In order to achieve the above object, the present invention axially freely fits a shaft cylinder that rotates integrally with a support shaft rotatably supported by a reel side plate by the winding rotation of a handle, to the shaft cylinder. A drive gear that meshes with a pinion that rotates a spool is fitted, and the friction transmission force can be adjusted by pressing the drive gear and the shaft cylinder with a braking member by axial movement of a projection formed on the shaft cylinder. The drag adjusting knob, which is coupled to the inside of the elastic member so as to prevent the elastic member from slipping off, is screwed into the outer end of the support shaft so as to be able to move forward and backward, and the outer end of the shaft cylinder is pressed by the elastic member. An engaging projection of an annular spring locked in the dish-shaped holder fixed to the outer end of the shaft cylinder is engaged with the uneven portion formed on the inner peripheral surface of the outer portion of the drag adjusting knob. . The present invention can be applied to an ordinary drag device of a dual bearing type reel in which a handle is directly attached to a shaft cylinder, and to a dual bearing type reel having a manual speed change mechanism using a planetary gear mechanism. In this case, the handle is provided on the outside of the shaft cylinder on the handle rotating cylinder that rotates in the fishing line winding direction with the one clutch, and the planetary gear and the sun gear that meshes with the planetary gear between the handle rotating cylinder and the shaft cylinder. A planetary gear mechanism including an internal gear and an internal gear is provided, and by controlling the rotation of the sun gear, the spool can be manually wound at high speed or low speed.

[Action]

When the drag adjusting knob is rotated to move in and out on the support shaft, the shaft cylinder is pressed by the elastic member, and the degree of frictional coupling between the shaft cylinder and the drive gear by the braking member is adjusted to strong or weak, and the spool is moved. It is for braking the drag, the annular spring adds a moderation to the rotation of the drag adjusting knob, the elastic member is fitted inside the drag adjusting knob to prevent it from slipping off, and the annular spring is attached to the disc-shaped holding body. It is locked and united respectively.

An embodiment of the present invention will be described with reference to the drawings. A handle 3 is integrally fixed to a support shaft 2 which is rotatably supported outward from a frame 1'of one reel side plate 1 of a dual bearing type reel. The shaft cylinder 4 is movably fitted in the axial direction, and a drive gear 8 meshing with a pinion 7 of a spool shaft 6 provided with a spool 5 is rotatably fitted to the shaft cylinder 4 as known in the art. The protrusion 4'formed on the shaft cylinder 4 by the axial movement of the shaft cylinder 4 presses the braking member 9 to couple the shaft cylinder 4 and the drive gear 8 with each other so that the friction transmission force can be adjusted. ing. At the outer end of the support shaft 3, a drag adjusting enemy 11 having an uneven portion 10 formed on the inner peripheral surface of the outer side is screwed so as to be able to move forward and backward, and inside thereof is a leaf spring or the like which is retained by a retaining ring 12. The elastic member 13 is fitted and the elastic member 13 presses the outer end of the barrel 4. On the other hand, a dish-shaped holding body 14 is detachably fixed to the outer end portion of the shaft cylinder 4 by a retaining ring 15, and an annular spring in which a central engaging projection 16 is projected on the peripheral surface in the holding body 14. 17 is locked, and the engaging projection 16 is engaged with the uneven portion 10 of the drag adjusting knob 11. Reference numeral 18 in the figure denotes a reverse rotation preventing ratchet that prevents the shaft cylinder 4 from rotating in the reverse direction. Therefore, the drag adjusting knob 11 is rotated so that the elastic member 13 presses the shaft cylinder 4, and the protrusion 4 ′ causes the braking member 9 to drive the drive gear 8.
If it is crimped on, the drag braking force will increase according to the degree of pressing, and if the drag adjusting knob 11 is rotated in the opposite direction, the drag braking force will decrease, and the rotation of the drag adjusting knob 11 will cause the uneven portion 10 to rotate. Are engaged with the engaging projections 16 of the annular spring 17 and are provided with moderation to prevent the relaxation thereof, the annular spring 17 is locked to the dish-shaped holding body 14, and the elastic member 13 is provided with a drag adjusting knob. The inside of the hand (11) is fitted and prevented from coming off, and each is unitized to facilitate the attachment / detachment operation. The embodiment shown in FIGS. 4 to 7 is one in which the rotation of the spool can be manually changed to high and low speeds, and the engagement rotation in the winding direction is performed on the outside of the shaft cylinder 4 via a one-way clutch 19. A handle rotating cylinder 20 provided with a movable handle 3 is provided, and a shaft cylinder 4 is rotatable inside and outside a planetary gear 21 that is axially supported by a front portion of the handle rotating cylinder 20 via a mounting member 20 '. The sun gear 22 and the inner toothed gear 23 which rotate integrally with the shaft cylinder 4 are engaged with each other, and the sun gear 22 is further provided with locking teeth 24. The locking teeth 24 are attached to the reel side plate 1. Operation lever 25 provided
The stopper claw 26 that is operated by is detachably provided. Therefore, when the handle 3 is rotated in the fishing line winding direction while the stopper claw 26 is engaged with the locking tooth 24 of the sun gear 22, the handle rotating cylinder 20 rotates, but the sun gear 22 rotates with the stopper claw 26. Since the planetary gears 21 are rotated, the planetary gears 21 are rotated to increase the speed of the inner tooth gears 23 to rotate the shaft cylinder 4, the drive gear 8 and the pinion 7 in order to rotate the spool 5 at high speed. . When the handle 3 is rotated in the fishing line winding direction with the stopper 26 removed from the locking teeth 24 of the sun gear 22, the shaft cylinder 4
Can rotate integrally with the handle rotating cylinder 20 via the one-way clutch 19, and the spool 5 can be wound at a low speed via the drive gear 8 and the pinion 7.
