  Usually, since a fishing spinning reel is used in a place where the use environment is severe, there is a problem that seawater, foreign matter, etc. are likely to adhere to and enter the inside of the push button described above during actual fishing. Therefore, in the configurations disclosed in Patent Document 1 and Patent Document 3 described above, the operation of the push button is hindered, the spool cannot be detached due to corrosion, or the components of the spool attachment / detachment device are fixed due to corrosion. And may be damaged by a decrease in strength.

  On the other hand, according to the configuration disclosed in Patent Document 2 described above, since the push button is covered by the elastic member, the above-described problems can be solved, but in practical use or moving Some fingers and other objects easily touch the elastic member, and the spool may be accidentally removed. Moreover, it is difficult to attach the elastic member to be the cover member to the front flange of the spool, and there is a problem that the attachment strength is not stable.

  The present invention has been made on the basis of the above-described problem. The spool attachment / detachment device can reliably prevent seawater and foreign matter from entering the spool attachment / detachment device by the seal member and can stably attach the seal member. It aims at providing the spinning reel for fishing provided with.

  In order to achieve the above-described object, a fishing spinning reel according to the present invention has a fishing line wound around a fishing line guide portion of a rotor that rotates in conjunction with a handle winding operation, and is supported by a reel body. A spool that is mounted on the spool shaft, and a spool that allows the spool to be removed from the spool shaft by releasing the locking state of the spool with respect to the spool shaft by pressing a push button provided on the front end side of the spool shaft An attaching / detaching device, which is attached to a braking force adjusting member that adjusts the braking force of the spool so as to cover the push button, and is elastically deformable that is latched and locked by a locking member from the inside of the spool. A sealing member that seals the inner peripheral surface of the through hole formed in the center of the braking force adjusting member and is positioned in the through hole. A pressing portion that covers the push button, and a locking portion that is integrally formed with the pressing portion and that is locked by the locking member on the back surface side of the braking force adjusting member. And

  In the above-described configuration, the elastically deformable seal member that covers the push button of the spool attaching / detaching device is retained and locked by the locking member from the inside of the spool, so that a stable mounting strength of the seal member can be secured, Since the push button to be pressed is sealed, entry of seawater, foreign matter, etc. into the spool attaching / detaching device is surely prevented. In particular, since the inner peripheral surface of the through-hole formed in the center of the braking force adjusting member is also sealed, entry of seawater, foreign matter, etc. into the spool attaching / detaching device is more reliably prevented.

  According to the present invention, a fishing spinning reel provided with a spool attaching / detaching device that can reliably prevent seawater, foreign matter and the like from entering the spool attaching / detaching device by the seal member and can stably attach the seal member can be obtained.

  Note that the driving force transmission mechanism 7 and the rotor brake mechanism 9 described above are well-known configurations, and thus detailed descriptions thereof are omitted.

  Inside the spool 3, a spool attaching / detaching device 10 for detachably attaching the spool 3 is disposed at the tip of the spool shaft 4. Further, in the present embodiment, a drag device (braking force adjusting device) 50 is disposed inside the spool 3 so that a predetermined braking force can be applied to the rotation of the spool 3. For this reason, a cylindrical shaft 11 that is inserted from the tip end side of the spool shaft 4 and is fixed to the spool shaft 4 is disposed at the shaft core portion of the spool 3. The spool 3 is attached to and detached from the shaft 11 and the spool shaft 4, and the drag device 50 is configured to apply a predetermined braking force to the spool 3 between the cylindrical shaft 11 and the spool 3. ing.

Next, the configurations of the spool attaching / detaching device 10 and the drag device 50 will be described with reference to FIGS.

  The spool shaft 4 is formed with a circumferential groove 4a on the distal end side, and a non-rotating pin 4b is formed on the proximal end side so as to project in the radial direction. The provided cylindrical shaft 11 is inserted. In this case, the cylindrical shaft 11 is locked to the spool shaft 4 at the circumferential groove 4a, and the detent pin 4b is engaged with the groove 12 formed at the proximal end of the cylindrical shaft 11. By doing so, the rotation is fixed to the spool shaft 4.

  The spool attaching / detaching device 10 includes a push button 13 disposed in an opening on the tip end side of the cylindrical shaft 11. The push button 13 protrudes from the opening end of the cylindrical shaft 11 and is pressed, and a semicircular shape extending toward the rear side so as to sandwich the spool shaft 4 when viewed in the axial direction. An engaging portion 13b is provided, and is held by an urging spring 14 disposed between a step portion 11a formed inside the tip end portion of the cylindrical shaft 11 so as to be capable of being pressed in the axial direction.

  The engaging portion 13b is formed with a taper 13c so as to gradually reduce the diameter toward the rear, and this taper 13c is a latch held by the cylindrical shaft 11 when the push button 13 is pushed. It can be engaged with the spring 15. In this case, as shown in FIGS. 8 (a) and 8 (b), the locking spring 15 extends in the diametrical direction with an arcuate portion 15a that slides in the circumferential direction around the outer peripheral portion of the cylindrical shaft 11. And a pair of substantially D-shaped members provided with a locking holding portion 15b located in the circumferential groove 4a.

  In the above-described configuration, when the push button 13 is pushed in against the biasing force of the biasing spring 14, the engaging portion 13b of the push button 13 at the position shown in FIGS. The taper 13c formed on the engaging portion 13b contacts the locking holding portion 15b, and moves the locking holding portion 15b downward as shown in FIG. 8B. When the latch holding portion 15b moves downward, the engagement relationship between the latch spring 15 and the circumferential groove 4a of the spool shaft 4 is released, and the spool 3 is detached from the spool shaft 4 together with the cylinder shaft 11. It becomes possible to remove.

  The drag device 50 is a drag knob unit body (which constitutes a braking force adjusting member) 51 disposed in a front collar 3a formed to project from the front end surface of the spool 3, and is pressed by the drag knob unit body. A braking member 52 that is biased and exhibits a predetermined drag force between the spool shaft 4 and the cylinder shaft 11 in a fixed state is provided.

  As shown in FIGS. 4 to 7, the drag knob knob unit 51 is a portion exposed at the front end surface of the spool, and includes a bank-shaped drag knob 55a formed to protrude on the front surface side, and a cylinder formed to protrude on the back surface side. It has a disc-shaped main body 55 provided with a portion 55b. A through hole 55c is formed at the center of the main body 55 so as to correspond to the position of the push button 13, and the through hole 55c passes through the central portion of the drag knob 55a. Further, a locking annular step portion 55d is formed on the inner peripheral surface of the through hole 55c in the drag knob 55a so as to be able to lock a seal member described later, and the cylindrical portion 55b has a connecting arm of the seal member. Slits 55e are formed at approximately 180 ° intervals so that the portion can be positioned. A pair of engaging protrusions 55f are formed on the outer periphery of the cylindrical portion 55b at a position orthogonal to the slit 55e.

  A seal member 57 formed of an elastically deformable material such as rubber is attached to the main body 55 from the back side (inner side). In this case, the seal member 57 seals the inner peripheral surface of the through hole 55c exposed on the surface side of the main body 55 so that the push button 13 located in the through hole 55c is not exposed.

  Here, the configuration of the seal member 57 of the present embodiment will be described with reference to FIGS. The seal member 57 is attached to the outer peripheral end of the back surface of the main body 55 by a ring-shaped locking plate (locking member) 58, and is locked against the outer peripheral area of the back surface of the main body 55. A portion (annular portion) 57a and a cap-shaped pressing portion 57b located at a through hole 55c portion in the drag knob 55a of the main body 55 are provided at the center portion thereof. The annular portion 57a and the pressing portion 57b are connected by a pair of connecting arm portions 57c formed at intervals of about 180 °.

  When the annular portion 57a is attached to the outer peripheral end of the back surface of the main body 55 by the ring-shaped locking plate 58, the sealing member 57 having such a shape has a slit in which the connecting arm portion 57c is formed in the cylindrical portion 55b. The cap-shaped pressing portion 57b is assembled to the main body 55 in a state where the cap-shaped pressing portion 57b is disposed in the through hole 55c formed in the central portion of the drag knob 55a. At this time, the lower circumferential edge 57d of the cap-shaped pressing portion 57b is locked to the locking annular step portion 55d formed in the through hole 55c, thereby stabilizing the mounting position and penetrating. The inner peripheral surface of the hole 55c is reliably sealed, and the entry of seawater, foreign matter, etc. into the spool attaching / detaching device 10 is more reliably prevented.

  Note that the locking portion for locking the seal member 57 from the inside of the main body 55 does not have to be formed in an annular shape as described above. Further, as described above, when the locking portion is formed in an annular shape that is attached to the outer peripheral portion of the back surface of the main body 55, the outer peripheral portion has a predetermined elasticity on the inner peripheral surface of the front collar 3a of the spool 3. It is preferable to form an annular contact portion 57e so as to make contact. By forming such an annular contact portion 57e, a gap generated between the front collar 3a and the drag knob unit body 51 is sealed, so that intrusion of seawater, foreign matter, etc. into the drag device 50 is prevented. can do.

  In the cylindrical portion 55 b of the main body 55, a nut 60 that is screwed with the screw portion 11 b formed at the distal end portion of the cylindrical shaft 11 is disposed in a state where the seal member 57 is attached and is prevented from rotating. . In this case, the threaded portion 60a of the nut 60 is formed to project forward from the portion 60b fitted and fixed to the cylindrical portion 55b, and is positioned in the through hole of the drag knob 55a. For this reason, the axial length of the drag knob unit body 51 can be shortened.

  And the bottomed cylinder 65 is attached to the main body 55 in a state where the drag spring 62 is interposed between the nut 60 and the drag unit body 51. The bottomed cylindrical body 65 is formed with a locking window portion 65a so that a pair of engaging protrusions 55f formed on the outer periphery of the cylindrical portion 55b of the main body 55 can be engaged and fixed. A moderating annular spring 65b is disposed so that a part thereof protrudes from the window 65a.

  The braking member 52 of the drag device 50 is pressed by a dish 70 that is in contact with the lower surface of the bottomed cylinder 65, and is between the cylinder shaft 11 in a fixed state and the spool 3 that is rotatable with respect to the cylinder axis. Thus, a predetermined drag force is generated. That is, by rotating the drag knob 55 a, the nut 60 moves in the axial direction on the cylinder shaft 11, and is predetermined with respect to the braking member 52 via the drag spring 62, the bottomed cylinder 65, and the dish body 70. A desired braking force is applied to the spool 3. The moderating annular spring 65b described above is engaged with the circumferential uneven portion 70a of the dish body 70, and a clicking sound is generated in accordance with the rotation operation of the drag knob 55a.

  According to the spinning reel having the above-described configuration, the seal member 57 can reliably prevent adhesion and intrusion of seawater, foreign matter, slime, and the like to the spool attaching / detaching device 10 even in a fishing place where the usage environment is severe. Stable attachment / detachment performance of the spool can be obtained. Since the sealing member 57 is configured to be retained and locked by the locking member 58 from the inside so that the mounting portion is not exposed on the outer surface, the sealing member 57 can be securely and easily mounted and has a stable mounting strength. can get. The seal member 57 may be configured to be fixed to the back surface side of the main body 55 by adhesion or the like without using the locking member 58.

  Further, since the seal member 57 is exposed only in the area covering the pressing operation portion 13a of the push button 13, and the exposed portion on the front surface of the spool is configured to be the minimum necessary, it is in practical use or moving. In addition, it is possible to prevent the spool 3 from being accidentally removed by accidentally hitting a finger or other object of the hand.

  Further, in the above-described configuration, the drag device 50 is provided on the front end side of the spool 3, and the seal member 57 is integrated with the drag knob 55a in a state where the drag knob 55a of the drag device is screwed to the threaded portion 11b on the spool shaft. As a result, the drag device for adjusting the braking force can be waterproofed and dustproof, and can be handled easily in the manufacturing stage. Since the seal member 57 is exposed only in the center portion of the protruding drag knob 55a, it is possible to prevent the spool from being accidentally detached during the operation of the drag knob.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to an above-described structure, It can change variously. For example, the above-described seal member 57 may be formed so as to be attached to the inside of the spool so that the pressing operation portion of the push button of the spool attaching / detaching device can be sealed. Is possible.

  Further, the present invention can be applied to various forms of spinning reels. For example, in the configuration described above, the spool attaching / detaching device and the drag device are integrally incorporated in the spool front end, but the drag device may not be provided in the spool front end. In this case, the above-described cylindrical shaft 11 that is fixed to the spool shaft 4 is not necessary.
