Description

[Detailed explanation of the invention] (a) Purpose of the invention [Field of industrial application] The invention is based on a system in which a spool shaft to which a spool is fixed is rotatably supported by the main body, and a spool shaft is attached to the rear end of the spool shaft. The present invention relates to a drag mechanism housing portion of a spinning reel for rear drag fishing, in which the drag mechanism is provided on the rear side of the main body.

The drag mechanism described above includes a drag washer on the body side that is non-rotatably supported by the main body, and a spool shaft that is non-rotatably supported by the spool shaft. The side drag washers are stacked in the axial direction, and by pressing them with a control screw via a drag spring, the frictional force generated between the drag washers can be adjusted to arbitrarily adjust the rotational load of the spool. Configurable.

[Conventional technology]

The above-mentioned conventional drag mechanism stores drag washers on both the main body side and the spool shaft side, including the rear end of the spool shaft, and a drag spring, and the drag mechanism storage part into which the control screw is screwed is integrated with the main body. In addition, in order to reduce the weight of the reel, it is now common to mold the main body from a synthetic resin material.

[Problem that the invention attempts to solve]

However, according to the above-mentioned conventional storage section, when drag force is generated, when heat is generated due to friction between the drag washers, the drag washers may dig into the support section of the storage section, which is made of resin with poor heat resistance, or click on the spool shaft. When fixed, the click will fit into the shaft hole of the main body, so
In such a case, the heat generated by the rotation of the click will cause the shaft hole of the main body to become abnormally deformed and worn, making it easy to become loose.As a result, if each drag washer becomes tilted due to biting, the preset distance between the same washers may be changed. If the friction force is not obtained, it becomes impossible to make fine adjustments to the drag force, or the click rotates eccentrically, causing problems in meshing with the clicker, causing the click noise to no longer be generated, or the spool shaft There were problems such as the drag mechanism was often lost as a result of hindering rotation.

The present invention solves the above-mentioned problems of the conventional art by using the configuration described in detail below.

(B) Structure of the invention [Means for solving the problem] A spool shaft to which a spool is fixed is rotatably supported by the main body, and a drag mechanism is attached to the rear end of the main body in relation to the rear end of the spool shaft. In the drag mechanism storage part of the rear drag spinning reel provided in the spool shaft, a click fixed to the spool shaft;
The drag mechanism storage member is approximately cup-shaped and made of aluminum or other metal material so that the drag washers on both the main body side and the spool shaft side that are externally mounted on the click and the drag springs that are interposed between the washers and the control screw can be housed. The outer peripheral surface and the opening edge are provided with an appropriate number of anti-rotation protrusions and a protrusion for regulating the rotation of the drag knob, and a mounting tube is protruded from the base to provide a fitting connection provided at the rear of the main body. The above-mentioned mounting tube is fitted into the mounting hole of the base of the concave portion, and is non-rotatably fitted and fixed by the rotation preventing convex portion, and the above-mentioned click base is rotatably fitted into the mounting tube, and the click base is rotatably fitted into the mounting tube. A drag mechanism is built into the threaded part by screwing the above-mentioned control screw so that it can move forward and backward, and this prevents the drag washer from digging into the main body and uneven wear of the click fitting hole. It is possible to prevent this and maintain the drag function for a long period of time.

〔Example〕

As shown in FIGS. 1 to 3, a fitting recess 2 with a generally cup-shaped longitudinal section, which is oriented horizontally and opened rearward, is formed integrally with a base plate 2a and a peripheral wall 2b at the rear end of the main body 1. The substrate portion 2
A mounting hole 2c is formed through the center of a.

A drag mechanism storage member 4 for housing the drag mechanism 3 has dimensions that fit the fitting recess 2, has a substantially horizontal cup shape in vertical section, and is provided on a bottom wall 4a and protrudes from the periphery of the bottom wall 4a. A mounting cylinder 4c is formed integrally with the bottom wall 4a and protrudes outward from the center of the bottom wall 4a, and a retaining ring groove 4d is formed near the end of the mounting cylinder 4c. Furthermore, two anti-rotation protrusions 4e, 4e are provided on the outer surface of the peripheral wall 4b at long symmetrical positions in the axial direction, and a projection 4f is provided on one side of the opening edge of the peripheral wall 4b.
In addition, on the inner surface of the peripheral wall 4b, two drag washer fitting grooves 4g, 4g are provided at opposing positions and are long in the axial direction and extend to the opening edge.

The drag mechanism housing member 4 is integrally formed of aluminum or other metal material and has sufficient strength.

In this way, the drag mechanism storage member 4 is fitted into the fitting recess 2 of the main body 1, and after the mounting cylinder 4c is fitted into the mounting hole 2c, the retaining ring 5 is fitted into the retaining ring groove 4d. At the same time, the anti-rotation protrusions 4e are engaged with grooves 2d, which are long in the axial direction and are formed in advance in positions facing the inner surface of the peripheral wall 2b in the fitting recess 2. By fitting, the fitting is fixed in the fitting recess 2 in a non-rotatable manner.

Here, a cutout groove 2e is provided on one side of the opening edge of the fitting recess 2, and is engaged with the protrusion 4f of the drag mechanism storage member 4 and protrudes outward.

Further, the rear end portion of the spool shaft 6, which fixes a spool (not shown) that is rotatably supported in the main body 1 at the front end portion, is formed into an oval-shaped cross section or an arbitrary polygonal shape. Since the click 7 is fixed to the exterior, by rotatably fitting the cylindrical portion 7a provided at the base of the click 7 into the mounting tube 4c, the click 7 can be housed in the drag mechanism. It is projected into the member 4.

Here, the drag mechanism 3 is connected to the click 7.
The drag mechanism 3 is formed of a main body side drag washer 3a... including a spool shaft side drag washer 3b..., a drag spring 3c, a control screw 3d, and a drag knob 3e. It is installed inside the drag mechanism storage member 4.

As clearly shown in FIG.
..., 3b... are externally packaged in a stacked state in the axial direction, and the main body side drag washers 3a...
is arranged so as to be rotatable with respect to the click 7, and non-rotatable with respect to the drag mechanism storage member 4 by being engaged with its fitting groove 4g, while the spool shaft side drag washers 3b... 7, and rotatably relative to the drag mechanism housing member 4.

Also, the above control screw 3d and drag knob 3
e is integrated by meshing the teeth 3f and 3g provided on both sides and tightening with a tightening screw 3h, as clearly shown in FIGS. 1 and 4, and the screw of the control screw 3d. The control screw 3 is screwed into a threaded portion 4h formed on the inner surface of the peripheral wall 4b of the drag mechanism housing member 4 so as to be freely retractable.
The drag mechanism 3 is housed in the drag mechanism storage member 4 by interposing the drag spring 3c between the drag washer 3a and the drag washer 3a.

Further, a stopper boss 3j is protruded from the inner surface of the peripheral wall of the drag knob 3e, and when this comes into contact with the protrusion 4f of the drag mechanism storage member 4, the rotation of the drag knob 3e is restricted to one rotation.

In FIG. 1, reference numeral 7b indicates a tooth portion provided on the click 7 so as to be able to engage with a clicker (not shown).

[Effect of idea]

As explained above, since the drag mechanism storage section of the spinning reel according to the present invention is constructed, when the drag force is generated due to the frictional force between the drag washers 3a..., 3b..., heat is generated.
The drag mechanism storage member 4 in which the drag washers 3a on the main body side are engaged and installed is made of metal and has sufficient heat resistance, so the washers 3a do not bite into the member 4 and tilt. Since the click 7 is also fitted into the mounting tube 4c of the member 4, it can be prevented from being deformed and worn due to the heat generation, and therefore the original drag function can be maintained for a long period of time. Furthermore, the drag mechanism storage member 4 can be easily mass-produced by press working or die casting, and can be simply and easily assembled into the fitting recess 2 of the main body 1 by press-fitting. , it can be manufactured without much increase in cost compared to the conventional example.
