In addition, the 2nd penetration long hole 23b is connected and formed so that the annular mounting groove 25 in which the spring member 24 is mounted may partially overlap.

  In order to attach the friction plate 19b to such a mounting cylinder 1c, the friction plate 19b is mounted on the inner periphery while being tilted in the front-rear direction of the mounting cylinder 1c, and the protrusion 19d is mounted in the through long hole 23. When this occurs, the entire friction plate 19b is raised and the projection 19d is locked in the through-hole 23.

  The operation knob 27 is formed in a bottomed cylindrical shape whose rear end is slightly reduced in diameter so that the mounting cylinder portion 1c can be accommodated, and the braking force of the spool 3 can be adjusted by a turning operation. A female screw portion 27 a is formed on the distal end side of the inner peripheral surface of the operation knob 27. An engagement recess 27 b that protrudes toward the pressing member 22 is formed on the bottom surface of the operation knob 27. The engaging recess 27b engages with the connecting portion 22c so as not to rotate but to move in the axial direction. Accordingly, when the operation knob 27 is rotated, the pressing member 22 screwed into the female screw portion 1d is rotated and moved back and forth, the coil spring 21 is expanded and contracted, and the drag force is increased or decreased.

  The screw member 28 includes first and second divided members 28a and 28b having a half-cut cylindrical shape obtained by dividing a hooked cylindrical member into two on the diameter. On the outer peripheral surfaces of the first and second divided members 28a, 28b, large diameter flange portions 31a, 31b that contact the operation knob 27 at the tip portions are formed on the inner peripheral surface of the operation knob 27 at the intermediate portion. Male threaded portions 29a and 29b that can be screwed onto the portion 27a are formed. The flange portions 31a and 31b are formed so as to protrude outward in the radial direction, and the outer diameters of the flange portions 31a and 31b are larger than the outer shapes of the male screw portions 29a and 29b. Accordingly, when the female screw portion 27a formed on the inner periphery of the operation knob 27 is screwed into the male screw portions 29a and 29b formed on the outer periphery of the screw member 28, the operation knob 27 is moved to the flange portion 31a of the screw member 28. , 31b, and can be securely tightened to the screw member 28. At the rear end portions of the inner peripheral surfaces of the first and second divided members 28a, 28b, retaining half-projections 30a, 30b for engaging with the retaining groove 26 are formed projecting radially inward. ing. A pair of positioning protrusions 32a (see FIG. 3) are formed on the split surface of the first split member 28a facing the second split member 28b. A pair of positioning holes (not shown) are formed on the split surface of the second split member 28b facing the first split member 28a. As a result, the two divided members 28a and 28b are reliably positioned, and the divided male screw portions 29a and 29b are aligned so as to be threadably engaged with the female screw portion 27a.

  Next, the operation of the rear drag reel will be described.

  When the yarn is fed from the reel unit 1, the bail arm 4 is tilted to the yarn release side. When the fishing rod is cast, the fishing line is unwound from the spool 3. At the time of winding the yarn, the bail arm 4 is returned to the yarn winding side. When the handle 10 is rotated in the yarn winding direction in this state, this rotational force is transmitted to the pinion gear 12 via the handle shaft 10a and the master gear 11. The rotational force transmitted to the pinion gear 12 rotates the rotor 2 at the front portion of the pinion gear 12. On the other hand, the rotational force transmitted to the pinion gear 12 rotates the screw shaft 15 via an intermediate gear (not shown) that meshes with the pinion gear 12. At this time, the slider 16 engaged with the spiral groove of the screw shaft 15 is guided by the guide shaft and moves in the front-rear direction. When the slider 16 moves, the spool shaft 14 and the spool 3 reciprocate in the front-rear direction together with the slider 16. By such rotation of the rotor 2 and movement of the spool 3 back and forth, the fishing line guided from the bail arm 4 and the line roller 5 is uniformly wound around the outer periphery of the spool 3 in the front-rear direction.

  The rear drag mechanism 9 brakes the spool 3 and can adjust the drag force on the spool 3 by rotating the operation knob 27. When the operation knob 27 at the rear part of the reel body 1 is tightened, the pressing member 22 moves forward, and the coil spring 21 that contacts the pressing member 22 is pressed. Then, the plurality of friction plates 19a, 19b, 19c of the friction engagement portion 19 are pressed against each other, and the bush 18 is pressed toward the reel body 1a by the plurality of friction plates 19a, 19b, 19c. Thus, when the bush 18 is pressed toward the reel body 1a, the spool shaft 14 that cannot rotate with respect to the bush 18 is also difficult to rotate, and the drag force acting on the spool 3 is increased. On the other hand, when the operation knob is loosened, the pressing member 22 moves rearward, and the state where the coil spring 21 is pushed is gradually released. Then, the pressing of the bush 18 by the friction plates 19a, 19b, 19c is released, and the spool shaft 14 that cannot rotate with respect to the bush 18 is easily rotated, and the drag force acting on the spool 3 is weakened.

  In such a rear drag attachment structure for attaching the rear drag mechanism 9 to the reel body 1, the through long hole 23 penetrating from the outer peripheral portion of the mounting cylinder portion 1 c to the inner peripheral portion is provided, so that the female screw portion 1 d is formed. It is possible to attach and remove the core from the center, and therefore, the through long hole 23 and the female screw portion 1d can be formed simultaneously by molding. Therefore, since it is not necessary to post-process the notch groove portion as in the prior art, the mounting cylinder portion 1c can be easily formed.
