  As a first method, a method of inserting the jig J from the opening 14g on the handle 2 mounting side is shown in FIG. The jig J has two first tip portions J1 and a second tip portion J2, and is a rod-like shape that can be folded and expanded in a direction in which the first tip portion J1 and the second tip portion J2 come in contact with and separate from each other. It is a member. Here, first, the handle shaft 30 and the inner ring 55b of the one-way clutch 55 are removed, and the bearing 35a is removed from the bearing mounting portion 14c. Next, as shown in FIG. 7, the jig J is folded so that the two first tip J1 and the second tip J2 of the jig J approach each other so as not to contact the opening 14g on the handle 2 mounting side. Then, the inner peripheral portion of the flange portion 14e is inserted through the opening 14g on the handle 2 mounting side. Next, the two first tip portions J1 and the second tip portion J2 of the jig J are expanded and returned to the original state, and the first tip portion J1 and the second tip portion J2 of the jig J are moved from the inner peripheral side to 2 It inserts in the concave part 14f for jig insertion of the location. Then, the two first tip portions J1 and the second tip portion J2 of the jig J are locked to the outer peripheral portion of the tip of the outer ring 55a of the one-way clutch 55, and the one-way clutch 55 is opposite to the handle 2 mounting side (left side in FIG. 7). The one-way clutch 55 is removed by pushing it out.

  As a second method, a method of inserting the jig J from the opening 14h on the side opposite to the handle 2 mounting side is shown in FIG. Here, first, the handle shaft 30 and the inner ring 55b of the one-way clutch 55 are removed. Next, as shown in FIG. 8, the two first tip portions J1 and J1 of the jig J are arranged so that the jig J does not come into contact with the inner peripheral portion of the one-way clutch 55 from the opening 14h opposite to the handle 2 mounting side. 2 The inner periphery of the one-way clutch 55 is inserted through the opening 14h on the opposite side of the handle 2 mounting side in a state where the front end J2 is folded so as to approach. Next, the two first tip portions J1 and the second tip portion J2 of the jig J are expanded and returned to the original state, and the first tip portion J1 and the second tip portion J2 of the jig J are moved from the inner peripheral side to 2 It inserts in the concave part 14f for jig insertion of the location. Then, the two first tip portions J1 and the second tip portion J2 of the jig J are locked to the outer peripheral portion of the tip of the outer ring 55a of the one-way clutch 55, and the one-way clutch 55 is opposite to the handle 2 mounting side (left side in FIG. 7). The one-way clutch 55 is removed by pulling it out.

  The claw-type one-way clutch 60 rotates the handle shaft 30 only in the yarn winding direction. As shown in FIGS. 2 and 3, the claw-type one-way clutch 60 includes a ratchet wheel 61 that is rotatably attached to the handle shaft 30 and a ratchet claw 62 that can mesh with the ratchet wheel 61. . The ratchet pawl 62 is biased toward the ratchet wheel 61 side.

  The clutch operation mechanism 22 has a clutch operation lever 40 for operating the clutch mechanism 21 as a clutch-on operation and a clutch-off operation. Move to.

  Next, the operation of the round reel during jigging will be described.

  When the fishing line is fed out, the clutch operating lever 40 is operated to bring the clutch mechanism 21 into the clutch-off state. As a result, the spool 15 is in a freely rotating state, the spool 15 rotates in the line feeding direction due to its own weight, and the fishing line is fed out from the spool 15.

  When the mechanism reaches the seabed, the handle 2 is rotated in the yarn winding direction to start vertical jigging. When the handle 2 is rotated in the yarn winding direction, the clutch mechanism 21 is turned on by the action of a clutch return mechanism (not shown). The rotation of the handle 2 is transmitted from the drive gear 31 to the spool 15 via the pinion gear 32, and the spool 15 rotates in the yarn winding direction. At this time, the one-way clutch 55 and the claw-type one-way clutch 60 are allowed to rotate because the rotation is in the yarn winding direction.

  When performing vertical jigging, for example, the rear end (not shown) of the fishing rod R is sandwiched on the left side, the thumb of the left hand is placed on the thumb rest 17 fixed to the rear of the reel body 1, and the fishing rod R is grasped with the remaining fingers. While holding the reel and the fishing rod R, the pumping operation of turning the handle shaft 30 at a high speed by pinching the handle handle 7 of the handle 2 with the right hand while sucking the fishing rod R with the left hand is repeated. In this case, since the rotation speed of the handle 2 is further increased, it is difficult to feel the amplitude, and the rotation feeling is further improved.

  When the handle 2 is rotated in the yarn winding direction, the rotation of the handle 2 is transmitted as it is from the handle shaft 30 to the drive gear 31 via the one-way clutch 55 and the drag mechanism 57. At this time, since the clutch mechanism 21 is in the clutch-on state, the rotation of the drive gear 31 is transmitted from the pinion gear 32 to the spool 15 and the fishing line is wound up.

  Next, when the fishing line is fed out by pulling a fish or the like, the rotation of the spool 15 is transmitted to the drive gear 31 and is transmitted to the handle shaft 30 and the one-way clutch 55 via the drag mechanism 57. In the one-way clutch 55, the reverse rotation of the handle shaft 30 is prohibited. If the fish pull is weak, the spool 15 does not rotate and the fishing line is not pulled out. When the fish pull becomes strong and the rotational force of the spool 15 increases, the transmitted rotational force exceeds the set rotational resistance force of the drag mechanism 57. Then, since slip occurs in the drag mechanism 57, the spool 15 side including the drive gear 31 starts to rotate. At this time, a constant resistance force, that is, a drag force is always applied to the spool 15 from the drag mechanism 57. At this time, a strong reaction force acts on the pinion gear 32 in the radial direction. However, since the pinion gear 32 is supported at both ends by the bearing 27a and the bearing 27b, the pinion gear 32 does not escape in the radial direction, and the drive gear The meshing with 31 is maintained.

  In such a one-way clutch 55 of a dual-bearing reel, a part of the flange portion 14e including a contact surface that contacts at least the outer peripheral portion of the one-way clutch 55 is cut out on the inner peripheral side and inserted from the inner peripheral side. A jig insertion recess 14f is provided in which the jig J is locked to the outer periphery of the tip of the one-way clutch 55 and the one-way clutch 55 can be removed. Here, since the jig J inserted from the inner peripheral side is locked to the outer peripheral portion of the tip of the one-way clutch 55 and the one-way clutch 55 can be removed, a jig insertion recess 14f is provided. The one-way clutch 55 can be removed without destroying the first protrusion 14a. Therefore, the one-way clutch 55 can be easily detached while maintaining the shape of the reel body 1.
