The brake mechanism is accommodated in the spool. The adjusting member is rotatably mounted on the spool shaft at a front side of the spool, and a braking force of the brake mechanism is changed according to the rotation of the adjusting member. Further, in patent document 1, a sealing member is provided to prevent a gap between the moisture self-regulating member and the spool from entering the brake mechanism.

Disclosure of Invention

[ problems to be solved by the invention ]

In patent document 1, moisture entering a gap between the self-regulating member and the spool easily reaches the sealing member. Since the moisture reaching the sealing member is more likely to intrude into the brake mechanism as the moisture amount increases, the moisture amount reaching the sealing member is preferably small.

In patent document 1, it is difficult for water entering the gap between the self-regulating member and the spool to be discharged to the outside. Therefore, for example, when the regulating member is removed from the spool shaft, moisture remaining in a gap between the regulating member and the spool may erroneously enter the inside of the spool.

The invention aims to prevent the water from entering into a winding reel from a gap between a self-adjusting member and the winding reel.

[ means for solving the problems ]

A spinning reel according to the present invention is a spinning reel for delivering a fishing line forward, comprising a reel body, a spool shaft extending in a forward and backward direction and supported by the reel body, a spool rotatably supported by the spool shaft, a braking mechanism disposed on an inner peripheral portion of the spool for braking rotation of the spool, and a waterproof structure having a wall portion facing the wall portion of the spool in an axial direction of the spool shaft, the wall portion being rotatably attached to a front end of the spool shaft with a gap therebetween, for regulating a braking force of the braking mechanism by rotation, the waterproof structure being provided on either one of the wall portion of the spool and the facing wall portion of the regulating member for suppressing intrusion of water into the interior of the spool, the waterproof structure having an annular protrusion protruding toward the wall portion 26 and , and a recess recessed portion recessed from the wall portion in a direction of the annular protrusion toward an outer side of the wall portion of the spool shaft, the waterproof structure being further recessed from the wall portion toward the outer side than the annular protrusion.

In this spinning reel, for example, when a waterproof structure is provided on the wall portion of the spool, moisture that enters the inside of the spool along the wall portion of the spool from the gap between the spool and the regulating member enters the annular recessed portion when crossing the annular recessed portion. When moisture along the wall of the spool passes over the annular recessed portion, the annular protruding portion suppresses the intrusion of moisture. That is, the annular recessed portion and the annular projecting portion can suppress the intrusion of moisture into the brake mechanism disposed inside the spool. In addition, in the case where the facing wall portion of the adjustment member is provided with the waterproof structure, the same effect as described above can be obtained with respect to the moisture from the gap between the take-up drum and the adjustment member along the wall portion of the adjustment member.

When the wall of the spool and the facing wall of the regulating member face each other in the front-rear direction, the annular recessed portion serves as a passage for water, and water introduced into the annular recessed portion moves downward along the inside of the annular recessed portion. The moisture moving in the annular recess flows out in a direction away from the center of the spool, and therefore the moisture is easily discharged to the outside.

Preferably, the annular concave portion is disposed at a radial distance from the annular convex portion. In this case, the intrusion of water into the spool can be effectively suppressed.

Preferably, the waterproof structure further includes an inclined portion that is inclined forward as it extends outward in the radial direction. In this case, the moisture entering from the gap between the take-up drum and the adjustment member is easily discharged to the outside.

Preferably, the spool further includes a cover portion extending forward from the wall portion and covering an outer peripheral portion of the opposing wall portion of the adjustment member. In this case, the penetration of moisture from the radial direction can be suppressed.

Preferably, the adjustment member further includes a cylindrical portion having an outer peripheral portion disposed to face the inner peripheral portion of the wall portion of the spool, and a seal member for sealing a gap between the inner peripheral portion of the wall portion of the spool and the outer peripheral portion of the cylindrical portion of the adjustment member. In this case, the amount of moisture reaching the sealing member is suppressed by the annular concave portion and the annular convex portion, and therefore, the sealing member can easily prevent the moisture from entering the inside of the spool.

Preferably, the waterproof structure is provided on both the wall portion of the spool and the opposing wall portion of the adjustment member, and in this case, the intrusion of water into the interior of the spool can be further suppressed .

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, the penetration of moisture into the interior of the spool from the gap between the regulating member and the spool can be suppressed.

The spool tube 4d is attached to the spool shaft 3 so as to be non-rotatable and detachable. The spool 4 and the brake mechanism 20 are detachably mounted on the spool shaft 3 via a spool tube 4 d. As shown in fig. 2, the bobbin tube portion 4d has a male screw portion 4f on the outer peripheral surface of the tip end.

The cover portion 4e extends in a cylindrical shape forward from the front wall portion 4b, and covers an outer peripheral portion of a later-described opposing wall portion 30b of the adjustment member 30, and the cover portion 4e and the front wall portion 4b are formed as bodies, and the cover portion 4e may be formed separately from the front wall portion 4 b.

The brake mechanism 20 is disposed on the inner peripheral portion of the spool 4 as shown in fig. 1, and brakes the rotation of the spool 4. Specifically, the brake mechanism 20 is housed inside the spool body 4a of the spool 4. The brake mechanism 20 has a plurality of friction members 20 a. Since the brake mechanism 20 has the same configuration as that of the conventional brake mechanism, detailed description thereof is omitted.

The adjusting member 30 is rotatably mounted on the front end of the spool shaft 3 with a gap from the spool 4. In the present embodiment, the adjustment member 30 is rotatably attached to the tip end of the spool shaft 3 via the spool tube 4 d. The braking force of the brake mechanism 20 is adjusted by rotation of the adjustment member 30.

As shown in fig. 2, the adjustment member 30 includes a handle body portion 30a, an opposing wall portion 30b, a cylindrical portion 30c, a handle portion 30d, a nut 30e, a spring member 30f, and a pressing member 30 g.

The handle body 30a is circular and is rotatably attached to the tip of the spool shaft 3 via a nut 30 e.

The facing wall portion 30b is formed with the handle body portion 30a, and extends in a ring shape and a plate shape from the handle body portion 30a to the outside in the diameter direction, the facing wall portion 30b faces the front wall portion 4b of the spool 4 in the axial direction, more specifically, the facing wall portion 30b is disposed in front of the front wall portion 4b at an interval in the axial direction from the front wall portion 4b, the outside in the diameter direction of the facing wall portion 30b is covered with the cover portion 4e of the spool 4, and the facing wall portion 30b has a gap in the diameter direction with the cover portion 4e, and the gap is opened forward.

The cylindrical portion 30c extends in a cylindrical shape rearward from the handle main body portion 30a, the cylindrical portion 30c is disposed so that an outer peripheral portion thereof faces an inner peripheral portion of the front wall portion 4b of the spool 4, the cylindrical portion 30c is formed in with the handle main body portion 30a, and a rear end portion of the cylindrical portion 30c contacts the seal member 50.

The handle portion 30d is an operation portion for performing a turning operation of the adjustment member 30. The handle portion 30d extends in the diameter direction and projects forward from the handle main body portion 30 a. The handle portion 30d is fixed to the front portion of the handle main body portion 30a by a screw member 32.

The nut 30e is housed in the inner peripheral portion of the handle main body 30a so as to be relatively non-rotatable with respect to the handle main body 30a and relatively movable in the axial direction.A female screw portion 30h is formed on the inner peripheral surface of the nut 30e, and the female screw portion 30h is screwed into the male screw portion 4f of the spool tube portion 4 d. thus, the nut 30e rotates together with the adjustment member 30 in accordance with the rotation of the adjustment member 30 and moves in the axial direction along the spool tube portion 4 d.

The spring member 30f is disposed between the nut 30e and the pressing member 30g in the axial direction. The spring member 30f is attached to the outer peripheral portion of the bobbin cylinder 4 d. The spring member 30f presses the pressing member 30g toward the plurality of friction members 20 a.

As shown in fig. 1, the pressing member 30g is disposed between the adjustment member 30 and the plurality of friction members 20a in the axial direction. When the adjustment member 30 is rotated, the nut 30e moves in the axial direction with respect to the bobbin cylinder 4d, and the force with which the spring member 30f presses the pressing member 30g changes. Thereby, the force with which the pressing member 30g presses the plurality of friction members 20a changes, and the braking force of the brake mechanism 20 changes.

The waterproof structure 40 is provided on any of the front wall portion 4b of the spool 4 and the opposing wall portion 30b of the adjustment member 30, and suppresses intrusion of water into the interior of the spool 4. in the present embodiment, the waterproof structure 40 is provided on the front wall portion 4b of the spool 4. the waterproof structure 40 suppresses intrusion of water entering from a gap between the cover portion 4e of the spool 4 and the opposing wall portion 30b of the adjustment member 30 into the interior of the spool 4 and further into the brake mechanism 20.

As shown in fig. 2 and 3, the waterproof structure 40 includes an annular convex portion 40a and an annular concave portion 40 b. Further, the waterproof structure 40 preferably further includes an inclined portion 40 c. The annular convex portion 40a, the annular concave portion 40b, and the inclined portion 40c are formed on the inner side in the diameter direction of the cover portion 4e and on the front side of the front wall portion 4 b.

The annular projection 40a projects in the axial direction from the front wall 4b of the take-up drum 4 toward the opposing wall 30b of the adjustment member 30, and is formed annularly in the circumferential direction. The annular projection 40a is formed to protrude from the inner edge of the front wall 4 b.

The annular recess 40b is recessed in a direction in which the front wall portion 4b of the spool 4 is separated from the opposing wall portion 30b of the self-regulating member 30, and is formed in an annular shape in the circumferential direction. In the present embodiment, the annular recess 40b is formed to be recessed in the axial direction from the front to the rear at a position axially opposite to the facing wall 30 b. The annular recessed portion 40b is formed radially outward of the annular projecting portion 40 a. The annular recessed portion 40b is preferably arranged at a radial distance from the annular projecting portion 40 a.

The inclined portion 40c is formed to incline forward as it extends outward in the radial direction. The inclined portion 40c is formed radially outward of the annular recessed portion 40b and radially inward of the cover portion 4e of the spool 4.

The seal member 50 seals a gap between the spool 4 and the adjustment member 30, and more specifically, the seal member 50 seals a gap between an inner peripheral portion of the front wall portion 4b of the spool 4 and an outer peripheral portion of the cylindrical portion 30c of the adjustment member 30. the seal member 50 is a lip seal having a front end inclined forward, and is attached to an attachment groove 30i formed in an outer peripheral surface of the pressing member 30 g. the seal member 50 is disposed such that the front end contacts the inner peripheral portion of the front wall portion 4b, and a portion of the front surface contacts a rear end portion of the cylindrical portion 30c of the adjustment member 30.

In the spinning reel 100 having the above configuration, moisture entering the inside of the spool 4 from the gap between the cover 4e of the spool 4 and the opposing wall portion 30b of the adjustment member 30 along the cover 4e and the front wall portion 4b enters the annular recess 40b when crossing the annular recess 40b, and the entry of moisture is suppressed. When moisture passes over the annular recessed portion 40b, the annular projecting portion 40a suppresses the intrusion of moisture.

As shown in fig. 3, when the front wall portion 4b of the spool 4 and the opposing wall portion 30b of the adjustment member 30 face in the front-rear direction, the annular recessed portion 40b serves as a flow path for water, and water entering the annular recessed portion 40b moves downward along the inside of the annular recessed portion 40 b. The moisture moving in the annular recess 40b then flows out in a direction away from the center of the take-up drum 4 as shown by the broken line in fig. 3, and therefore the moisture is easily discharged to the outside. Further, by providing the inclined portion 40c, the moisture flowing out of the annular recess 40b is easily guided to the outside.
