Description

  The present invention relates to a fishing spinning reel, and more particularly to a fishing spinning reel in which a fishing line is wound on a spool that reciprocates by a rotation operation of a handle shaft attached to a reel body.

  In a reciprocating device that converts the rotational movement of the handle shaft of a fishing spinning reel into the longitudinal movement of the spool shaft, the handle is engaged with the sliding body attached to the rear end of the spool shaft and the guide groove of the sliding body. Some include an oscillating gear that transmits the rotational movement of the shaft to the sliding body (see, for example, Patent Document 1 and Patent Document 2).

  Such an oscillating gear of a spinning reel for fishing meshes with a small gear that is coaxially formed integrally with a handle shaft, and the rotation of the handle shaft is reciprocated in the front-rear direction via the oscillating gear and a sliding body. It is possible to reciprocate a spool shaft having a spool at the tip by this sliding body.

Further, in the body of the reel body, a rotating shaft cylinder having a pinion that is inserted into the spool shaft that moves back and forth and meshes with the drive gear on the handle shaft is provided by a support portion formed on the body of the reel body. It is supported rotatably.

  Normally, the small gear on the handle shaft that meshes with the oscillating gear prevents the contact portion or interference caused by the load during actual fishing and the dimensional error of the manufacturing surface with the support portion that rotatably supports the rotating shaft cylinder. In addition, it is necessary to provide a gap in the axial direction between them, and for this reason, a gear mechanism including a pinion and a drive gear integrally formed on the handle shaft, and meshing of a small gear on the handle shaft The reel body and the like that house and support the oscillating gear to be increased in size and weight. Further, in order to separate the portion of the handle shaft facing the small gear from the small gear, the support portion of the reel body is cut in an inclined manner on the small gear side, thereby supporting the pinion and the spool shaft. The support area is reduced and sufficient support strength cannot be obtained.

  The present invention has been made based on such circumstances, and an object of the present invention is to provide a fishing spinning reel in which a reel main body is formed in a compact structure and can be reduced in size and weight.

  The fishing spinning reel of the present invention that achieves the above object includes a gear provided on a handle shaft supported on the reel body, an interlocking gear supported on the reel body and rotating in mesh with the gear of the handle shaft, and the interlocking gear. And an engaging protrusion provided eccentrically from the center of rotation of the gear, and the engaging protrusion is engaged with an engaging groove of a sliding body attached to the rear portion of the spool shaft so that the rotational movement of the handle shaft is spooled. An oscillating mechanism that converts back and forth reciprocating motion of the shaft, and at least a rear portion of a pinion that is provided on the reel body and meshes with a drive gear provided on the handle shaft and integrally rotates a rotor having a fishing line guide portion and the spool shaft. A fishing spinning reel including a support portion that movably supports one of the gears provided on the handle shaft when viewed along the axial direction of the handle shaft. Place in a state overlapping with the portion of the base located on the reel body side of the lifting unit, characterized in that the the support portion and the handle shaft arranged close to each other.

  According to the spinning reel for fishing of the present invention, the gear meshed with the interlocking gear of the oscillating mechanism is meshed with the pinion in the vicinity of the support portion that movably supports the pinion and the spool shaft with respect to the reel body. It is possible to arrange a handle shaft provided with a drive gear to be operated, so that the winding shaft including the drive gear and the pinion and the spool shaft are reciprocated in the front-rear direction while maintaining the support strength of the support portion of the reel body. The reel main body that accommodates the moving oscillating mechanism is formed compactly, and the spinning reel for fishing can be made smaller and lighter.

  FIG. 1 shows a fishing spinning reel 10 according to a preferred embodiment of the present invention. The fishing spinning reel 10 includes a reel body 12 having a rigid structure, and is attached to a fishing rod via a rod attachment portion 14b formed at an end portion of a leg portion 14a extending upward from the reel body 12. . In the reel body 12, a winding drive mechanism for winding a fishing line around the spool 16 and a spool reciprocating device for reciprocating the spool back and forth are provided.

  The winding drive mechanism is preferably formed integrally with a handle shaft 20 that is rotatably supported in the reel body 12 and rotated by the handle 18, and a pinion 24 that meshes with the drive gear 22. Is provided. The pinion 24 extends in the front-rear direction orthogonal to the handle shaft 20 and is supported on the reel body 12 via a front bearing 26 and a rear bearing 28 so as to be rotatable. Provided in the department. A rotor 36 having a bail 32 and a fishing line guide 34 is integrally attached to the tip of the cylindrical shaft 30 and can rotate integrally with the cylindrical shaft 30 via the pinion 24.

  A spool shaft 38 passes through the cylindrical shaft 30 provided with the pinion 24 and extends in a direction perpendicular to the handle shaft 20. The spool shaft 38 is arranged concentrically with the cylindrical shaft 30 and can move back and forth along the direction perpendicular to the handle shaft 20 with respect to the cylindrical shaft 30 and the reel body 12. A spool 16 around which a fishing line is wound is attached to the tip of the spool shaft 38.

  An oscillating mechanism 40 that forms a spool reciprocating device that reciprocates the spool 16 in the front-rear direction has an interlocking gear 44 that meshes with a small gear 42 that is preferably formed integrally with the handle shaft 20, and the rotation of the interlocking gear 44. An engagement protrusion 46 that protrudes from the handle shaft 20, which is the central shaft, at a position eccentrically outward in the radial direction is formed in an engagement groove 50 of a sliding body 48 attached to the rear end portion of the spool shaft 38 with a screw 47. When engaged and the interlocking gear 44 rotates, the sliding body 48 can be guided in the front-rear direction along a guide rail (not shown). In such an oscillating mechanism 40, when the handle shaft 20 is rotated by the rotation operation of the handle 18, the interlocking gear 44 meshing with the small gear 42 on the handle shaft 20 rotates, and accordingly, the interlocking gear 44 is engaged. As the protrusion 46 rotates, the sliding body 48 reciprocates back and forth by the guide of the engaging groove 50 engaged with the engaging protrusion 46. Therefore, the spool shaft 38 attached to the sliding body 48 reciprocates (backs and forth) along the axial direction in the cylindrical shaft 30. The spool stroke, which is the longitudinal movement distance of the spool shaft 38, is determined by the amount of eccentricity of the engagement protrusion 46 from the rotation center axis of the interlocking gear 44 and the longitudinal distance of the engagement groove 50.

  In the fishing spinning reel 10 thus formed, when the handle 18 is rotated to rotate the handle shaft 20, the spool 16 is moved back and forth via the spool shaft 38 attached to the sliding body 48 of the oscillating mechanism 40. On the other hand, the rotor 36 is rotationally driven via the drive gear 22, the pinion 24, and the cylindrical shaft 30 of the winding drive mechanism. Therefore, the spool 16 is guided by the fishing line guide portion 34 and the fishing line is wound almost evenly.

  In the reel body 12, a reverse rotation prevention mechanism including a well-known one-way clutch 52 that prevents reverse rotation of the rotor 36 (rotation in the direction of feeding the fishing line from the spool) is disposed. Can be switched through a switching lever 54 provided on the rear end wall portion of the reel body 12, and the rotor 36 can be switched between a forward-reversible state and a forward-reversible and non-reversible state. Regardless of the state of the rotor 36, when the handle 18 is rotated in the forward direction (rotation in the direction of winding the fishing line on the spool), the bail 32 at the fishing line discharge position is shown in FIG. 1 can be returned to the fishing line winding position.

  2 and 3, the reel main body 12 is attached to the body portion 12a with a body portion 12a that forms an inner space 56 that opens to one side, and a plurality of screws, for example. And a lid 12b for closing the opening. A support portion 58 that supports the outer ring member of the rear bearing 28 formed of a ball bearing protrudes into the internal space 56 of the body portion 12a. The support portion 58 formed integrally with the body portion 12a has an axial hole 60 through which the spool shaft 38 is inserted, and a concave portion 62 that opens forward and accommodates the rear bearing 28 on the distal end side. The recess 62 has a larger diameter than the axial hole 60, and an annular surface 64 is formed between the inner peripheral surface of the recess 62 and the axial hole 60.

  The support portion 58 of this embodiment is provided with a collar 66 that slidably supports the spool shaft 38 in the axial direction. The collar 66 is formed of a low friction metal material or resin, and the like. The spool shaft 38 is slidably supported on the inner peripheral surface, and a slight gap is formed between the cylindrical shaft 30 and the spool shaft 38. The outer peripheral flange portion of the collar 66 is in contact with the inner peripheral surface of the axial hole 60, the inner peripheral surface of the recess 62, and the annular surface 64 therebetween, and is supported by the support portion 58. The support portion 58 to which the collar 66 is mounted in this way is formed with an annular groove that opens rearward, that is, toward the sliding body 48, by the axial hole 60, the collar 66, and the spool shaft 38. The rear bearing 28 accommodated in the concave portion 62 of the support portion 58 is positioned on the rear side in the axial direction by the support portion 58 via the outer ring member and the collar 66, and pinion via the front end side end surface of the inner ring member. The cylindrical shaft 30 having 24 is positioned on the rear side. Positioning of the front side of the cylindrical shaft 30 is performed by a nut 39 via a front bearing 26 (see FIG. 1). A slight gap is formed between the cylindrical shaft 30 and the spool shaft 38.

  In this way, the support portion 58 that supports the pinion 24 and the spool shaft 38 has a slight gap between the base portion located on the body 12a side of the reel body 12 and the small gear 42 provided on the handle shaft 20 described above. Thus, a notch 68 that avoids interference with the small gear 42 is formed. Since the notch 68 is formed only in the base portion of the support portion 58, that is, in the vicinity of the body portion 12 a and only in the upper corner of the rear portion as is apparent from FIG. 2, the pinion 24 and the spool shaft 38 It does not reduce the support strength. Further, the notch 68 may be machined not only when the body portion 12a is molded but also later.

  On the other hand, the handle shaft 20 provided with the small gear 42 is rotatably supported by a pair of bearings 74 and 76 respectively attached to the body portion 12a and the lid body 12b. Since the spool shaft 38 extending in a direction orthogonal to the handle shaft 20 is supported by a support portion 58 having a notch 68 formed in the base portion, when viewed along the axial direction of the handle shaft 20, the small gear 42. Is disposed so as to overlap with a part of the base portion of the support portion 58 located on the body portion 12a side of the reel body 12. Even if the handle shaft 20 is disposed close to the support portion 58, the small gear 42 does not interfere with the support portion 58. Thereby, while maintaining the spool stroke within a required range, the dimensions of the reel body 12 in the vertical direction and the front-rear direction can be made compact, and the size and weight can be reduced.

  Furthermore, through holes 70 and 72 through which the end portions of the handle shaft 20 are inserted are formed at positions where the body portion 12a and the lid 12b of the reel body 12 face each other, and the handle shaft 20 can be freely rotated through these through holes. Bearings 74 and 76 that are, for example, ball bearings that are supported on the housing are accommodated. Concave portions 78 and 80 are formed on the outer surfaces of the body portion 12a and the lid body 12b along the peripheral portions of the through holes 70 and 72 in which the bearings 74 and 76 are accommodated, and the end portion of the handle shaft 20 is inserted. Cover members 82 and 84 in which insertion holes 81 and 83 are formed are detachably attached to these recesses 78 and 80 by a plurality of set screws 77, for example.

  These cover members 82 and 84 are formed along the peripheral portions of the insertion holes 81 and 83 with annular grooves corresponding to the protrusions protruding from the peripheral portions of the through holes 70 and 72 of the body portion 12a and the lid body 12b. When the insertion holes 81 and 83 are arranged coaxially with the through holes 70 and 72, respectively, the protrusions and the annular grooves are fitted, and the through holes 70 and 72 and the insertion holes 81 and 83 are formed. The cover members 82 and 84 are positioned in a state where they are aligned coaxially.

  Thus, the cover members 82 and 84 attached to the reel body 12 act as retaining members for the bearings 74 and 76 that support the handle shaft 20, and position the bearings 74 and 76 with respect to the axial direction outward of the handle shaft 20. Do. When these cover members 82 and 84 are removed from the body portion 121a and the lid body 12b, the bearings 74 and 76 can be pulled out of the reel body 12 from the through holes 70 and 72. In a state where these bearings 74 and 76 are extracted from the through holes 70 and 72, the handle shaft 20 can be moved while being inclined in the radial direction. For this reason, even when the small gear 42 is formed integrally with the handle shaft 20, when the handle shaft 20 is assembled, the small gear 42 is easily inserted into the notch 68 of the support portion 58 formed integrally with the body portion 12a. Can be positioned.

  Therefore, when the cover members 82 and 84 are not provided, that is, when the bearings 74 and 76 are mounted or pulled out from the inner space 56 side, the small gear 42 is formed separately from the handle shaft 20 and is small. After the gear 42 is disposed in the notch 68 of the support portion 58, it is necessary to prevent the gear shaft 42 from being fitted to the handle shaft 20, whereas the bearing members 74 and 76 are attached to the reel body 12 by the cover members 82 and 84. Since the handle shaft 20 integrally formed with the small gear 42 meshing with the interlocking gear 44 of the oscillating mechanism 40 can be pulled out to the outside, the handle shaft 20 and the support portion 58 are arranged close to each other to reduce the size of the reel. It can be easily assembled into the main body 12.

  In addition, the body part 12a and the lid body 12b may be provided with, for example, an oiling hole (not shown) at a required position of a portion covered with the cover members 82 and 84. In this case, maintenance of the fishing spinning reel 10 is facilitated.
