  Thus, the traverse cam shaft 21 is disposed between the first guide shaft 38a and the second guide shaft 38b in the vertical direction.

  The engaging member 25 is, for example, a rod-shaped metal member. As shown in FIGS. 4 and 6, the engagement member 25 is disposed in the through hole 24f of the engagement member mounting portion 24b. The engaging member 25 has a shaft portion 25a and an engaging portion 25b. The shaft portion 25a is formed integrally with the engaging portion 25b. The engaging portion 25b is provided at the distal end portion of the shaft portion 25a and can be engaged with the spiral groove 21a.

  Here, FIG. 11A corresponding to the present embodiment and FIG. 11B corresponding to the prior art (FIG. 6 of JP 2010-172272 A) are compared to describe the configuration of the present embodiment. FIG. 11A is a schematic diagram for comparison with FIG. 11B. The reference numerals in FIG. 11B are different from those in FIG. 6 of the prior art, but the configuration is the same.

  As described in the section of the prior art, in the conventional example shown in FIG. 11B, the distal end portion 425a of the engaging claw 425 is disposed inside the spiral groove 421a. In addition, in the direction away from the bottom of the spiral groove 421a, the length T2 of both end portions 428 at the distal end portion 425a of the engagement claw 425 is shorter than the depth F2 of the spiral groove 421a. That is, the entire front end portion 425a of the engaging claw 425 functions as a sliding portion, and slides with the spiral groove 421a. On the other hand, in the present embodiment shown in FIG. 11A, the length of both end portions of the distal end portion 125a of the engaging claw 125, for example, the protruding length T1 of the protruding portion 128 is longer than the depth F1 of the spiral groove 21a. Therefore, in a state where the non-sliding portion 140 of the projecting portion 128 is disposed outside the spiral groove 21a, the sliding portion 130 at the distal end portion 125a of the engagement claw 125 slides with the spiral groove 21a.

  In the prior art, when viewed from the direction along the traverse cam shaft 21, the tip end portion 425a (sliding portion) of the engaging claw 425 overlaps the spiral groove 21a. On the other hand, in this embodiment, when viewed from the direction along the traverse cam shaft 21, the sliding portion 130 is overlapped with the spiral groove 21a, and the non-sliding portion 140 of the protruding portion 128 is the spiral groove. It is arranged outside 21a.

  In the prior art, the width W <b> 2 at both ends of the engaging claw 425 is smaller than the diameter R of the traverse cam shaft 421. On the other hand, in the present embodiment, the width W 1 of the engagement claw 125 is larger than the diameter R of the traverse cam shaft 21.

Explaining this embodiment in more detail, as shown in FIG. 7, the engaging portion 25 b includes a disc portion 25 e and an engaging claw 125. The disc part 25e is formed larger in diameter than the shaft part 25a. The disc part 25e is fitted in the through hole 24f. The first surface 25g of the disc portion 25e on the traverse cam shaft 21 side comes into contact with a regulation protrusion (not shown) formed in the through hole 24f. Thereby, the movement of the engaging member 25 to the traverse cam shaft 21 side is regulated. That is, when the engaging portion 25b is positioned in the axial direction by the restricting projection, the interval between the engaging portion 25b and the traverse cam shaft 21 is kept constant.

  As shown in FIGS. 7 and 8, the engaging claw 125 protrudes in a plate shape from the disc portion 25e toward the traverse cam shaft 21, and engages with the spiral groove 21a. When the traverse cam shaft 21 rotates, the engaging claw 125 is guided in the spiral groove 21a, and the slider 22 moves in the front-rear direction along the traverse cam shaft 21. For example, when the slider 22 moves along the traverse cam shaft 21, either one of both end portions of the engagement claw 125 is arranged in a direction in which the engagement member 25 advances along the spiral groove 21a. Hereinafter, the end portion of the engaging claw 125 disposed in the traveling direction of the engaging member 25 is defined as “front end”. In addition, an end portion of the engaging claw 125 disposed in the direction opposite to the moving direction of the engaging member 25 is defined as “rear end”.

  As shown in FIG. 7, both side surfaces of the engaging claw 125 are in contact with an arcuate portion of a restriction projection (not shown). Thereby, the rotation range of the engaging member 25 is regulated. Further, both end portions of the engaging claw 125 protrude from the spiral groove 21a in a direction away from the bottom of the spiral groove 21a. The engaging claw 125 has a proximal end portion 124 and a distal end portion 125a. The proximal end portion 124 is a portion between the disc portion 25e and the distal end portion 125a. The base end portion 124 is formed integrally with the disc portion 25e. The base end portion 124 is substantially formed in a rectangular plate shape. The distal end portion 125a is a portion that engages with the spiral groove 21a. The distal end portion 125a is formed in a substantially arc shape so as to follow the bottom portion of the spiral groove 21a. The distal end portion 125 a is formed to be tapered from both side surfaces of the proximal end portion 124.

  The distal end portion 125 a of the engaging claw 125 is formed wider than the proximal end portion 124 of the engaging claw 125. Both end portions of the distal end portion 125a are portions corresponding to both end portions of the engaging claw 125, and partially protrude from the spiral groove 21a in a direction away from the bottom portion of the spiral groove 21a. Specifically, the distal end portion 125 a of the engaging claw 125 has a distal end central portion 127 and a pair of projecting portions 128. The front center portion 127 is a portion extending from the base end portion 124 toward the traverse cam shaft 21. Each of the pair of projecting portions 128 is a portion extending outward from both sides of the distal end central portion 127. The protruding portion 128 is formed integrally with the distal end central portion 127 so that at least a part of the protruding portion 128 protrudes from the spiral groove 21a in a direction away from the bottom of the spiral groove 21a.

  One of the pair of protrusions 128 corresponds to the above-described front end, and the other of the pair of protrusions 128 corresponds to the above-described rear end. That is, the protrusion 128 on the front end side (an example of the front end of the engaging claw) is an end disposed in the moving direction of the slider 22. The rear end side protruding portion 128 (an example of the rear end portion of the engaging claw) is an end portion disposed on the side opposite to the moving direction of the slider 22. In FIG. 7, for example, the left protrusion 128 is a front end protrusion 128a, and the right protrusion 128 is a rear end protrusion 128b.

  As shown in FIGS. 7 and 8, a part of the front end side protruding portion 128a and a part of the rear end side protruding portion 128b protrude from the spiral groove 21a in a direction away from the bottom of the spiral groove 21a. Yes. In other words, the protruding portion 128a on the front end side and the protruding portion 128b on the rear end side are formed so as to be longer than the depth F1 of the helical groove 21a in the direction away from the bottom of the helical groove 21a. More specifically, as shown in FIG. 7, the protruding length T1 of the front end side protruding portion 128a and the rear end side protruding portion 128b is the direction away from the bottom of the spiral groove 21a and the axis of the shaft portion 25a. It is formed so as to be longer than the depth F1 of the spiral groove 21a in the direction orthogonal to the core. Further, as shown in FIG. 6, the front end side protruding portion 128 a is set such that the width W1 between the front end side protruding portion 128 a and the rear end side protruding portion 128 b is larger than the diameter R of the traverse cam shaft 21. And the rear end side protruding portion 128b are provided.

  Here, the protrusion length T1 of the protrusion 128b and the depth F1 of the spiral groove 21a are defined in a direction orthogonal to the axis of the shaft 25a, but the direction away from the bottom of the spiral groove 21a. If so, the direction defining the protrusion length T1 of the protrusion 128b and the depth F1 of the spiral groove 21a may be another direction.

  Further, as shown in FIG. 7, a sliding portion 130 slidable in the spiral groove 21 a and a spiral groove 21 a at the distal end portion 125 a (the distal end central portion 127 and the protruding portion 128) of the engagement claw 125. A non-sliding portion 140 provided on the outside is provided.

  The sliding part 130 has an arc-shaped side surface 227a (only one side surface is shown in FIG. 7) and an end surface 227b. A side surface 227a of the sliding portion 130 is a surface facing the wall portion of the spiral groove 21a. An end surface 227b of the sliding portion 130 is a surface facing the bottom of the spiral groove 21a. Further, when viewed from the direction along the traverse cam shaft 21, the sliding portion 130 overlaps the spiral groove 21a. In FIG. 7, a portion corresponding to the sliding portion 130 is indicated by a broken line.

  The thickness of at least a part of both ends of the engaging claw 125, for example, the thickness of at least a part of the sliding part 130 at both ends of the tip 125a is set at the center of the tip center 127 in the direction along the spiral groove 21a. Greater than thickness. Further, the thickest portion 130a (see FIG. 7) of the sliding portion 130 is a portion facing the corner portion 21b on the opening side of the spiral groove 21a. The thickest portion 130 a of the sliding portion 130 is a part of a curved surface that forms the side surface of the distal end portion 125 a of the engaging claw 125. In FIG. 7, the thickest portion 130a of the sliding portion 130 is indicated by a black circle on the broken line. However, the thickest portion 130a of the sliding portion 130 does not necessarily have to be a point, and may be within a predetermined range. Good.

  Further, when the sliding portion 130 passes through a portion where the spiral groove 21a intersects, the thickest portion 130a of the sliding portion 130 can contact the corner portion 21b on the opening side of the spiral groove 21a. As described above, the thickness of the thickest portion 130a is set. For example, when the sliding portion 130 passes through a portion where the spiral groove 21a intersects, as shown in FIGS. 7 and 9, the thickest portion 130a of the sliding portion 130 is located on the opening side of the spiral groove 21a.

<Operation of the oscillating mechanism>
In the spinning reel 100 described above, when the handle 1 is rotated, the drive shaft 10 rotates and the pinion gear 12 that meshes with the drive gear 11 rotates. When the pinion gear 12 rotates, the rotor 3 rotates, the intermediate gear 23 rotates through the speed reduction mechanism 52, and the traverse cam shaft 21 rotates. When the traverse cam shaft 21 rotates, the slider 22 reciprocates in the front-rear direction along the traverse cam shaft 21. As the slider 22 reciprocates, the spool 4 moves back and forth.

  Here, the engagement relationship between the engagement claw 125 and the spiral groove 21a when the slider 22 moves along the spiral groove 21a of the traverse cam shaft 21 will be described. As described above, when the traverse cam shaft 21 rotates, the engaging portion 25b of the engaging member 25 attached to the slider body 24 is guided to the spiral groove 21a in a state of being engaged with the spiral groove 21a. . For example, the engaging claw 125 moves back and forth by the action of the spiral groove 21a while rotating around the shaft core of the shaft portion 25a while being engaged with the spiral groove 21a. Thus, when the engaging claw 125 is guided to the spiral groove 21a, the sliding part 130 at the tip end portion 125a of the engaging claw 125 slides along the spiral groove 21a.

  Specifically, as shown in FIG. 8, when the engaging claw 125 moves along the spiral groove 21 a, the sliding portion 130 of the distal end portion 125 a of the engaging claw 125 is formed on the wall portion of the spiral groove 21 a and Slide along the bottom. As described above, the sliding portion 130 includes the side surface 227a facing the wall portion of the spiral groove 21a and the end surface 227b facing the bottom portion of the spiral groove 21a. For this reason, the sliding part 130 always contacts the spiral groove 21a and slides along the spiral groove 21a. In particular, since the thickness of the sliding portion 130 on the protruding portion 128 side is larger than the thickness of the central portion of the distal end central portion 127, the play between the sliding portion 130 on the protruding portion 128 side and the spiral groove 21a becomes the protruding portion. In a state of being suppressed by the sliding portion 130 on the 128 side, the sliding portion 130 of the distal end central portion 127 and the sliding portion 130 of the protruding portion 128 slide along the spiral groove 21a.

  In addition, as shown in FIG. 9, when the engaging claw 125 passes near the intersection of the spiral grooves 21a, until the engagement claw 125 reaches the intersection of the spiral grooves 21a, the sliding claw 130 reaches the maximum. The thick part 130a (the thickest part on one side) contacts the corner 21b (the corner on the right side of the center in FIG. 9) on the opening side of the spiral groove 21a. In this case, the sliding portion 130 on the side where the thickest portion 130a abuts on the corner portion 21b is a wall portion on which the thickest portion 130a slides (the wall portion on the right side of the center in FIG. 9, one wall portion). Slide along. In this case, the sliding portion 130 on the opposite side slides along the other wall portion of the spiral groove 21a (the wall portion on the left side of the center in FIG. 9; the wall portion facing the one wall portion). Move.

  On the other hand, when the engaging claw 125 passes through the intersection of the spiral grooves 21a, the thickest portion 130a of the sliding portion 130 (the thickest portion on one side opposite to the above) It abuts on the corner 21b on the opening side (the lower left corner in the center of FIG. 9). In this state, the sliding portion 130 on the side where the thickest portion 130a is in contact with the corner portion 21b is slid along one wall portion (the lower left wall portion in FIG. 9) of the spiral groove 21a. Move. In this case, the sliding portion 130 on the opposite side slides along the other wall portion of the spiral groove 21a (the wall portion on the right side of the center in FIG. 9).

  Furthermore, as shown in FIG. 10, when the engaging claw 125 passes through the end portion of the traverse cam shaft 21, the concave portion 127 a on one side of the front end central portion 127 of the engaging claw 125 is located on the central portion side of the traverse cam shaft 21. Slide along the wall. The sliding portion 130 on the concave portion 127 a side also slides along the wall portion on the central portion side of the traverse cam shaft 21. On the other hand, the thickest part 130a in the sliding part 130 on the side opposite to the concave part 127a contacts the corner part 21b on the opening side of the spiral groove 21a. Further, the sliding portion 130 on the side where the thickest portion 130a abuts on the corner portion 21b slides along the wall portion (left wall portion in FIG. 10) of the spiral groove 21a. As described above, even when the engaging claw 125 passes through the end portion of the traverse cam shaft 21, the sliding portion 130 is moved along the spiral groove 21a by the surface contact between the sliding portion 130 and the spiral groove 21a. Moving.

  Thus, in the present oscillating mechanism 6, when the slider 22 reciprocates along the traverse cam shaft 21, the sliding portion 130 of the engaging claw 125 always makes surface contact with the spiral groove 21a, and the spiral groove Move along 21a. In detail, the non-sliding portion 140 of the protruding portion 128 of the engaging claw 125, for example, the edge portion 140a of the protruding portion 128 is always arranged outside the spiral groove 21a, and the sliding of the engaging claw 125 is performed. The part 130 moves along the spiral groove 21a while being in surface contact with the spiral groove 21a.
