JP 2007-54016 A

By the way, in the structure which fastens a cover member to a reel body with a screw, arrangement | positioning of a screw is important. For example, when the screw arrangement is shifted to the side where the screw is arranged, the attachment strength of the lid member is affected.
As a result of intensive studies on the relationship between the mounting strength of the lid member and the screw arrangement, the present inventor has found that the engagement portion (rotation) of the drive gear driven by the rotation of the handle shaft and the pinion gear driven by the drive gear If a plurality of screws are arranged at positions that are evenly distributed in the vertical and longitudinal directions from the meshing part at a position in the vicinity of the part where the reaction force in the direction to try to remove the lid member from the reel body is sometimes generated, It was confirmed that the mounting strength of the lid member was ensured.

However, it is not possible to suppress the reel body and the lid member from bulging and deforming in a direction to remove them due to the reaction force only by arranging the plurality of screws at the dispersed positions.
Further, the position of the screw may not be able to be arranged at a preferred position due to the positional relationship of the internal mechanism.

In this respect, in Patent Document 1, since the reel body and the lid member are fixed by the cylindrical member, it is possible to prevent deformation at the fixed portion. However, since the position at which the reel body and the lid member are fixed by the cylindrical member is largely shifted to the front position rather than the above-mentioned meshing portion, the above-described deformation cannot be suppressed in Patent Document 1.
For this reason, in the cited document 1, there is a possibility that the reel body and the lid member may be deformed, and the positional relationship of the engagement between the drive gear and the pinion gear becomes an inappropriate positional relationship and damages the gear. There is a risk.

  The present invention was made to solve the above problems, and in a fishing spinning reel provided with a lid member that closes the opening side portion of the reel body, the deformation of the reel body and the lid member is prevented, It is an object of the present invention to provide a fishing spinning reel capable of improving durability.

  A spinning reel for fishing according to the present invention that solves such problems includes a reel body including a reel body and a lid member that closes a side opening of the reel body, and a rotor having a fishing line guide portion. A reel for fishing, in which a drive mechanism coupled to a handle shaft for rotationally driving the reel is provided in the reel body, and is a cylindrical shape mounted on the front portion of the reel body inside the rotor. The drive mechanism includes a drive gear driven by rotation of the handle shaft, and a pinion gear driven by the drive gear, and the reel body and the lid member are attached to the reel body. In the state where the lid member is closed, the vicinity of the radially outer peripheral side of the pinion gear at the meshing portion of the drive gear and the pinion gear In the position, the outer peripheral edge portion has a flange portion that is continuous in the circumferential direction, and the front cover is attached to the front portion of the reel body, and the inner peripheral portion of the end portion is the outer periphery portion. It is located so that it may join around a peripheral part, The said outer peripheral part is covered, It is characterized by the above-mentioned.

  According to this spinning reel for fishing, when the side opening of the reel body is closed with a lid member and the front cover is attached to the front portion of the reel body, the inner periphery of the end portion of the front cover becomes the reel body and It is located so as to be joined around the outer peripheral edge of the flange provided on the lid member, and the outer peripheral edge is covered with the end of the front cover. As a result, the reel body and the lid member are held by the end portion of the front cover via the flange portion at a position near the radially outer peripheral side of the pinion gear at the meshing portion of the drive gear and the pinion gear. Further, inside the rotor, the front portion of the reel body is covered with the front cover with the flange portion as a boundary.

  In the present invention, the lid member is provided with an extending portion that extends from the position where the flange portion is provided toward the inside of the front cover, and the extending portion is provided on the reel body. The lid member is in contact with the reel body inside the front cover with the lid member closed.

  According to this spinning reel for fishing, even if a force in the direction of swelling toward the anti-reel body is applied to the lid member, the movement of the lid member is not extended to abut against the reel body inside the front cover. Since the movement is centered on the tip of the protruding portion (fulcrum), it is suitable for the front cover where the rising due to the swelling of the lid member comes into contact with the flange portion located closer to the center of the lid member than the extended portion Will be suppressed.

  Further, the present invention is characterized in that the end portion of the front cover is higher in rigidity than other portions of the front cover.

  According to this fishing spinning reel, the rigidity of the end portion of the front cover holding the flange portion is higher than that of the other portions of the front cover, so that lifting due to the swelling of the lid member can be suitably suppressed. Become.

  Further, according to the present invention, the flange portion of the reel body and the flange portion of the lid member are both arc-shaped, and the lid member is closed when the lid member is closed on the reel body. The outer peripheral edge portion is circular when viewed from the axial direction of the pinion gear.

  According to this fishing spinning reel, the flange portion of the reel body and the flange portion of the lid member are both arcuate, and the outer peripheral edge of the flange portion in the combined state is viewed from the axial direction of the pinion gear. Since it is circular, the joining accuracy with the end portion of the front cover can be improved.

  Further, the present invention is characterized in that the front cover is attached to the front portion of the reel body by screwing.

  According to the fishing spinning reel, the front cover can be easily fixed to the front portion of the reel body by screwing.

  Further, in the present invention, the lid member is fastened to the reel body by a screw, and the reel body is in an unfastened state by the screw at a portion facing the reel body and the lid member. And a restricting means for restricting the lid member from moving toward the front cover side and restricting the lid member from rotating about the handle shaft relative to the reel body. It is characterized by that.

  According to this fishing spinning reel, when the side opening of the reel body is closed with the lid member, and the front cover is attached and the flange portion is held, the lid member is placed on the side opposite to the front cover by the restricting means. And the rotation of the lid member around the handle shaft with respect to the reel body is restricted.

  According to the present invention, the reel body and the lid member are held by the end portion of the front cover via the flange portion at a position near the radially outer peripheral side of the pinion gear at the meshing portion of the drive gear and the pinion gear. Therefore, in the vicinity of the meshing portion of the drive gear and the pinion gear (the portion where the reaction force is generated in the direction of removing the lid member from the reel body during rotation), this can be suitably suppressed. It is possible to suitably suppress the lid member from being deformed (for example, bulging and deforming) in a direction perpendicular to the mating surface (handle axis direction). Thereby, durability can be improved.

When the flange portion is provided closer to the center portion than the front end portion of the lid member, the side close to the center portion of the lid member is held by the front cover, so that the reel body and the lid member are perpendicular to the mating surface. It is possible to more suitably suppress deformation (for example, bulging deformation) in the direction (the handle shaft direction).
Since deformation can be suitably suppressed in this manner, the load on the screw or the like used for fastening the lid member is reduced, and durability is improved.
Further, by reducing the load, it is possible to reduce the size of the screw and the size of the boss portion, and the overall strength of the portion related to the fastening of the screw can be set. Thereby, cost reduction can be aimed at.
Furthermore, since the reel body and the lid member can be held by the front cover, the degree of freedom in the screw arrangement position is increased, and the degree of freedom in designing the drive mechanism and the like is also increased.
In addition, even if the screw used for fastening is loosened, the holding of the reel body and the lid member by the front cover is maintained, so that the lid member does not fall off from the reel body.

  In addition, since the front part of the reel unit is covered with the front cover, the outer shape of the front part of the reel unit is simple and clean. As a result, dirt and the like are difficult to collect and cleaning is also easy. .

  Furthermore, in the configuration having the extending portion, the flange portion is positioned closer to the center portion side of the lid member than the extending portion, and the lifting due to the swelling of the lid member is suitably suppressed by the holding by the front cover. Compared to the case where there is no extension part, it is possible to suitably suppress the reel body and the lid member from being deformed (for example, bulging and deforming) in a direction perpendicular to the mating surface (the handle shaft direction). Thereby, durability can be improved.

  In addition, in the configuration in which the rigidity of the end portion of the front cover that holds the flange portion is higher than that of the other portions of the front cover, the lifting due to the swelling of the lid member is suitably suppressed. It is possible to more suitably suppress deformation (for example, bulging deformation) of the member in a direction (handle axis direction) perpendicular to the mating surface. Thereby, durability can be further improved.

  Furthermore, in the configuration in which the outer peripheral edge of the flange portion is circular when viewed from the axial direction of the pinion gear in the combined state, the joining accuracy with the end portion of the front cover can be improved, so that assembly is easy to perform. It is possible to improve productivity. In addition, since productivity is improved, cost can be reduced.

  In addition, in the configuration in which the front cover is attached to the front part of the reel body by screwing, the front cover can be easily attached and fixed by screwing, so there is no need for additional fixing means such as screws and the number of parts. It is possible to improve productivity and reduce costs by reducing the cost. In addition, there is an advantage that the structure becomes simple.

  Further, in the configuration in which the restricting means is provided, when the flange portion is held by the front cover, the restricting means restricts the lid member from moving toward the front cover side relative to the reel body, and the reel body Since the lid member is restricted from rotating around the handle shaft, the lid member will not come off the reel body even if it is not fastened with screws when the front cover is attached. Improves. As a result, productivity is improved and costs can be reduced.

As shown by a thick arrow in FIG. 8, it is possible to suitably suppress the reel body 10 and the lid member 20 from being deformed (for example, bulging deformation) in a direction perpendicular to the mating surface (direction of the handle shaft 4). . Thereby, durability can be improved.

Further, since the flange portions 12 and 22 are provided closer to the center portion than the front end portion of the lid member 20, the front cover is interposed via the flange portions 12 and 22 on the side closer to the center portion than the front end portion of the lid member 20. 30 and the reel body 10 and the lid member 20 can be more preferably prevented from being deformed (for example, bulging deformation) in a direction perpendicular to the mating surface (direction of the handle shaft 4).
Since deformation can be suitably suppressed in this manner, the load on the screw 20a used for fastening the lid member 20 is reduced, and durability is improved.
Further, by reducing the load, it is possible to reduce the size of the screw 20a and the size of the boss (screw hole 13b, etc.), and to set the overall strength of the portion related to fastening of the screw 20a to be small. It becomes possible. Thereby, cost reduction can be aimed at.
Furthermore, since the reel body 10 and the lid member 20 can be held by the front cover 30, the degree of freedom in the arrangement position of the screw 20a is increased, and the degree of freedom in designing the drive mechanism and the like is also increased.
In addition, even if the screw 20a used for fastening is loosened, the holding of the reel body 10 and the lid member 20 by the front cover 30 is maintained, so that the lid member 20 may drop from the reel body 10. There is no.

  In addition, since the front part of the reel unit 1 is covered with the front cover 30, the outer shape of the front part of the reel unit 1 is simple and clean. As a result, dirt and the like are difficult to collect, and cleaning is also possible. It becomes easy to do. Further, as shown in FIG. 8, since the concave space S1 formed in front of the flange portions 12 and 22 is covered with the front cover 30, dirt and dust do not accumulate in the concave space S1.

Further, since the cover member 20 is provided with an extending portion 23a extending from the position where the flange portion 22 is provided toward the inside of the front cover 30, as shown in FIG. Even if a force in the direction of swelling toward the anti-reel body 10 (a force in the direction of the white arrow) is applied to the lid member 20 from the state where the 20 is in the normal position, as shown in FIG. 9B. The movement of the lid member 20 is a movement centered on the tip P1 of the extending portion 23a that is in contact with the reel body 10 inside the front cover 30 (fulcrum), so that the lid member is more than the extending portion 23a. The flange portion 22 located on the center portion side of the 20 abuts against the end portion 32 of the front cover 30 and the inner peripheral surface of the front cover 30, and the lifting due to the swelling of the lid member 20 is suitably suppressed.
Therefore, it is possible to more suitably suppress the reel body 10 and the lid member 20 from being deformed (for example, bulging deformation) in a direction perpendicular to the mating surface (the direction of the handle shaft 4). Thereby, durability can be further improved.

On the other hand, as shown in FIG. 9C, when the extending portion 23a is not provided, the flange portion 22 moves to the front (center) as a center (fulcrum) at the lower end of the flange portion 22. The reel body 10 and the lid member 20 may be deformed (for example, bulging deformation) in a direction perpendicular to the mating surface (in the direction of the handle shaft 4). There is a possibility that it cannot be sufficiently suppressed.
On the other hand, since the lid member 20 of the present embodiment has the extending portion 23a, the flange portion 22 contacts the end portion 32 of the front cover 30 and the inner peripheral surface of the front cover 30 as described above. In contact therewith, the lifting due to the swelling of the lid member 20 is suitably suppressed, and the deformation can be suitably suppressed.

  Further, since the end portion 32 of the front cover 30 is higher in rigidity than the other portions of the front cover 30, the lifting due to the swelling of the lid member 20 is suitably suppressed, and the reel body 10 and the lid member 20 are mated surfaces. It is possible to more suitably suppress deformation (for example, bulging deformation) in a direction perpendicular to the direction (the direction of the handle shaft 4). Thereby, durability can be further improved.

  The flange portion 12 of the reel body 10 and the flange portion 22 of the lid member 20 are both arc-shaped, and the outer peripheral edge portions of the flange portions 12 and 22 in a state where the lid member 20 is closed by the reel body 10. Since 12a and 22a become circular shape seeing from the axial direction of the pinion gear 8a, the joining precision with the edge part 32 of the front cover 30 can be improved, it becomes easy to assemble | attach and it can aim at the improvement of productivity. . In addition, since productivity is improved, cost can be reduced.

  In addition, since the front cover 30 is simply mounted and fixed to the front portion of the reel body 1 by screwing, no additional fixing means such as screws is required, and productivity can be improved and cost can be reduced by reducing the number of parts. It becomes possible. In addition, there is an advantage that the structure becomes simple.

  Further, when the flange portions 12 and 22 are held by the front cover 30, the lid member 20 moves to the side opposite to the front cover 30 with respect to the reel body 10 due to the locking of the protrusion 14 and the concave portion 24 that function as the restricting means. In addition, since the lid member 20 is restricted from rotating around the handle shaft 4 with respect to the reel body 10, all the fastening by the screw 20 a is temporarily performed when the front cover 30 is attached. Even if it is not, the lid member 20 is not detached from the reel body 10, and workability at the time of assembly is improved. As a result, productivity is improved and costs can be reduced.

(Second Embodiment)
FIG. 10 shows a fishing spinning reel of the second embodiment. The present embodiment is different from the first embodiment in that the end portion (rear end portion) 32 of the front cover 30 extends toward the flange portions 12 and 22 and is formed thick in the radial direction.

By forming the thick portion in this way, the end portion 32 has higher rigidity than the other portions of the front cover 30. As a result, the lifting due to the swelling of the lid member 20 is suitably suppressed, and the reel body 10 and the lid member 20 are deformed (for example, bulged and deformed) in a direction perpendicular to the mating surface (the direction of the handle shaft 4). It can suppress more suitably.
Thereby, durability can be further improved.
The end portion 32 may be formed thick in the front-rear direction of the front cover 30 in addition to being formed thick in the radial direction. Further, the end portion 32 may be formed by changing the material.
