【Example】

 As shown in FIG. 1, the left and right side bodies are formed by the side frame B and the side case A, respectively, and the thread guides are moved to the left and right by rotating the screw shaft 1 at the front part between the left and right side frames B. A level wind mechanism having a structure for reciprocating 2 is arranged, a spool 3 is arranged at the center and a clutch operation tool 4 is arranged at the rear, and a handle 5, a drag operation tool 6 and a cast controller 7 are provided on the right side case A. Each is equipped with a dual-bearing reel for bait casting.

As shown in FIG. 1, the handle shaft 8 is supported between the right side case A and the right side frame B, and the handle shaft 8 is provided with the handle 5 and the drag operating tool 6, respectively. A drag mechanism D and an output gear 9 are provided at the inner end of the shaft 8, and a unidirectional bearing 11 acting on the handle shaft 8 is provided at an insertion boss portion 10 of the right side case A through which the handle shaft 8 is inserted. The reverse rotation of the handle 5 is prevented, and the driving force from the handle 5 is transmitted to the input gear 12 of the screw shaft 1 via the output gear 9 and the intermediate gear.

At the inner end of the handle shaft 8, there is provided a bearing 14 that is retained by a retaining ring 13, and a retainer 15 that prevents the bearing 14 from falling off causes the handle shaft 8 to move to the right side frame B. On the handle-side surface of the drag operation tool 6, there is provided a disk 16 that rotates together with the drag operation tool 6, and an engaging pin 17 that engages and disengages with the uneven surface 16A of the disk 16 is provided. Be prepared for the handle 5 so that the operation amount of the drag operation tool 6 can be grasped by clicking sound.

Further, a clutch mechanism C is constituted by an engagement / disengagement structure of a clutch sleeve 19 loosely fitted on the spool shaft 18 so as to be freely slidable with a pin 18A formed on the spool shaft 18, and an input gear 19A of the clutch sleeve 19 and an input gear 19A. The engagement with the output gear 20 of the drag mechanism D constitutes a transmission system that transmits the rotational operation force from the handle 5 to the spool 3 via each of the drag mechanism D and the clutch mechanism C.

Next, a mounting structure of the one-way bearing 11 will be described. As shown in FIG. 1, the one-way bearing 11 is non-rotatable relative to the outer ring body 21 which is fitted into the insertion boss portion 10 of the right side case A and the handle shaft 8 and is slidable in the axial direction. The inner ring body 22 and the roller type rolling element 23 located between the inner and outer ring bodies 21 and 22 are formed. The outer ring body 21 is formed into a circular cross section and is fitted to the insertion boss portion 10. It is embedded. A vertical wall is formed around the outer end portion of the insertion boss portion 10, and at the same time, the vertical wall and one end surface of the outer ring body 21 are formed with engaging portions 24 that engage with each other at a plurality of circumferential positions. A detent structure for the outer race 21 is formed. As shown in FIGS. 2 and 3, the engaging portion 24 of the outer race 21 is formed in the tapered engaging concave portion 24A, so that the engaging engaging portion 24B is easily engaged with the mating engaging convex portion 24B, and By tightening the outer ring body 21 in the mating direction, the engaged state becomes firm and rattling can be suppressed. Reference numeral 25 in the drawing denotes a retaining ring for the outer ring body 21, and even if the fitting tolerance of the outer ring body 21 is set to be loose, a leaf spring or the like is interposed between the retaining ring 25 and the side surface of the outer ring body 21. As a result, rattling can be further suppressed by cooperation with the shape of the tapered engagement portion. When the drag operation tool 6 is tightened, the nut 26 screwed into the handle shaft 8 is advanced and acts on the inner ring body 22 via the leaf spring 27 to move the inner ring body 22 in the axial center direction. It is configured to change the operating force for the drag mechanism D. As described above, by providing the one-way bearing 11, the handle 5 can be rotated in the yarn winding direction, and rotation in the opposite direction is restricted.

[Other Embodiment] A state in which the one-way bearing 11 is used as a stopper of a spinning reel will be described. As shown in FIG. 4, a cylindrical shaft 28 having a rotary frame 34 attached thereto so as to be integrally rotatable is externally fitted onto a spool shaft 29 in an idle state, and a space between the rotary frame 34 and the front wall surface of the reel body 30 is fixed. The direction bearing 11 is positioned and externally fitted to the cylinder shaft 28. The one-way bearing 11 is composed of an outer ring body 21, an inner ring body 22, and a rolling element 23, and an engaging portion 24 that engages with the outer ring body 21 and the front wall surface of the reel unit 30 is formed. It adopts a configuration to prevent the rotation of the. An annular recessed groove is formed on the outer peripheral surface of the outer ring body 21, and an operation piece 31 is provided which engages with the annular recessed groove. The operation piece 31 penetrates the reel body 30 in the front-rear direction and projects rearward. It is formed integrally with the operation tool 32. On the other hand, an urging spring 33 for urging the one-way bearing 11 in the engaging direction is provided between the vertical wall of the rotary frame 34 and the inner ring 22, and the switching operation tool is resisted against the urging force of the urging spring 33. The operation piece 31 can be moved forward by the action of the cam surface that swings and rotates 32 around the support shaft, and the engagement state of the outer ring body 21 can be released. With the above configuration, when the outer ring body 21 is released from the engaged state, the cylinder shaft 28 rotates in any direction, and when the outer ring body 21 is set to the engaged state, the cylinder shaft 28 moves in the line winding direction. It rotates, but not in the opposite direction. The cross-sectional shape of the outer peripheral surface of the outer race 21 does not necessarily have to be circular. Further, in the case of the form that slides in the axial direction as described above, by forming the engaging portion 24 on the side end surface, a spline is formed as in the case of forming on the outer peripheral surface. Compared with the case where it is necessary to do so, the engaging close contact length of the engaging portion 24 can be shortened, which is advantageous in terms of the engaging accuracy in manufacturing etc., and there is less rattling at the time of assembly. What forms the engaging portion 24 at one end of the outer race 21 is not limited to unidirectional bearings, but may be general bearings, which are collectively referred to as bearing members. The one-way bearing 11 may have any structure as long as it includes the outer race 21 and the rolling elements 23, and the inner race 22 may be omitted. What is externally fitted to the outer ring body 21 may be a rotating body such as a gear and may not be a fixed member such as the reel main body 30. These are collectively referred to as an outer fitting member. The position for mounting the bearing member 11 is set in the vicinity of the right side frame B by replacing the drag mechanism D and the engaging portion 24 is provided between the right side frame B and the outer ring body 21 of the bearing member 11. You may form. The engagement concave portion 24A and the engagement convex portion 24B shown in FIG. 3 may be formed by switching the target. The engaging portions 24 may be formed on both ends of the outer race 21.
