Japanese Patent No. 3565562 Japanese Patent No. 3585474

  When the rear end of the spool shaft is applied to the recess of the slider and fixed with screws, or when the rear end of the spool shaft is fitted into the D-shaped hole of the slider, it slides with the spool shaft. It is difficult to determine the position and posture of the spool shaft and the slider with high accuracy due to the effect of the fitting gap with the child. In addition, in order to mold the slider with a mold, a recess taper is often provided in the recess or D-shaped hole. Due to the effect of this taper, the position and orientation of the spool shaft and the slider are highly accurate. It is difficult to determine.

  If the accuracy of the position and posture of the spool shaft and the slider is not good, the sliding resistance of the spool shaft and the frictional resistance in the spool reciprocating mechanism increase. When these resistances increase, it becomes difficult to improve the smoothness of the reciprocating motion of the spool shaft.

  Further, when the rear end portion of the spool shaft is applied to the recessed portion of the slider and fixed with screws, or when the rear end portion of the spool shaft is fitted into the D-shaped hole of the slider, the slider It becomes a comparatively large thing which surrounds the edge part of a spool axis | shaft along the circumferential direction. Since the slider reciprocates within the reel body, the larger the slider, the larger and heavier the reel body that houses the slider.

  An object of the present invention is to obtain a fishing spinning reel that can improve the smoothness of reciprocating movement of a spool shaft and can reduce the size and weight of a reel body.

  In order to achieve the above object, a fishing spinning reel according to one aspect of the present invention has a reel body on which a handle is mounted and a spool fixed to the reel body so as to be linearly reciprocable. A fishing spinning reel provided with a spool shaft and a spool reciprocating mechanism that is provided on the reel body and converts a rotational movement of the handle into a reciprocating motion of the spool shaft, The mechanism includes a slider that reciprocates within the reel body along the axial direction of the spool shaft along with the rotational movement of the handle, and that opposes a part of the end of the spool shaft along the circumferential direction. .

  A mounting plane facing the spool shaft is formed on the slider. A locking plane facing the mounting plane of the slider is formed at the end of the spool shaft facing the slider. The spool shaft is fixed to the slider by bringing the locking plane into contact with the mounting plane.

  According to the present invention, since the position and posture of the spool shaft and the slider can be determined with high accuracy, the smoothness of the reciprocating motion of the spool shaft is improved. Furthermore, since the slider can be reduced in size, the reel body can be reduced in size and weight.

  Embodiments of the present invention will be described below with reference to FIGS. First, a fishing spinning reel 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

  As shown in FIG. 1, a fishing spinning reel 1 includes a reel body 2, a rotor 3, and a spool 4. The reel body 2 is made of a lightweight metal material such as a magnesium alloy or an aluminum alloy. The reel body 2 has a leg portion 5 extending upward, and a rod attachment portion 5a formed on the upper end portion of the leg portion 5 is fixed to a reel seat of a fishing rod (not shown).

  The reel body 2 includes a reel body 6 integrated with the legs 5. A storage chamber 7 is provided inside the reel body 6. At the front end of the reel body 6, for example, a rotating shaft cylinder 11 that is rotatably supported by the reel body 6 via a plurality of bearings 10 is provided. The rotating shaft cylinder 11 extends in the front-rear direction (the horizontal direction in FIG. 1) of the reel body 2, and its front half projects from the front end of the reel body 6 to the outside of the reel body 6. A pinion gear 12 is integrally formed at one end of the rotating shaft cylinder 11. The pinion gear 12 is formed at the rear end portion of the rotating shaft cylinder 11 extending into the storage chamber 7 and is exposed in the storage chamber 7. For convenience of explanation, the front, rear, left, and right are defined in this specification when the spool 4 is viewed from the reel body 2.

  As shown in FIG. 1, the rotor 3 is attached to the front portion of the rotating shaft cylinder 11 protruding from the front end portion of the reel body 6 in a state in which the rotor 3 is prevented from rotating and is fastened and fixed with a nut. The rotor 3 is coaxially fixed to the rotating shaft 11 and is rotatable with respect to the reel body 2.

  The rotor 3 has a pair of arms 13. The arm 13 protrudes from the rotor 3 toward the front of the fishing spinning reel 1. A fishing line guide device 14 is provided between the distal ends of the arms 13. The fishing line guide device 14 is for guiding the fishing line to the spool 4 and includes a bail 15 straddling between the pair of arms 13.

  As shown in FIG. 1, a fishing spinning reel 1 includes a spool shaft 21 supported on a reel body 2 so as to be linearly reciprocable. The rotating shaft cylinder 11 has an insertion hole 11 a through which the spool shaft 21 passes along the front-rear direction of the reel body 2. The spool shaft 21 is coaxially inserted into the insertion hole 11 a of the rotating shaft cylinder 11, passes through the rotating shaft cylinder 11, and extends from the inside of the reel body 2 to the outside of the reel body 2.

  The spool shaft 21 is slidably supported in the insertion hole 11 a of the rotary shaft cylinder 11 and can reciprocate along the front-rear direction of the reel body 2. A rear end portion 21 a as a first end portion of the spool shaft 21 extends into the accommodation chamber 7.

  The spool 4 is attached to the front end portion 21 b as the second end portion of the spool shaft 21. The spool 4 can reciprocate together with the spool shaft 21 along the front-rear direction of the reel body 2. That is, the spool 4 can move forward and backward with respect to the reel body 2. The spool 4 has a small-diameter portion 4a serving as a fishing-line winding body portion around which the fishing line is wound, and a large-diameter portion 4b positioned behind the small-diameter portion 4a.

  As shown in FIG. 1, the accommodation chamber 7 accommodates a drive gear 23 that drives and rotates the rotor 3. As shown in FIG. 2, the drive gear 23 includes a gear body 23a and a boss portion 23b serving as a drive cylinder shaft extending from the gear body 23a in the width direction of the reel body 2 (lateral direction in FIG. 2). The gear main body 23 a is arranged in a substantially left half region of the storage chamber 7.

  The reel body 2 includes bearings 24 on a cover plate 6a and a right side wall 6b that close the opening of the reel body 6, respectively. The boss portion 23 b of the drive gear 23 is inserted into the plurality of bearings 24 and is rotatably supported by the reel body 2. That is, the boss portion 23 b extends between the bearing 24 of the cover plate 6 a of the reel body 6 and the bearing 24 of the right side wall 6 b and crosses the storage chamber 7 in the width direction of the reel body 2. As shown in FIG. 1, the boss portion 23 b is located behind the pinion gear 12. The drive gear 23 integrated with the boss portion 23b meshes with the pinion gear 12 described above.

  As shown in FIGS. 1 and 2, a handle 26 is attached to the reel body 2. A handle shaft 27 is provided at the base end portion of the handle 26. The handle shaft 27 extends inside the storage chamber 7. The handle shaft 27 is fitted to the inside of the boss portion 23b of the drive gear 23, and rotates integrally with the drive gear 23 by engaging with the inner surface of the boss portion 23b. The handle shaft 27 extends in the width direction of the reel body 2 so as to be orthogonal to the spool shaft 21.

  When the angler turns the handle 26 by hand, the drive gear 23 rotates through the handle shaft 27 and the boss portion 23b. Since the drive gear 23 meshes with the pinion gear 12 of the rotating shaft cylinder 11, the rotating shaft cylinder 11 is rotated via the pinion gear 12. Thereby, the rotor 3 fixed to the rotating shaft cylinder 11 rotates in the direction which winds up a fishing line.

  As shown in FIG. 1, a fishing spinning reel 1 is provided on a reel body 2 and has a spool reciprocating mechanism 29 (so-called oscillating mechanism) that converts the rotational movement of a handle 26 into reciprocating movement of a spool shaft 21. Prepare. The spool reciprocating mechanism 29 according to this embodiment is a so-called worm shaft system. The spool reciprocating mechanism 29 includes a relay gear 31, a worm shaft 32, and a slider 33 that are housed in a lower region on the opposite side of the leg portion 5 of the housing chamber 7.

  As shown in FIG. 1, the worm shaft 32 extends in parallel with the spool shaft 21 and is rotatably supported by the reel body 2 via a bearing 34. On the peripheral surface of the worm shaft 32, a groove 32a in which a right spiral groove and a left spiral groove are continuous with each other is provided. As shown in FIG. 2, the worm shaft 32 is disposed below the spool shaft 21.

  As shown in FIG. 1, a relay gear 31 is attached to the front end portion of the worm shaft 32. The relay gear 31 meshes with the pinion gear 12. Thus, when the pinion gear 12 is rotated, the pinion gear 12 rotates the worm shaft 32 via the relay gear 31.

  The slider 33 reciprocates back and forth within the reel body 2 along the axial direction of the spool shaft 21 as the handle 26 rotates. Specifically, as shown in FIG. 2, the slider 33 includes a slider body 36 and an engagement pin attachment portion 37. The slider body 36 is orthogonal to the spool shaft 21 in the reel body 2, extends in the vertical direction below the spool shaft 21 on the opposite side of the leg 5, and extends from the side of the worm shaft 32 to the side of the spool shaft 21. Are provided.

  The slider body 36 surrounds the circumferential surface of the worm shaft 32 from the left side over a semicircular circumference. The engaging pin mounting portion 37 is integrally formed with the slider body 36 and faces the worm shaft 32 from the opposite side of the slider body 36. An engaging pin 39 is rotatably accommodated and held in the engaging pin mounting portion 37. The engagement pin 39 is engaged with the groove 32 a of the worm shaft 32. Accordingly, when the worm shaft 32 rotates, the engagement pin 39 slides along the groove 32 a of the worm shaft 32, and the slider 33 reciprocates back and forth along the worm shaft 32.

As shown in FIG. 3, the upper end portion of the slider 33 is connected to the rear end portion 21 a of the spool shaft 21. Hereinafter, the fixing structure between the slider 33 and the spool shaft 21 will be described in detail.
The slider 33 faces a part along the circumferential direction of the rear end portion 21 a of the spool shaft 21 without surrounding the entire circumference of the rear end portion 21 a of the spool shaft 21. In the present embodiment, the slider 33 is opposed to the peripheral surface of the rear end portion 21a of the spool shaft 21 from the left side and the lower side, for example, and does not surround the upper side and the right side. However, the peripheral surface of the spool shaft 21 facing the slider 33 is not limited to the above example, and the slider 33 may be opposed to the spool shaft 21 from above or from the right side.

  As shown in FIG. 3, the slider 33 is formed with a mounting plane 41 facing the rear end portion 21 a of the spool shaft 21. The mounting plane 41 is formed, for example, on the right side surface of the slider 33, extends along the front-rear direction and the vertical direction of the reel body 2, and faces the spool shaft 21 from the left side. An example of the mounting plane 41 is provided from the front edge to the rear edge of the slider 33 along the axial direction of the spool shaft 21.

  On the other hand, a locking plane 42 that faces the mounting plane 41 of the slider 33 is formed at the rear end 21 a of the spool shaft 21. The locking plane 42 is formed, for example, by cutting out a part of the rear end portion 21a of the spool shaft 21. An example of the locking plane 42 is formed over the entire area of the spool shaft 21 that faces the mounting plane 41.

  As shown in FIG. 3, the spool shaft 21 is further provided with a screw hole 44 that opens toward the slider 33 and extends in the width direction of the reel body 2. For example, two screw holes 44 are provided, and the two screw holes 44 are arranged side by side along the axial direction of the spool shaft 21 (see FIG. 1). A female screw is formed in the screw hole 44. On the other hand, the slider 33 is formed with two screw insertion holes 45 facing the two screw holes 44.

  As shown in FIG. 3, the spool shaft 21 is fixed to the slider 33 with, for example, two screws 46 with the locking plane 42 of the spool shaft 21 coming into contact with the mounting plane 41 of the slider 33. The That is, in a state in which the locking plane 42 of the spool shaft 21 is applied to the mounting plane 41 of the slider 33, the screw 46 is engaged with the screw hole 44 from the screw insertion hole 45, so that the spool shaft 21 is engaged. Fasten to 33. Thus, the spool shaft 21 and the slider 33 are connected to each other without the spool shaft 21 being fitted into the slider 33.

  On the other hand, as shown in FIG. 3, the mounting plane 41 of the slider 33 has a lower edge portion 41 a and an upper edge portion 41 b that extend parallel to the axial direction of the spool shaft 21. The slider 33 includes a wall portion 48 that extends downward from the spool shaft 21 from, for example, the lower edge portion 41 a of the mounting plane 41. A support plane 49 is formed on the upper surface of the wall portion 48. The support plane 49 is provided adjacent to the lower edge portion 41 a of the mounting plane 41 and faces the spool shaft 21 from a direction different from that of the mounting plane 41. The support plane 49 extends in the horizontal direction as a part of the upper surface of the slider 33 formed below the mounting plane 41 and faces the spool shaft 21 from below.

  The support plane 49 extends, for example, in a direction orthogonal to the mounting plane 41. An example of the support plane 49 is provided from the front edge to the rear edge of the slider 33 along the axial direction of the spool shaft 21. On the other hand, the locking plane 42 has a lower edge portion and an upper edge portion that respectively extend along the axial direction of the spool shaft 21. The support plane 49 extends in the axial direction of the spool shaft 21 along the lower edge portion of the locking plane 42 of the spool shaft 21 and makes line contact with the lower edge portion of the locking plane 42. That is, the support plane 49 abuts on the lower edge portion of the locking plane 42 from a direction different from the mounting plane 41 (a direction different from 90 degrees in this embodiment), and supports the spool shaft 21 from below.

  Note that the mounting plane 41 and the support plane 49 may be formed, for example, by molding using a mold. However, if formed by, for example, cutting, the processing accuracy of the plane becomes high, and the spool shaft 21 or the sliding plane It is easy to determine the position and posture of the child 33 with high accuracy.

  As shown in FIG. 3, an upper surface 50 that extends toward the opposite side of the spool shaft 21 is formed from the upper edge portion 41 b of the mounting plane 41. That is, the upper side of the mounting plane 41 is open. The slider 33 having such a shape can be molded by a mold without providing a punch taper, for example. For this reason, even when the slider 33 is molded by a mold, it is easy to ensure the processing accuracy of the mounting plane 41 and the support plane 49, and the position and posture of the spool shaft 21 and the slider 33 can be determined with high accuracy.

  When the handle 26 is operated in the direction of winding the fishing line, the rotation of the drive gear 23 is transmitted to the worm shaft 32 via the relay gear 31, and the worm shaft 32 rotates. By the rotation of the worm shaft 32, the slider 33 having the engagement pin 39 engaged with the groove 32 a of the worm shaft 32 reciprocates back and forth with respect to the reel body 2. As described above, the rotational motion of the worm shaft 32 is converted into the reciprocating linear motion by the engagement between the groove 32 a and the engagement pin 39 and transmitted to the slider 33. Since the slider 33 is fixed to the rear end portion 21 a of the spool shaft 21, the spool shaft 21 reciprocates in the front-rear direction of the reel body 2 together with the spool 4.

  Next, a pair of guide portions 52 and 53 that slide and guide the slider 33 along the axial direction of the spool shaft 21 will be described. An example of the guide portions 52 and 53 is a pillar (that is, a guide shaft) provided in the reel body 2 and extending in parallel with the axial direction of the spool shaft 21. As shown in FIG. 1, the guide portions 52 and 53 are installed between the front and rear portions of the reel body 2, for example.

  As shown in FIG. 2, the slider 33 is provided with support portions 54 and 55 in which through holes through which guide portions 52 and 53 that are pillars are inserted are formed. As shown in FIG. 1, the guide portions 52 and 53 penetrate the support portions 54 and 55 and support the slider 33 so as to be slidable. In addition, the guide parts 52 and 53 are not limited to pillars, and may be, for example, guide parts including convex parts and concave parts provided integrally on the bottom wall or side wall of the reel body 6.

  As shown in FIG. 2, the spool shaft 21 according to the present embodiment is not surrounded by the slider 33, and most of the spool shaft 21 except the locking plane 42 is exposed in the storage chamber 7. A region that does not interfere with the drive gear 23, the worm shaft 32, and the like exists between the peripheral surface of the spool shaft 21 that is off the locking plane 42 and the right side wall 6 b of the reel body 6.

  As shown in FIG. 2, the first guide portion 52 is disposed in a region between the slider 33 and the right side wall 6 b of the reel body 6. That is, the first guide portion 52 is disposed in a region adjacent to the space between the peripheral surface of the spool shaft 21 that is off the locking plane 42 and the right side wall 6b of the reel body 6, and the spool that is off the locking plane 42. It faces the peripheral surface of the end of the shaft 21.

  On the other hand, the second guide portion 53 is provided so as to penetrate the lower end portion of the slider 33. The second guide portion 53 is provided on the side opposite to the first guide portion 52 with the worm shaft 32 as a base point. That is, the first guide part 52 and the second guide part 53 are arranged on both sides of the worm shaft 32 so as to sandwich the worm shaft 32 therebetween.

  According to the fishing spinning reel 1 having such a configuration, the smoothness of the reciprocating motion of the spool shaft 21 can be improved. In other words, the mounting plane 41 is formed on the slider 33, the locking plane 42 is formed on the spool shaft 21, and the spool plane 21 is brought into contact with the mounting plane 41 by making the locking plane 42 contact the mounting plane 41. When fixed, it is possible to avoid a decrease in assembly accuracy due to the effect of the above-mentioned fitting gap and the influence of the taper.

  That is, according to such a configuration, the positions and postures of the spool shaft 21 and the slider 33 can be determined with high accuracy. Therefore, for example, the sliding resistance between the spool shaft 21 and the rotating shaft cylinder 11 and the frictional resistance in the spool reciprocating mechanism 29 can be kept small, and the smoothness of the reciprocating motion of the spool shaft 21 is improved.

  In particular, in a spinning reel provided with pillars and other shaped guide portions 52 and 53, if the accuracy of the position and posture of the slider 33 is not good, there is a frictional resistance between the slider 33 and the guide portions 52 and 53. Arise. On the other hand, if the position and orientation of the slider 33 can be determined with high accuracy as in the present embodiment, the parallelism between the slider 33 and the guide portions 52 and 53 can be maintained with high accuracy. The sliding resistance between the slider 33 and the guide portions 52 and 53 can be kept small.

  Further, when the worm shaft type spool reciprocating mechanism 29 as in the present embodiment is provided, if the accuracy of the position and orientation of the slider 33 is not good, the engaging pin 39 of the slider 33 is connected to the worm shaft 32. The frictional resistance in the spool reciprocating mechanism 29 may increase because the groove 32a disengages from the groove 32a and rides on the peripheral surface of the worm shaft 32. On the other hand, if the position and orientation of the slider 33 can be determined with high accuracy as in the present embodiment, the engagement pin 39 of the slider 33 slides along the groove 32a of the worm shaft 32. The frictional resistance in the spool reciprocating mechanism 29 can be kept small.

  Further, according to the fishing spinning reel 1 having such a configuration, the smoothness of the reciprocating motion of the spool shaft 21 is improved, and at the same time, the reel body 2 can be reduced in size and weight. That is, when the locking plane 42 is brought into contact with the mounting plane 41 and the spool shaft 21 is fixed to the slider 33, the slider 33 does not surround the entire circumference of the spool shaft 21 and the rear end portion 21 a of the spool shaft 21. It only opposes a part along the circumferential direction. That is, it is possible to reduce the thickness of the spool shaft fixing portion of the slider 33 as compared with a slider having a hollow portion or a D-shaped hole.

  If the slider 33 can be reduced in size, the size of the accommodation chamber 7 that accommodates the slider 33 in a reciprocating manner can be reduced. Thereby, size reduction and weight reduction of the reel main body 2 can be achieved.

  When the support surface 49 is provided on the slider 33, the position and posture of the spool shaft 21 are defined from two directions. Thereby, the accuracy of the position and posture of the spool shaft 21 is further increased. In addition, the slider 33 can be more reliably prevented from rotating with respect to the spool shaft 21. Further, since the spool shaft 21 can be easily aligned by bringing the spool shaft 21 into contact with the support flat surface 49, the fishing spinning reel 1 with good assemblability is provided.

  When the support plane 49 is provided on the slider 33, the parallelism of the axis of the spool shaft 21 with respect to the reciprocating direction of the spool shaft 21 can be determined with high accuracy. Further, when the support surface 49 is provided on the slider 33, even if the spool shaft 21 is fixed to the slider 33 with a single screw 46, the posture deviation of the spool shaft 21 can be suppressed.

  The fact that the guide portion 52 faces the peripheral surface of the end of the spool shaft 21 that is out of the locking plane 42 means that the guide portion 52 is arranged in an empty space in the storage chamber 7 that appears due to the downsizing of the slider 33. That is. As described above, when the guide portion 52 is provided by effectively utilizing the empty space due to the downsizing of the slider 33, the mounting efficiency in the reel body 2 is increased, and the reel body 2 can be downsized.

  For example, by using the empty space, the first and second guide portions 52 and 53 can be arranged side by side in a substantially vertical direction. If the first and second guide portions 52 and 53 can be arranged side by side in a substantially vertical direction, the reel body 2 can be thinned in the lateral width direction.

  Further, in the present embodiment, the first and second guide portions 52 and 53 are arranged on both sides of the worm shaft 32 so as to sandwich the worm shaft 32 therebetween by using the empty space. If the first and second guide portions 52 and 53 can be disposed on both sides of the worm shaft 32, rattling of the slider 33 along the rotation direction of the worm shaft 32 can be further suppressed.

  The locking plane 42 is not limited to the right side surface of the slider 33 but may be the left side surface, upper surface, or lower surface of the slider 33. The spool shaft 21 may be formed with an attachment plane 41 that faces the locking plane 42 of the slider 33 and may be brought into contact with the slider 33 from the left, above, or below.

  However, if the latching plane 42 is provided on the right side or the left side of the slider 33 and the spool shaft 21 is fastened to the slider 33 along the horizontal direction, it is advantageous in reducing the size of the reel unit 2. It is. That is, when the mounting plane 41 expands along the vertical direction, the lateral width of the slider 33 can be reduced, so that the reel body 2 can be thinned in the lateral width direction.

  When the spool shaft 21 is fastened to the slider 33 along the horizontal direction, the upper end of the slider 33 is the same as the upper end of the spool shaft 21 or slightly higher than the upper end of the spool shaft 21. Can be paid. If the upper end of the slider 33 can be set near the upper end of the spool shaft 21, the interval (so-called offset) between the spool shaft 21 and the handle shaft 27 can be reduced. This contributes to downsizing and improving the rotation performance of the fishing spinning reel 1.

  In this embodiment, the spool shaft 21 is provided with the screw hole 44 and the slider 33 is provided with the screw insertion hole 45. Instead, the spool shaft 21 is provided with the screw insertion hole 45. Of course, the slider 33 may be provided with a screw hole 44 and screwed from the spool shaft 21 side.

  Next, a modification of the fishing spinning reel 1 according to the first embodiment of the present invention will be described with reference to FIG. As shown in FIG. 4, the slider 33 according to this modification includes another wall portion 56 that extends from the upper edge portion 41 b of the mounting plane 41 to above the spool shaft 21. On the lower surface of the wall portion 56, another support plane 57 that is provided adjacent to the upper edge portion 41 b of the mounting plane 41 and faces the spool shaft 21 from a direction different from the mounting plane 41 is formed.

  The other support plane 57 extends, for example, along a direction orthogonal to the mounting plane 41. The other support plane 57 abuts on the upper edge portion of the locking plane 42 of the spool shaft 21 and supports the upper edge portion 41b from above. According to such a slider 33, the spool shaft 21 is fixed with higher accuracy.

  Next, a fishing spinning reel 61 according to a second embodiment of the present invention will be described with reference to FIGS. In addition, the structure which has the same function as the spinning reel 1 for fishing which concerns on 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits the description. The fishing spinning reel 61 according to the second embodiment is different in the configuration of the spool reciprocating mechanism from the first embodiment, and the basic configuration of the fishing spinning reel is the same.

  As shown in FIG. 5, the relay gear 62 according to the present embodiment is integrally provided on the outer periphery of the boss portion 23 b of the drive gear 23. The relay gear 62 rotates together with the boss portion 23b. The spool reciprocating mechanism 29 according to this embodiment is a so-called idle gear system. The spool reciprocating mechanism 29 includes an oscillating drive gear 63 and a slider 33 that are housed in the housing chamber 7.

  The oscillating drive gear 63 is rotatably supported on the inner surface of the right side wall 6 b of the reel body 6 via a screw 65. The oscillating drive gear 63 is located behind the handle shaft 27 and is interposed between the rear end portion 21 a of the spool shaft 21 and the right side wall 6 b of the reel body 6. The oscillating drive gear 63 meshes with the relay gear 62.

  The oscillating drive gear 63 has a cylindrical convex portion 63a on the end surface on the spool shaft 21 side. The convex portion 63 a is provided at a position eccentric from the rotation center of the oscillating drive gear 63. For this reason, the convex part 63a revolves around the screw 65 when the oscillation drive gear 63 rotates. The slider 33 extends in the height direction of the reel body 2. The slider 33 is disposed between the oscillating drive gear 63 and the drive gear 23.

  As shown in FIG. 6, the slider 33 faces a part along the circumferential direction of the rear end portion 21 a of the spool shaft 21. As in the first embodiment, a mounting plane 41 and a support plane 49 are formed on the slider 33. On the other hand, a locking plane 42 is formed on the circumferential surface of the spool shaft 21 facing the slider 33. The spool shaft 21 is fastened to the slider 33 by a screw 46 with the locking plane 42 abutting against the mounting plane 41. The lower edge of the locking plane 42 abuts on the support plane 49 and is supported by the support plane 49 from below.

  As shown in FIG. 6, the slider 33 and the oscillation drive gear 63 are adjacent to each other in the width direction of the reel body 2. A guide groove 64 is formed on the surface of the slider 33 that faces the oscillation drive gear 63. The guide groove 64 extends in the vertical direction while being bent, for example (see FIG. 5), and a convex portion 63a of the oscillating drive gear 63 is slidably fitted inside the guide groove 64.

  When the handle 26 is operated in the direction of winding the fishing line, the rotation of the driving gear 23 is transmitted to the oscillating driving gear 63 via the relay gear 62, and the oscillating driving gear 63 rotates. By the rotation of the oscillating drive gear 63, the convex portion 63 a revolves around a screw 65, and apparently the convex portion 63 a moves up and down along the guide groove 64.

  As a result, the rotational motion of the oscillating drive gear 63 is converted into a reciprocating linear motion by the fitting between the convex portion 63 a and the guide groove 64 and transmitted to the slider 33. Since the slider 33 is fixed to the rear end portion 21 a of the spool shaft 21, the spool shaft 21 reciprocates in the front-rear direction of the reel body 2 together with the spool 4.

  According to the spinning reel 61 for fishing having such a configuration, for the same reason as in the first embodiment, the smoothness of the reciprocating motion of the spool shaft 21 is improved, and the reel body 2 is reduced in size and weight. Can be planned.

  Further, if the slider 33 is provided with the support plane 49, the position and posture of the spool shaft 21 are defined from two directions, so that the accuracy of the position and posture of the spool shaft 21 is further increased. Further, the slider 33 can be more reliably prevented from rotating with respect to the spool shaft 21.

  The fishing spinning reels 1 and 61 according to the first and second embodiments have been described above, but the present invention is not limited to these. The components according to the first and second embodiments can be applied in appropriate combination. The present invention is not limited to the first and second embodiments described above, and can be variously modified without departing from the spirit of the invention.

  For example, the slider 33 according to the second embodiment may have another support plane 57 facing the spool shaft 21 from above as shown in FIG. In the first and second embodiments, the guide portions 52 and 53 are not necessarily provided, and may be omitted as appropriate. However, the presence of the guide portions 52 and 53 can further suppress backlash of the slider 33 along the circumferential direction of the spool shaft 21.

  The fastening means between the slider 33 and the spool shaft 21 is not limited to the screw 46. For example, a through hole that opens toward the slider 33 is formed in the spool shaft 21, and a protrusion that is inserted through the through hole is formed in the slider 33. Then, the slider 33 and the spool shaft 21 may be fastened by crushing the tip of the protrusion that is inserted through the through hole and protrudes to the back side of the spool shaft 21 or by engaging a nut with the tip of the protrusion. .
