Japanese Unexamined Patent Publication No. 2012-100624

The knob member of Patent Document 1 is provided so as to fit within a bulging portion that bulges outward in the axial direction of the second side cover when viewed from the axial direction. That is, when viewed from the axial direction, the outer circumference of the knob member does not protrude from the bulging portion (see FIG. 2). In such a configuration, the bulging portion makes it difficult to put a finger on the knob member, the rotation operation of the knob member is difficult, and the braking force acting on the spool cannot be easily adjusted.

An object of the present invention is to improve the operability of the casting control mechanism in both bearing reels.

The double-bearing reel according to one aspect of the present invention has a spool that rotates according to the rotation of the spool shaft and the handle, and can feed the fishing line forward, and includes a reel body, a cover member, and a casting control mechanism. , Is equipped. The reel main body has a first side plate, a second side plate provided at a distance between the first side plate and the spool shaft in the axial direction, and a connecting portion for connecting the first side plate and the second side plate. The cover member is arranged so as to cover the first side plate side of the reel body, and has a cover portion located axially outside the first side plate, a bulging portion bulging outward from the cover portion in the axial direction, and a bulging portion. It has a first boss portion, which is formed so as to project outward in the axial direction from the portion and through which the spool shaft is inserted. The casting control mechanism is mounted on the first boss portion so as to be movable in the axial direction, and has an operating member having a part of the outer circumference protruding from the bulging portion when viewed from the axial direction. Adjust the braking force acting on the spool by moving.

In this double bearing reel, when viewed from the axial direction, a part of the outer periphery of the operating member protrudes from the bulging portion of the cover member, so that the operating member can be easily operated. As a result, the braking force acting on the spool can be easily adjusted, so that the operability of the casting control mechanism is improved.

Preferably, the cover member has a stepped portion extending axially outward from the cover portion and connecting the cover portion and the bulging portion. In this case, a part of the outer circumference of the operating member protrudes from the step portion when viewed from the axial direction.

Preferably, the step portion has an inclined portion in which the portion close to the operating member is inclined in the direction toward the axial center of the spool shaft as the cover portion approaches the bulging portion. In this case, a part of the outer circumference of the operating member can be easily projected from the bulging portion without increasing the outer diameter of the operating member.

Preferably, the inclined portion is formed so as to extend in an arc shape when viewed from the axial direction. In this case, since the inclined portion functions as a regulating portion that regulates the rotation operation range of the operating member, it is possible to prevent the operating member from being overtightened or loosened.

Preferably, the operating member is a bottomed cylindrical rotating member whose inner peripheral portion is rotatably mounted on the outer peripheral portion of the first boss portion, and has a smaller diameter than the outer diameter of the small diameter portion and the small diameter portion. Moreover, it has a large-diameter portion that is formed on the outer side in the axial direction from the small-diameter portion and a part of the outer circumference protrudes from the bulging portion when viewed from the axial direction. In this case, it is possible to prevent the bulging portion and the large diameter portion from coming too close to each other in the axial direction, so that the operating member can be easily operated.

Preferably, the cover member further has a second boss portion that projects axially outward from the bulge portion in front of the first boss portion, and both bearing reels are driven to axially penetrate the second boss portion. It also has a shaft. In this case, for example, even when the handle is arranged on the same first cover side as the operation member, the operation member can be easily operated without being disturbed by the handle.

According to the present invention, the operability of the casting control mechanism can be improved in both bearing reels.

FIG. 1 is a sectional view taken along line III-III. A perspective view around the first side cover. Bottom view around the operating member.

The double-bearing reel 100 in which one embodiment of the present invention is adopted is a double-bearing reel capable of feeding fishing line forward, and as shown in FIGS. 1, 2 and 3, the reel body 1 and the spool shaft 2 are used. , A spool 3, a handle 4, a rotation transmission mechanism 5, and a casting control mechanism 6. In the following description, the term "front and back" refers to the direction in which the fishing line is unwound when fishing is performed, and the opposite direction is referred to as "rear". For example, in FIG. 1, the right side is the front and the left side is the back. Further, the axial direction means a direction in which the spool shaft 2 extends.

The reel main body 1 has a plurality of connecting portions 7c that connect the first side plate 7a, the second side plate 7b arranged at intervals in the axial direction from the first side plate 7a, and the first side plate 7a and the second side plate 7b. And a rod mounting portion 7d on which a fishing rod is mounted.

The first side plate 7a is a substantially disk-shaped member having an opening 7e for taking out the spool 3. The outside of the first side plate 7a is covered with a first side cover 8 (an example of a cover member).

The first side cover 8 has a cover portion 10, a bulging portion 11, and a stepped portion 12. Further, the first side cover 8 further has a first boss portion 13 and a second boss portion 14 (see FIG. 3). The cover portion 10 is arranged axially outside the first side plate 7a and covers a part of the first side plate 7a.

The bulging portion 11 is formed so as to bulge outward in the axial direction from the cover portion 10. Further, as shown in FIGS. 1 and 4, the bulging portion 11 is formed so as to bulge forward from the cover portion 10.

The step portion 12 extends outward in the axial direction from the cover portion 10 and connects the cover portion 10 and the bulging portion 11. The step portion 12 has an inclined portion 12a at a portion close to the outer edge of the first boss portion 13. The details of the inclined portion 12a will be described later.

The first boss portion 13 is formed so as to project outward in the axial direction from the bulging portion 11 at a position close to the step portion 12. The first boss portion 13 has a male screw portion 13a on the outer peripheral surface.

The second boss portion 14 is formed so as to project outward in the axial direction from the bulging portion 11 at a position in front of the first boss portion 13. The second boss portion 14 has an annular protrusion 14a extending radially outward on the outer peripheral surface.

The second side plate 7b is integrally formed with the second side cover 9 that covers the second side plate 7b of the reel main body 1. The second side plate 7b and the second side cover 9 may be formed separately.

The spool shaft 2 is rotatably supported by the reel body 1 via bearings 15a and 15b arranged on the reel body 1. The spool shaft 2 extends further outward in the axial direction from the first side plate 7a and inserts the first boss portion 13 of the first side cover 8.

The spool 3 is fixed to the spool shaft 2 penetrating the center of the spool 3, and rotates together with the spool shaft 2 between the first side plate 7a and the second side plate 7b.

The handle 4 is provided on the first side plate 7a side of the reel main body 1. In response to the rotation operation of the handle 4, the spool 3 rotates together with the spool shaft 2 via the rotation transmission mechanism 5.

As shown in FIG. 3, the rotation transmission mechanism 5 includes a drive shaft 20, a drive gear 21, a cylindrical pinion gear 22, and a drag mechanism 23. The drive shaft 20 penetrates the second boss portion 14 of the first side cover 8 in the axial direction and is non-rotatably connected to the handle 4. The drive shaft 20 is rotatably supported with respect to the reel main body 1 by bearings 24a and 24b arranged on the reel main body 1 and the second boss portion 14 of the first side cover 8. The drive shaft 20 is prohibited from rotating in the fishing line feeding direction by the one-way clutch 25 arranged on the second boss portion 14 of the first side cover 8.

The drive gear 21 is mounted on the drive shaft 20. Both ends of the pinion gear 22 are supported by bearings 26a and 26b arranged on the reel main body 1 and the first side cover 8. The pinion gear 22 is mounted around the spool shaft 2 and meshes with the drive gear 21. The rotation of the drive shaft 20 is transmitted to the pinion gear 22 via the drag mechanism 23 and the drive gear 21, and the rotation of the pinion gear 22 causes the spool 3 to rotate together with the spool shaft 2.

The drag mechanism 23 is for braking the rotation of the spool 3 in the fishing line feeding direction. Since the drag mechanism 23 has the same configuration as the conventional one, detailed description thereof will be omitted. In this embodiment, the cylindrical moving member 23a constituting a part of the drag mechanism 23 is arranged so as to cover a part of the outer peripheral portion of the second boss portion 14 of the first side cover 8. More specifically, the moving member 23a is arranged so as to cover the radial outside of the annular protrusion 14a of the second boss portion 14. As a result, water is suppressed from entering the inside of the first side cover 8 through the gap between the moving member 23a and the second boss portion 14 of the first side cover 8.

The casting control mechanism 6 is for adjusting the braking force acting on the spool 3 by pressing the spool shaft 2. As shown in FIG. 3, the casting control mechanism 6 includes a first friction plate 30, a second friction plate 31, and a bottomed cylindrical operating member 32.

The first friction plate 30 is arranged at the bottom of the operating member 32. The second friction plate 31 is arranged on the second side cover 9. The first friction plate 30 and the second friction plate 31 are arranged so as to sandwich both ends of the spool shaft 2 and press the spool shaft 2 in the axial direction.

The operation member 32 is rotatably attached to the first boss portion 13 of the first side cover 8. The operating member 32 has a female screw portion 32a, an annular small diameter portion 32b, and an annular large diameter portion 32c located axially outside the small diameter portion 32b. The female screw portion 32a is formed on the inner peripheral surface of the operating member 32. By screwing the female threaded portion 32a into the male threaded portion 13a of the first boss portion 13 of the first side cover 8, the operating member 32 is attached to the first boss portion 13 so as to be movable in the axial direction.

The small diameter portion 32b is provided at a position close to the step portion 12 of the first side cover 8. The small diameter portion 32b is provided so that the bulging portion 11 of the first side cover 8 and the large diameter portion 32c are not too close to each other in the axial direction.

The large-diameter portion 32c is a portion that is rotated by pressing a thumb against the outer peripheral surface or picking it up with two fingers. The outer peripheral surface of the large diameter portion 32c is subjected to anti-slip treatment by, for example, knurling. The large diameter portion 32c has an outer diameter larger than the outer diameter of the small diameter portion 32b, and the axial length is formed to be longer than the small diameter portion 32b. As shown in FIGS. 1 and 5, the large diameter portion 32c is configured such that a part of the outer periphery thereof protrudes from the bulging portion 11 of the first side cover 8 when viewed from the axial direction. Note that FIG. 5 is a bottom view of the periphery of the operating member 23.

The braking force acting on the spool 3 is adjusted by rotating the large diameter portion 32c of the operating member 32. Specifically, when the large diameter portion 32c of the operating member 32 is rotated, the operating member 32 moves in the axial direction. Along with the axial movement of the operating member 32, the first friction plate 30 arranged at the bottom of the operating member 32 moves in the axial direction. As a result, the pressing force in the axial direction acting on the spool shaft 2 changes, and the braking force acting on the spool 3 is adjusted.

Here, as shown in FIG. 5, the stepped portion 12 connecting the cover portion 10 and the bulging portion 11 of the first side cover 8 becomes an operation member 32 as the cover portion 10 approaches the bulging portion 11. The adjacent portion has an inclined portion 12a that is inclined in a direction approaching the axis O of the spool shaft 2. By providing the inclined portion 12a, a part of the large diameter portion 32c can be projected from the bulging portion 11 of the first side cover 8 in the axial direction without increasing the outer diameter of the large diameter portion 32c. can. By projecting a part of the large diameter portion 32c from the bulging portion 11 of the first side cover 8, the operation member 32 can be easily rotated, and the braking force acting on the spool 3 can be easily adjusted. Can be done.

Further, as shown in FIGS. 1 and 4, in the present embodiment, when viewed from the axial direction, the inclined portion 12a extends in an arc shape with a radius of curvature smaller than the radius of curvature of the large diameter portion 32c of the operating member 32. It is formed. As a result, the inclined portion 12a functions as a regulating portion that regulates the rotation operation range of the operating member 32. Specifically, when the thumb is pressed against the outer peripheral surface of the large diameter portion 32c of the operating member 32 to rotate the operating member 32, the belly of the thumb applied to the large diameter portion 32c hits the surface of the inclined portion 12a. .. That is, the rotation operation range of the operation member 32 is restricted by rotating the operation member 32 while moving the thumb along the inclined portion 12a. Therefore, it is possible to intuitively recognize how much the operating member 32 has been rotated. Further, by restricting the rotation operation range of the operation member 32, it is possible to prevent the operation member 32 from being overtightened or loosened. This makes it possible to easily finely adjust the braking force acting on the spool 3.
