Since the spacer used in the double-bearing type reel for fishing of Patent Document 1 can change the spool capacity by attaching spools of different sizes to one reel body, the situation response power at the fishing ground This has a certain effect on reducing the number of reels carried while maintaining the above.
However, since the spacer is a metal-made special part that is attached to the reel body by screwing it to the side plate or screwing it to a cover fixed to the side plate, the manufacturing cost increases and the weight increases. Also, the reel body side to which the spacer is attached needs to have a special shape so that the spacer can be attached, so that the versatility is poor, and a tool is required and labor is required for attaching and detaching work, etc. Because of this problem, there is room for improvement, particularly from a practical point of view.

  Therefore, in view of the situation described above, the present invention intends to solve the problem that the number of reels to be carried can be reduced while maintaining the ability to cope with the situation at a fishing spot. It is a point to provide a highly practical fishing double bearing type reel spacer and a fishing double bearing type reel provided with this spacer.

  A fishing double bearing type reel spacer according to the present invention is a fishing double bearing type reel in which a spool is rotatably supported by a reel body. A detachable spacer used in a state of being fitted along the inner surface of the spool, and in a state of being fitted to the frame, forming a minute gap facing the outer peripheral surface of the spool having a small flange outer diameter. It has an annular shape with a peripheral surface formed.

According to such a configuration, when a spool having a small flange outer diameter is used, the inner circumferential surface of the spacer is opposed to the outer circumferential surface of the flange of the spool to form a minute gap, so that the fishing line enters the gap. Therefore, there is no problem in winding and releasing the fishing line.
Therefore, spools with different sizes can be mounted on a single reel body. For example, when a spool with a small flange outer diameter is mounted, the inertia moment of the spool is small, so the device is small and light. The number of reels to be carried can be reduced while maintaining the situation response power at the fishing ground, such as being able to send out the pseudo bait with a light force.
In addition, since the spacer is annular, it is low cost and light weight, especially when made of synthetic resin, and can be easily used by being fitted to the frame without using a tool.
Furthermore, since the spacer is fitted along the inner peripheral surface of the frame facing the outer peripheral surface of the flange at both ends of the spool, it is not necessary to make the reel body side to which the spacer is attached into a special shape. Versatility can be improved.

In this case, it is preferable that a stopper portion that protrudes radially outward and stops against the axial inner surface of the frame is provided on the axially inner portion of the outer peripheral surface.
According to such a configuration, when the spacer is fitted to the frame from the inner side in the axial direction, the stopper is abutted against the inner surface in the axial direction of the frame to be positioned in the axial direction, and the outer side in the radial direction in a flange shape. The spacer can be easily removed by operating the stopper that protrudes toward the center.

Moreover, it is preferable to form a plurality of slits extending in the radial direction on the outer surface in the axial direction.
According to such a configuration, the axially outer portion of the spacer formed with a plurality of slits extending in the radial direction is easily deformed in the radial direction, so that the work of fitting along the inner peripheral surface of the frame is further facilitated. Become.

Furthermore, it is preferable that a circumferential groove is formed in the axially intermediate portion of the outer peripheral surface and an O-ring is attached to the circumferential groove.
According to such a configuration, even if the outer diameter of the spacer is reduced, the spacer can be stably held by the frame by the friction between the viscoelastic O-ring and the inner peripheral surface of the frame. The attachment / detachment work can be performed more easily.

  A fishing double bearing type reel according to the present invention includes the fishing double bearing type reel spacer.

  As described above, according to the double-bearing type reel spacer for fishing according to the present invention and the double-bearing type reel for fishing provided with this spacer, the number of reels to be carried can be maintained while maintaining the situation response force at the fishing spot. The simple structure of attaching and removing the annular spacer to the frame can be reduced, it is low cost and light weight, high versatility, and the spacer can be easily attached and removed. There is a remarkable effect that the sex can be greatly improved.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and all the embodiments satisfying the requirements described in the claims of the utility model registration. Is included.
In the present specification, the direction of the rotation axis of the spool (see arrow A in the figure) (the axial direction of the spool shaft) is referred to as the axial direction.

Embodiment 1 FIG.
As shown in FIG. 1, a double-bearing reel (bait casting reel) 1 for fishing supports a spool 3 around which a fishing line is wound by a reel body 2 (spool shaft 8) so as to be rotatable around a rotation axis A. When the handle 9 is turned, the spool 3 rotates in the fishing line winding direction.

Here, the spool 3 mounted on the reel body 2 has a small outer diameter of the flanges 5 and 5 at the front and rear ends in the axial direction, and the inner peripheral surfaces 5A and 5A of the flanges 5 and 5 Since the gap between the peripheral surfaces 7A and 7A is large, along the inner peripheral surfaces 7A and 7A of the frames 7 and 7 facing the outer peripheral surfaces 5A and 5A of the flanges 5 and 5 at both ends of the spool 3 in order to fill the gap. The annular spacers 11 and 11 according to the first embodiment of the present invention are fitted.
By the spacers 11 and 11, the gaps between the inner peripheral surfaces 11A and 11A of the spacers 11 and 11 and the outer peripheral surfaces 5A and 5A of the flanges 5 and 5 at the axial front and rear ends of the spool 3 become minute gaps G and G. Since the fishing line does not enter these minute gaps G and G, no trouble occurs when the fishing line is wound or released.

Here, the annular spacer 11 is formed of, for example, a synthetic resin such as polyacetal, polypropylene, or ABS. As shown in FIGS. 1B and 2, the annular spacer 11 has a radially outer side at an axially inner portion of the outer peripheral surface 11B. A stop portion 12 is provided so as to protrude and stop against the axial inner surface 7B of the frame 7.
Therefore, when the spacer 11 is fitted to the frame 7 from the inside in the axial direction as shown in FIG. 2, the stopper 12 is abutted against the axial inner surface 7B of the frame 7 to be positioned in the axial direction. The spacer 11 can be easily removed by operating the stopper 12 that protrudes radially outward.

  When the spacer 11 is removed, the spool 4 having a large flange outer diameter can be mounted as shown in FIG. 3, and when the spool 4 is mounted, the flange 6 at the front and rear ends in the axial direction of the spool 4 can be mounted. , 6 and the outer peripheral surfaces 6A, 6A of the frames 7, 7 are opposed to each other so that a small gap is formed, so that the fishing line does not enter the gap, so that the fishing line is wound or released. There will be no malfunctions.

According to the above configuration, spools 3 and 4 having different sizes can be mounted on one reel body 2 and used. For example, when a spool 3 having a small flange outer diameter is mounted, Since the moment of inertia of the spool 3 is small, the number of reels to be carried can be reduced while maintaining the situation response force at the fishing ground, such as being able to send out small and light devices and pseudo baits with a light force.
Further, since the spacer 11 is an annular ring made of synthetic resin, it is particularly low cost and light weight, and can be easily used by being fitted to the frame 7 without using a tool.
Further, since the spacers 11 and 11 are fitted along the inner peripheral surfaces 7A and 7A of the frames 7 and 7 facing the flange outer peripheral surfaces 5A and 5A at both ends of the spool 3, the spacers 11 and 11 are attached. Since it is not necessary to make the reel body 2 side a special shape, versatility can be improved.

Embodiment 2. FIG.
In the annular spacer 11 according to the second embodiment of the present invention shown in FIG. 4, a plurality of slits 13, 13,.
Therefore, since the axially outer portion of the spacer 11 is easily deformed in the radial direction, the work of fitting along the inner peripheral surface 7A of the frame 7 is further facilitated.
In addition, since the structure is easily deformed in the radial direction as described above, the protrusions 14 having an outer diameter larger than the inner diameter of the inner peripheral surface 7A of the frame 7 can be formed and firmly attached to the frame 7. For this reason, it is possible to make the structure easy to fit and hard to come off.

Embodiment 3 FIG.
In the annular spacer 11 according to the third embodiment of the present invention shown in FIG. 5, a circumferential groove 15 is formed in an axially intermediate portion of the outer circumferential surface 11B, and nitrile rubber (NBR) is formed in the circumferential groove 15. An O-ring 16 made of fluorine rubber (FPM) or silicone rubber (MVQ) is attached.
Therefore, even if the outer diameter of the spacer 11 is reduced, the spacer 11 is stabilized by the frame 7 by the friction between the O-ring 16 and the inner peripheral surface 7A of the frame 7 in a state where the O-ring which is a viscoelastic body is deformed. The spacer 11 can be attached and detached more easily.

Embodiment 4 FIG.
The annular spacer 11 according to the fourth embodiment of the present invention shown in FIG. 6 has a flange shape as shown in FIGS. 1, 2, 4 and 5 which are the first to third embodiments, and is radially outward. As shown in FIG. 6 (b), there is no projecting stop 12 and the brake housing 10 is removed, and the spacer 11 is fitted along the inner peripheral surface 7 A of the frame 7 from the outside in the axial direction. It is made into the shape which it is easy to mount | wear as a taper surface which chamfered the corner | angular part of the outer diameter part of axial direction inner surface 11D. The spacer 11 may have a rectangular cross section without forming such a tapered surface.

According to the double bearing type reel spacer 11 for fishing according to the first to fourth embodiments of the present invention as described above, it is suitable for, for example, a plurality of use models and a plurality of use spools of a double bearing type reel for fishing. Since it is only necessary to provide an annular light weight and simple spacer, it is possible to provide a very versatile and practical fishing double-bearing reel that meets the needs of the field.
Further, by using the annular spacer 11 as in the present invention to reduce the diameter, weight, and shallow groove of the spool, it is possible to greatly reduce the weight and improve the performance.
For example, as a result of an experiment in which a 35 mm diameter spool is replaced with a 32 mm diameter spool and an annular spacer of the present invention, it becomes possible to use a thinner fishing line than a 35 mm diameter spool, and it is lighter and has a small mechanism or pseudo It became possible to throw bait easily and far away. In addition, the small and light weight spool has a small moment of inertia during fishing line discharge, so backlash (tangled trouble) due to over-rotation is less likely to occur.

  In the above description, the case where the annular spacer 11 is made of a synthetic resin has been shown. However, the present invention is not limited to such a case, and the annular spacer 11 is made of an aluminum alloy or a magnesium alloy. It may be made of a light alloy such as, or other metal.
