.
[0005]
An object of the present invention is to make it difficult for a spool of a dual-bearing reel to have a step difference in a bobbin shape of a fishing line wound around a bobbin trunk.
[0006]
[Means for Solving the Problems]
A spool of a dual-bearing reel according to a first aspect of the present invention is a spool of a dual-bearing reel that is rotatably supported with respect to a reel body and is mounted on a spool shaft. A trunk portion, flange portions provided at both ends of the bobbin trunk portion, and a locking pin having a fishing line locking portion in which the base end portion is embedded in the bottom surface of the recess and the tip end locks the fishing line in the recess. Yes. The bobbin trunk has a stepped through hole formed in the bottom surface of the recess. The locking pin is formed so that the distal end portion has a larger diameter than the base end portion, and the distal end portion is locked to the step portion of the through hole when the base end portion is inserted into the through hole.
[0007]
In such a spool, the locking pin is embedded in a recess formed in the bobbin trunk, and the fishing line is locked to the fishing line locking portion at the tip of the locking pin. In this case, since the fishing line locking portion is located in the recess, when the fishing line locked to the fishing line locking portion is wound around the bobbin trunk, it is difficult to make a significant change in the bobbin shape. Therefore, it is possible to make it difficult for a line-shaped step when the fishing line locked to the fishing line locking portion is wound to be generated.
[0008]
The spool according to the second aspect of the invention is the spool of the first aspect, wherein the fishing line locking portion is provided so as not to protrude outward from the outer peripheral surface of the bobbin trunk.
[0009]
In this case, since the fishing line locking portion is provided so as not to protrude outward from the outer peripheral surface of the bobbin trunk, the fishing line locking portion can be reliably positioned in the recess.
[0010]
A spool according to a third aspect is the spool according to the first or second aspect, wherein the fishing line locking portion is a groove portion into which the fishing line can be locked.
[0011]
In this case, for example, a fishing line locking portion is formed along the circumferential direction of the front end portion of the locking pin, and the fishing line is easily locked by winding and locking the fishing line around the groove portion.
[0012]
A spool according to a fourth aspect is the spool according to the first or second aspect, wherein the fishing line locking portion is a through hole in which the fishing line can be locked.
[0013]
In this case, the fishing line can be reliably locked by locking the fishing line in the through hole.
[0014]
A spool according to a fifth aspect is the spool according to any one of the first to fourth aspects, wherein the locking pin penetrates the bobbin trunk.
[0015]
In this case, the fixing between the bobbin trunk and the locking pin can be further strengthened.
[0016]
A spool according to a sixth aspect is the spool according to the fifth aspect, wherein the spool shaft further includes an engagement hole communicating with the through hole of the bobbin trunk, and the locking pin is inserted through the through hole and the engagement hole.
[0017]
In this case, by engaging the locking pin with the bobbin trunk and the spool shaft, the spool shaft can also be used as a detent.
[0018]
A spool according to a seventh aspect is the spool according to any one of the first to sixth aspects, wherein the fishing line locking portion is movable in the radial direction of the bobbin trunk.
[0019]
In this case, for example, the fishing line locking portion is urged outward by a spring member or the like, or the fishing line locking portion can be moved forward and backward in the radial direction of the bobbin trunk by forming a screw on the locking pin. With this configuration, the fishing line can be easily locked in a state where the fishing line locking portion protrudes outward. Further, by winding the fishing line around the bobbin trunk in a state where the fishing line locking portion does not protrude outward, it is difficult to make a significant change in the bobbin shape.
[0020]
The spool according to the invention 8 is the spool of any one of the inventions 1 to 7, wherein the outer diameter of the bobbin trunk is 40% or more of the outer diameter of the flange.
[0021]
In this case, since the bobbin trunk is shallow, even when a thin fishing line is wound around the spool, it is difficult to cause winding rods.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
A dual-bearing reel employing an embodiment of the present invention is a low profile type reel for bait casting, as shown in FIGS. The dual-bearing reel includes a reel body 1, a handle assembly 2 for rotating a spool disposed on the side of the reel body 1, and a spool for spooling a spool that is rotatably and detachably mounted inside the reel body 1. 4 is provided. On the reel body 1 side of the handle assembly 2, a star drag 3 for drag adjustment is provided.
