DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel body, and more particularly to a reel body of a spinning reel for winding a fishing line by rotating a rotor.

[0002]

2. Description of the Related Art Generally, a spinning reel includes a reel body having a mechanism housing space therein, a rotor disposed at a front part of the reel body and rotatably supported by the reel body.
A spool for winding the bobbin disposed in front of the rotor and supported by the reel body so as to be able to advance and retreat. A handle is attached to the reel body, and in the mechanism storage space,
Movement mechanisms such as a rotation transmission mechanism for transmitting the rotation of the handle to the rotor, an oscillating mechanism for moving the spool forward and backward in conjunction with the rotation of the handle, and an operation unit (stopper shaft) for a reverse rotation prevention mechanism for preventing reverse rotation of the rotor It is stored.

The reel body has a reel body in which a mechanism housing space having an opening on the side is formed, and a lid member detachably mounted on the reel body so as to cover the opening of the reel body. I have. A front portion of the reel body is disposed in a recess formed at a rear portion of the rotor, and a rotation support portion that supports a rotation shaft of the rotor is formed at the front portion.

[0004] In addition, a flange portion is provided at the front of the reel body so as to close the concave portion in order to prevent foreign substances such as fishing line and sand from entering the concave portion. The flange portion is formed at the rear portion of the rotation support portion and substantially flush with the rear end surface of the concave portion. Japanese Unexamined Utility Model Publication No. 4-43016 discloses a reel body in which first and second flange portions integrally formed on a reel body and a lid member constitute the flange portion. The first and second flange portions disclosed in the above publication are integrally formed on the reel body and the lid member so as to cover the concave portions, respectively. By dividing the flange portion into two in this way, the strength of the lid member can be maintained, and when both ends of the handle shaft are supported by the reel body and the lid member, a driving portion due to deformation of the lid member Wear can be prevented, and the durability can be improved. Also, by dividing the flange,
The face gear constituting the rotation transmitting mechanism can be arranged as far as possible in front of the mechanism housing space, and the size of the reel body can be reduced.

[0005]

In the reel body of the conventional spinning reel, the flange portion is divided into two, a first flange portion and a second flange portion, and the first and second flange portions are formed on the reel body and the lid member. Since each is integrally formed, liquid such as seawater easily enters the mechanism housing space from the gap between the first and second flange portions. When a corrosive liquid enters the mechanism storage space, the internal mechanism is rusted and the rotation efficiency of the handle is likely to decrease.

Therefore, conventionally, a high-viscosity grease is applied to the mechanism inside the mechanism housing space on the assumption of infiltration of a liquid to make it difficult to remove the grease. However, the application of such a high-viscosity grease hinders an improvement in the winding efficiency of the handle. In addition, when seawater enters, even if grease is applied, precipitates such as salt crystals are generated, and the precipitates may be caught between gears or the like, thereby deteriorating the rotational feeling.

SUMMARY OF THE INVENTION An object of the present invention is to provide a spinning reel having two divided flange portions.
An object of the present invention is to improve the winding efficiency of a handle and to suppress a decrease in rotational feeling.

[0009] In the reel body of this spinning reel,
Since the seal member is interposed between the divided first and second flange portions, the liquid does not easily enter the mechanism housing space from between the two flange portions. Therefore, low-viscosity grease can be used for the mechanism in the mechanism storage space.
Therefore, the resistance due to the grease is reduced, and the winding efficiency of the handle can be improved. In addition, since the liquid does not easily enter the mechanism housing space, the amount of deposits generated when the liquid dries is reduced, the deposits are less likely to be caught between gears and the like, and a decrease in rotational feeling can be suppressed. .

Between the positioning washer 54 and the bearing 57, a seal ring 91 made of an elastic material is mounted so as to contact the inner ring and the outer ring of the bearing 57 and the bearing mounting portion of the spool 4. The seal ring 91 is a washer-shaped member, and is provided to prevent liquid from entering the drag mechanism 60 from the rear of the spool 4.

[Structure of Drag Mechanism] The drag mechanism 60
This mechanism is mounted between the spool 4 and the spool shaft 15 to apply a drag force to the spool 4. As shown in FIG. 6, the drag mechanism 60 includes a knob 61 for manually adjusting the drag force, and a spool 4 by the knob 61.
And a friction portion 62 composed of a plurality of disks pressed to the sides.

The knob 61 includes a first member 63 provided on the spool shaft 15 so as to be non-rotatable and movable in the axial direction, and a second member disposed axially forward of the first member 63 and screwed to the spool shaft 15. 64 and a sound generating mechanism 65 mounted between the first member 63 and the second member 64. The first member 63 is a flanged cylindrical member having a cylindrical portion 63a and a ring-shaped flange 63b having a larger diameter than the cylindrical portion 63a. An oval locking hole 66 is formed in the inner peripheral portion of the cylindrical portion 63a to lock the spool shaft 15 so that it cannot rotate. The rear end surface of the cylindrical portion 63a of the first member 63 is
Abut. Between the cylindrical portion 63a of the first member 63 and the inner peripheral surface of the spool ring collar 55, a friction portion 6
A seal plate 71 for preventing liquid from entering the two sides is mounted. The seal plate 71 is, for example, a seal member obtained by outsert molding an NBR dish-shaped elastic member around a stainless steel ring member, and has a lip on an outer peripheral portion. The seal plate 71 is urged leftward in FIG. 6 by a snap ring 79. Seal plate 71
6, a ring-shaped projection 71c is formed. The projecting portion 71c is connected to a cover member 68 described later.
To prevent the liquid from entering the inner peripheral side.

The second member 64 is provided to face the first member 63 and to be rotatable relative to the first member 63. The second member 64 has a knob main body 67 arranged in front of the first member 63 in the direction of the spool shaft 15, and a distal end fixed to an outer peripheral portion of the knob main body 67, and the first member 63 is rotatably housed therein. And a cover member 68 to be used. The knob main body 67 is a disk-shaped member, and has a substantially trapezoidal knob 67a protruding forward on the front surface. Knob body 6
A nut 69 screwed to the tip of the spool shaft 15 is mounted inside the inside 7 so as to be non-rotatable and axially movable.
A coil spring 70 is arranged in a compressed state around the spool shaft 15 between the second member 64 and the nut 69.

The cover member 68 is a cylindrical member having a bottom, and the cylindrical portion 63a of the first member 63 penetrates the bottom. The projection 71c of the seal plate 71 is in contact with the bottom. The cylindrical portion 68 a of the cover member 68 is screwed to the outer peripheral surface of the knob main body 67. A washer-shaped seal ring 72 is mounted between the bottom 68b of the cover member 68 and the rear end surface of the cylindrical portion 63a of the first member 63. Further, an O-ring 73 is mounted between the tip of the cylindrical portion 68 a of the cover member 68 and the knob main body 67.
Each of the seal ring 72 and the O-ring 73 is an elastic member made of, for example, NBR. The seal ring 72 and the O-ring 73 prevent liquid from entering into the inside from the gap between the knob body 67 of the first member 63 and the second member 64. It is provided in. When the liquid enters from this gap, even if the seal plate 71 is provided, water enters the friction portion 62 through the gap between the first member 63 and the spool shaft 15, and the friction portion 62 gets wet and the drag force fluctuates. May be.

The friction portion 62 includes a first disk 101 that contacts the first member 63, a second disk 102 that contacts the first disk 101 with a felt member interposed therebetween, and a second disk 102 that contacts the second disk 102 with a felt member interposed therebetween. And a drag sound generating mechanism 103. The inner periphery of the first disk 101 is locked to the spool shaft 15 and rotates together with the spool shaft 15. The outer periphery of the second disk 102 is the spool 4
And rotates together with the spool 4. The drag sound generating mechanism 103 emits sound when the spool shaft 15 and the spool 4 are relatively rotated, that is, when the drag is operated.

[Operation and Operation of Reel] In this spinning reel, the bail arm 40 is tilted to the line releasing position when the line is fed out during casting or the like. As a result, the fishing line is sequentially fed out from the leading end side of the spool 4 by its own weight. At the time of yarn winding, the bail arm 40 is returned to the yarn winding posture. When the handle assembly 1 is rotated in the line winding direction, the operation is automatically performed by a bale reversing mechanism (not shown). The rotational force of the handle assembly 1 is transmitted to the pinion gear 12 via the master gear shaft 10 and the master gear 11. The torque transmitted to the pinion gear 12 is transmitted from its front portion to the rotor 3 and is also transmitted to the oscillating mechanism 6 by the intermediate gear 23 meshing with the pinion gear 12. As a result, the rotor 3 rotates in the line winding direction and the spool 4 reciprocates back and forth.

When fishing, waves and the like may hit the reel and cause the reel to get wet. Again, in this case,
Since the seal plate 71, the seal ring 72, and the O-ring 73 are mounted on the drag mechanism 60 and the seal ring 91 is mounted on the spool 4, water does not easily enter the friction portion 62 from the front or rear. For this reason, once the drag force is adjusted, the drag force is less likely to fluctuate due to water wetting.

Further, seal rings 18a, 18a are provided in gaps between the reel body 2a and the moving member, the fixed member and the constituent members.
b, shaft seal 34, liquid gasket 80, waterproof seal 8
1, seal ring 82, shaft seal 85, O-ring 86,
Since the seal member such as the sheet packing 87 is provided, it is possible to prevent the liquid from entering the internal mechanism storage space 26. For this reason, it becomes difficult for seawater and the like to enter inside, and salt crystals hardly precipitate in gears, guides, bearings, and the like. Therefore, it is not necessary to apply grease having a high viscosity to the inside, the deposits are less likely to be caught between the gears and the rolling elements and the like, and a decrease in the rotational feeling can be suppressed.

[Other Embodiments] (a) In the above embodiment, a front drag type spinning reel was described as an example, but a rear drag type spinning reel, a spinning reel having no drag, or a lever drag type spinning reel. The present invention can be applied to the reel bodies of all spinning reels.

(B) In the above embodiment, the master gear shaft (handle shaft) 10 is connected to the reel body 2a and the lid member 2d.
However, it may be supported by only one of them.

[0052]

According to the present invention, since the seal member is interposed between the divided first and second flange portions,
The liquid is less likely to enter the mechanism housing space from between the two flange portions. Therefore, low-viscosity grease can be used for the mechanism in the mechanism storage space. Therefore, the resistance due to the grease is reduced, and the winding efficiency of the handle can be improved. In addition, since the liquid does not easily enter the mechanism storage space, the amount of precipitates generated when the liquid dries is reduced, and the precipitates are less likely to be caught between gears and the like.
A decrease in rotational feeling can be suppressed.
