Description

  TECHNICAL FIELD The present invention relates to a fishing reel drag force adjusting device and a fishing reel including the same, and more particularly to an improvement of a drag force adjusting device for preventing cutting of a fishing line, and fishing with the improved drag force adjusting device. Related to reels.

  2. Description of the Related Art Conventionally, a fishing force reel is usually equipped with a drag force adjusting device in order to prevent the fishing line from being cut when a large tensile force is applied to the fishing line due to a strong pulling force or rapid reversal of the fish. FIG. 1 shows a fishing spinning reel equipped with a conventional drag force adjusting device. FIG. 2 is an exploded perspective view showing the conventional drag force adjusting device.

  As shown in FIG. 1, the conventional drag force adjusting device 16 is interlocked with one end 131 of a non-rotatable spool shaft 13 that reciprocates on its axis by the operation of a handle 15 and the spool shaft 13. It is mounted between a spool 14 for spooling that is rotatably provided at the one end 131 so as to reciprocate. A cross section of the one end 131 of the spool shaft 13 is non-circular.

  As shown in FIGS. 1 and 2, the drag force adjusting device 16 includes a plurality of lining pieces 160, 161, a plurality of drag pieces 162, and a friction force adjusting knob 163. The plurality of lining pieces 160 and 161 and the plurality of drag pieces 162 are arranged in a series of crossing each other.

  The plurality of lining pieces 160 and 161 are divided into a part 160 having a non-circular center through hole 1601 and a part 161 having a circular center through hole 1611. Each lining piece 160 having the non-circular center through hole 1601 is externally fitted and fixed to the one end 131 of the spool shaft 13 so as to reciprocate together with the spool shaft 13. Each lining piece 161 having the circular center through hole 1611 is rotatably attached around the one end 131 of the spool shaft 13 and is formed on the outer peripheral edge of the spool 14 on the inner peripheral surface of the spool 14. A plurality of engagement protrusions 1612 that engage with the plurality of engagement grooves 144 are formed.

  Each of the plurality of drag pieces 162 has a rough surface on both sides, has a circular center through hole 1621, and is in contact with the corresponding lining pieces 160 and 161 in a face-to-face manner. 13 around the one end 131 is rotatably provided.

  The frictional force adjusting knob 163 is screwed to a free end portion of the spool shaft 13, and presses and fixes the plurality of lining pieces 160, 161 and the plurality of drag pieces 162 from the axial direction, It adjusts the tightening force between them.

  As a result, when the fish runs, when the spool 14 is slip-rotated in the thread feeding direction with respect to the spool shaft 13, the engagement between the plurality of engagement grooves 144 and the plurality of engagement protrusions 1612 is performed. As a result, the plurality of lining pieces 161 having the circular center through hole 1611 rotate together with the spool 14. The lining piece 161 can prevent slipping of the fishing line by braking the slip rotation of the spool 14 with respect to the spool shaft 13 by friction with the plurality of drag pieces 162 and thereby releasing the fishing line in a limited manner. . Further, by adjusting the tightening force between the plurality of lining pieces 160 and 161 and the plurality of drag pieces 162 with the friction force adjusting knob 163, the strength of the friction force can be adjusted.

  When the drag force adjusting device 26 having the same configuration as described above is applied to a fishing casting reel, as shown in FIGS. 3 and 4, the drive shaft 23 that rotates on the axis thereof by operating the handle 25, A drive gear 22 that rotates in conjunction with the drive shaft 23 and drives the rotation of the spool 24 is provided. Each lining piece 260 having the non-circular center through hole 2601 is externally fitted and fixed to the drive shaft 23 so as to rotate together with the drive shaft 23 having a non-circular cross section. Each lining piece 261 having the circular center through hole 2611 is engaged with an engagement groove 221 formed on the inner peripheral surface of the drive gear 22 by the engagement protrusion 2612 so as to rotate together with the drive gear 22. Are provided to be rotatable around the drive shaft 23.

  The plurality of drag pieces 262 are rotatably provided around the drive shaft 23 so as to abut the corresponding lining pieces 260 and 261 in a face-to-face manner. The frictional force adjusting knob 263 is screwed to the free end of the drive shaft 23.

  Accordingly, when the fish runs, when the spool 24 of the casting reel is slip-rotated in the thread feeding direction, the drive gear 22 rotates in the thread feeding direction with respect to the drive shaft 23. Then, the plurality of lining pieces 261 having the circular center through hole 2611 rotate together with the drive gear 22 by the engagement of the plurality of engagement grooves 221 and the plurality of engagement protrusions 2612. In addition, the lining piece 261 is rubbed with the plurality of drag pieces 262 to brake the rotation of the drive gear 22 relative to the drive shaft 23 and further brake the slip rotation of the spool 24 to restrict the fishing line. Can be issued.

  However, the conventional drag force adjusting devices 16 and 26 have a function of causing the spools 14 and 24 to slip-rotate in the thread feeding direction while frictionally braking, but the plurality of drag pieces 162 and 262 may be the spool shaft 13 or the like. Since the plurality of lining pieces 161 and 261 having the circular center through holes 1611 and 2611 are rubbed with the plurality of drag pieces 162 and 262, the drag is provided around the drive shaft 23. Since the pieces 162 and 262 may rotate with the rotation of the lining pieces 161 and 261, the generation of frictional force becomes unstable. As a result, since the braking effect is poor, there is a problem in that the frictional force adjusting knobs 163 and 263 must be frequently tightened to obtain a desired frictional force.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a fishing reel drag force adjusting device and a fishing reel including the same, in which the generation of frictional force is stable and the braking effect is good.
