Description

  The present invention relates to a spool, and more particularly to a spinning reel spool that is provided so that a fishing line is fed forward and is movable back and forth with respect to a reel body, and the fishing line is wound around an outer periphery.

Generally, a spinning reel includes a reel body, a rotor that is rotatably supported by the reel body, and a spool that is disposed in front of the rotor and on which a fishing line is wound around an outer periphery. Such a spool comes into contact with the bobbin trunk around which the fishing line is wound, the front flange part provided at the front end part of the bobbin winder part with a larger diameter than the bobbin winder part, and the front end part of the front flange part. A front flange fixing member mounted along the inner periphery of the bobbin trunk, and a skirt provided at the rear end of the bobbin trunk with a larger diameter than the bobbin trunk. In this type of spool, a storage space for storing the drag plate (friction part) of the drag mechanism that brakes the rotation of the bobbin trunk is formed in the inner periphery of the bobbin trunk, and is stored from the front. A waterproof member for preventing water or the like from entering the interior of the space is disposed between the front flange fixing member and the pressing member (knob portion) of the drag mechanism (for example, see Patent Document 1).
JP 2000-139286 A

  Since the conventional waterproofing member is disposed between the front flange fixing member mounted along the inner periphery of the bobbin trunk and the pressing member of the drag mechanism, the waterproofing member must be formed to have a large diameter. However, for this reason, it is necessary to reinforce the waterproof member itself by providing a metal disk member inside the elastic resin lip member, which may increase the manufacturing cost of the waterproof member. Accordingly, it is conceivable to extend a small-diameter storage wall portion that generates a storage space in which the drag plate of the drag mechanism is stored, and to attach a waterproof member to the inner peripheral portion of the storage wall portion. In this case, since the inner diameter of the storage wall portion is smaller than the inner diameter of the front flange fixing member mounted along the inner peripheral portion of the bobbin trunk portion, the waterproof member can be formed in a small diameter, Therefore, the waterproof member can be formed only with an inexpensive elastic resin lip member.

  As the conventional spool, a shallow groove spool in which the outer diameter of the bobbin trunk portion is formed large and the outer diameter of the front flange portion is formed small for winding a thin fishing line is known. In such a shallow groove spool, the outer diameter of the bobbin trunk is formed large, so that the inner peripheral part of the bobbin trunk is formed thick, which may increase the weight of the entire spool. Therefore, it is conceivable to reduce the weight of the entire spool by cutting out the inner peripheral portion of the bobbin trunk portion by cutting to form a hollow meat stealing portion.

  However, in particular, in a spool in which the storage wall portion is extended forward in order to attach a waterproof member having a small diameter, a space between the inner peripheral portion of the bobbin trunk and the outer peripheral portion of the storage wall portion is formed to form a meat stealing portion. When cutting the storage wall, the storage wall extends long forward, so that the cutting chips generated during the cutting process stay between the inner periphery of the bobbin trunk and the outer periphery of the storage wall. Therefore, it is very difficult to cut the meat stealing portion.

  An object of the present invention is to make a spool of a spinning reel waterproof with an inexpensive structure and to reduce the weight of the entire spool in an easy process.

  A spinning reel spool according to a first aspect of the present invention is a spinning reel spool that feeds fishing line forward and is movable back and forth with respect to the reel body, and includes a bobbin trunk, a front flange, a front flange fixing member, and a drag. A mechanism and a waterproof member are provided. The bobbin trunk includes a cylindrical portion around which the fishing line is wound, a disc portion extending inward from the inner peripheral portion on the rear end side of the cylindrical portion, and a cylindrical portion protruding forward from the disc portion. And a storage wall portion that forms a storage space. The front flange portion is an annular member that is provided at the front end portion of the cylindrical portion and has an outer diameter larger than the outer diameter of the cylindrical portion. The front flange fixing member extends inwardly from the inner peripheral portion of the front collar at a front flange portion that is mounted so as to contact the front end portion of the front flange portion, and at a position forward of the front end portion of the storage wall portion. Part. The drag mechanism includes a knob portion at least a part of which is disposed on the inner peripheral side of the front flange fixing member, and a friction portion that is disposed in the storage space and is pressed by the rearward movement of the knob portion. This is a mechanism for braking the rotation in the yarn unwinding direction. The waterproof member is disposed between the front flange fixing member and the drag mechanism, and both end surfaces are held in contact with the inner side surface of the extending portion and the outer side surface of the knob portion.

  In this spool, the front flange fixing member has an extending portion extending inward from the inner peripheral portion of the front collar portion at a position in front of the front end portion of the storage wall portion, and the waterproof member is the front flange fixing member. The both end faces are in contact with and sandwiched between the inner surface of the extending portion and the outer surface of the knob portion. Here, since the waterproof member is arranged so that the front end surface is in contact with the inner surface of the extending portion, the waterproof member can be formed in a small diameter, and therefore the waterproof member is made of an inexpensive elastic resin. It can be formed with only a lip member. Here, since the waterproof member is not attached to the inner peripheral portion of the storage wall portion, it is not necessary to extend the storage wall portion forward. For this reason, when forming a meat stealer for weight reduction between the inner peripheral part of the cylindrical part and the outer peripheral part of the storage wall part, the cutting chips generated when cutting are generated in the bobbin trunk part. Since it becomes difficult to stay between an inner peripheral part and the outer peripheral part of a storage wall part, it becomes easy to cut a meat stealing part. Accordingly, the inside of the spool can be waterproofed with an inexpensive configuration, and the weight of the entire spool can be reduced by an easy process.

  The spool according to a second aspect of the invention is the spool of the first aspect, wherein the extension part is formed in a cylindrical shape on the inner peripheral part of the plate-like part and a plate-like part extending inward from the inner peripheral side of the front collar part on the inner side surface And a cylindrical portion with which one end face of the waterproof member can come into contact. In this case, since the cylindrical part which can contact the one end surface of a waterproof member is formed, a waterproof member can be made to contact reliably and, therefore, waterproofness can be improved.

  The spool according to a third aspect is the spool according to the second aspect, wherein the cylindrical portion is formed such that the inner side surface is positioned substantially the same as the inner side surface of the storage wall portion or outside the inner side surface of the storage wall portion. In this case, since the front of the storage wall can be reliably covered by the waterproof member, the waterproof property can be further improved.

  The spool according to a fourth aspect of the present invention is the spool of the first or second aspect, wherein the extending portion is formed such that the inner side surface is substantially the same as the inner side surface of the storage wall portion or outside the inner side surface of the storage wall portion. . In this case, since the front of the storage wall can be reliably covered with the waterproof member, the waterproof property can be further improved.

  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 collar portion is formed so as to be inclined forward so as to cover a portion that is the outermost diameter position of the knob portion. In this case, the front rod portion is formed so as to incline forward, so that the fishing line is less likely to be caught by the knob portion.

  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 cylindrical portion has a female thread portion formed on the inner surface on the front end side. The front collar portion has a cylindrical inner cylinder portion that extends rearward from the rear surface of the inner peripheral portion and the outer peripheral surface is attached to the inner side surface of the cylindrical portion. The inner cylinder part has a male thread part formed on the outer surface and screwed into the female thread part. In this case, the front flange fixing member can be easily attached and detached.

  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 cylindrical portion has a male thread portion formed on the outer surface on the front end side. The front collar portion has a cylindrical outer tube portion that extends rearward from the rear surface of the inner peripheral portion, and the inner peripheral surface is attached to the outer surface of the cylindrical portion. The outer cylinder part has an internal thread part formed on the inner surface and screwed into the external thread part. In this case, the front flange fixing member can be easily attached and detached.

  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 waterproof member is a synthetic resin lip member having elasticity. In this case, the inside of the spool can be waterproofed with an inexpensive configuration by a relatively inexpensive lip member.

  The spool according to the ninth aspect is the spool according to any one of the first to eighth aspects, wherein the waterproof member is fixed to the outer peripheral surface of the knob portion by a retaining ring member. In this case, the waterproof member can be fixed with a simple configuration.

  A spool according to a tenth aspect of the present invention is the spool according to any one of the first to ninth aspects, wherein the front flange fixing member is formed to protrude to the inner peripheral side of the extension portion, and further includes a protrusion portion that can contact the front surface of the waterproof member. is doing. In this case, the waterproof property can be further improved by bringing the front surface of the waterproof member into contact with the rib as the protruding portion.

  A spool according to an eleventh aspect of the invention is the spool according to the tenth aspect, wherein the protruding portion is formed by cutting out a part and has a locking portion for locking the tool. In this case, the assemblability can be improved by providing a slit as a locking portion for locking the tool.

  According to the present invention, in the spinning reel spool, the front flange fixing member has an extending portion extending inward from the inner peripheral portion of the front collar portion at a position in front of the front end portion of the storage wall portion, The waterproof member is disposed between the front flange fixing member and the drag mechanism, and both end surfaces are held in contact with the inner side surface of the extension portion and the outer side surface of the knob portion, so that the inside of the spool can be constructed with an inexpensive configuration.

And the outer surface of the pressing member 61b of the knob portion 61 are in contact with and held between. The waterproof member 80 is a synthetic resin lip member having elasticity such as NBR. The waterproof member 80 is mounted so that the dish-shaped lip on the outer peripheral portion faces the front side.

  Next, the operation and operation of the reel will be described.

  At the time of casting, the bale arm 44 is reversed to the yarn releasing posture. As a result, the first bail support member 40 and the second bail support member 42 swing. In this state, the fishing rod is cast while hooking the fishing line with the index finger of the hand holding the fishing rod. The fishing line is then released vigorously due to the weight of the device. If the handle 1 is rotated in the fishing line winding direction after the device has landed, the rotor 3 is rotated in the fishing line winding direction by the rotor driving mechanism 5 and the bail arm 44 is returned to the fishing line winding position by a bail reversing mechanism (not shown). Since the reverse rotation of the rotor 3 is prohibited, the release of the fishing line stops.

  When winding the fishing line, the handle 1 is rotated in the fishing line winding direction. Then, the rotation is transmitted to the rotor 3 via the face gear 11 and the pinion gear 12, and the rotor 3 rotates. When the rotor 3 rotates, the fishing line guided by the line roller 41 is wound around the spool 4.

  In such a spinning reel, the front flange fixing member 9 includes a cylindrical inner cylinder portion 9c extending from the inner rear portion of the front flange portion 9a to a position ahead of the front end portion of the storage wall portion 16g, and the inner cylinder portion 9c. And an extending portion 9d extending inward from the rear end portion. Further, the waterproof member 80 is disposed between the front flange fixing member 9 and the pressing member 61b of the knob portion 61 of the drag mechanism 60, and both end faces of the inner surface of the cylindrical portion 9g of the extending portion 9d and the knob portion 61 are provided. It is held in contact with the outer surface of the pressing member 61b.

  Here, since the waterproof member 80 is disposed so that the front end surface is in contact with the inner side surface of the cylindrical portion 9g of the extending portion 9d, the waterproof member 80 can be formed in a small diameter. 80 can be formed only by an inexpensive elastic resin lip member. Furthermore, since the waterproof member 80 is not attached to the inner peripheral portion of the storage wall portion 16g, it is not necessary to extend the storage wall portion 16g forward. For this reason, when the meat stealing part 100 for weight reduction is formed between the inner peripheral part of the cylindrical part 16a and the outer peripheral part of the storage wall part 16g, the cutting chips generated when cutting are formed in the cylinder. Since it becomes difficult to stay between the inner peripheral part of the shape part 16a and the outer peripheral part of the storage wall part 16g, it becomes easy to cut the meat stealing part 100. Accordingly, the inside of the spool can be waterproofed with an inexpensive configuration, and the weight of the entire spool can be reduced by an easy process.
