It is rotatably supported between the take-off position and the fishing line discharge position. One base end of the bail 2b is attached to a fishing line guide 2d provided integrally with the bail support member 2c.
[0012]
A handle shaft 5a is rotatably supported in the reel body 1, and a handle 5 is attached to the protruding end portion. Further, a power transmission mechanism 7 is engaged with the handle shaft 5a. The power transmission mechanism is attached to the handle shaft 5a and meshes with the drive gear 8 formed with internal teeth. In addition, a pinion 9 extending in a direction orthogonal to the handle shaft 5a and having a hollow portion extending in the axial direction therein is provided.
[0013]
The pinion 9 is rotatably supported in the reel body via a bearing, and the hollow portion extends in a direction orthogonal to the handle shaft 5a, and the spool shaft 3a is mounted with the spool 3 on the tip side. Is inserted so as to be movable in the axial direction. The pinion 9 extends toward the spool, and the rotor 2 is attached to the tip of the pinion 9 so that the rotor can rotate when the pinion 9 is driven to rotate.
[0014]
The pinion 9 is engaged with a fishing line parallel winding device 10 for reciprocating the spool 3 (spool shaft 3a) when the pinion 9 is rotationally driven in accordance with the rotation operation of the handle 5. .
[0015]
The parallel fishing line winding device 10 is rotatably supported in the reel body via a bearing, and has a rotating shaft (traverse cam shaft) 12 extending in parallel with the spool shaft 3a, and a screw at the base end of the spool shaft 3a. The traverse cam shaft 12 is provided with a cam groove 12a having a shape as described later. The slider 15 holds an engaging member 17 that engages with the cam groove 12a. When the traverse cam shaft 12 is driven to rotate, the engaging member 17 engages with the cam groove 12a that rotates together with the traverse cam shaft 12. Is guided in the cam groove and reciprocates back and forth.
[0016]
The cam groove 12a has such a shape that the engagement member 17 engaged therewith moves forward and backward in the front-rear direction, so that the forward movement groove and the backward movement groove do not cross each other. It is continuously formed along the outer peripheral surface of the traverse cam shaft, and when the engaging member 17 makes one stroke in the cam groove 12a as the traverse cam shaft 12 rotates, the engaging member 17, that is, the slider 15 makes one reciprocation. It comes to be moved.
[0017]
In this case, the cam groove 12a is formed in a shape having no intersecting portion, and is continuously formed along the outer peripheral surface of the traverse cam shaft. It is difficult. For this reason, the traverse cam shaft 12 needs to have a lower rotational speed than the conventional configuration, and between the pinion 9 and the traverse cam shaft 12, the rotation of the pinion 9 is decelerated and transmitted to the traverse cam shaft 12. A speed reduction mechanism 20 is disposed.

The planetary mechanism is integrally formed with a sun gear 21 rotatably attached to the traverse cam shaft 12 and the sun gear. A gear 22 meshing with the pinion 9, an internal gear 23 fixed to the reel body 1, and a plurality of planetary gears 24 disposed between the sun gear 21 and the internal gear 23 and meshing with both. It has. The plurality of planetary gears 24 are rotatably supported by a carrier 25 fixed to the traverse cam shaft 12 so as to revolve around the sun gear 21 integrally. According to such a speed reduction mechanism, the rotation of the pinion 9 that rotates together with the rotation of the handle is decelerated by the planetary gear 24 via the gear 22 and the sun gear 21, and the reduced drive rotation is traversed via the carrier 25. It can be transmitted to the camshaft 12.
[0019]
Further, the engaging member 17 held by the slider 15 may be formed integrally with the slider 15 or may be configured to be attached to the slider as a separate body. In the present embodiment, as shown in FIGS. 4A and 4B, the slider 15 is integrally formed so as to protrude from the surface of the slider 15 so that substantially the whole enters the cam groove 12a. It is configured. In this case, as shown in the figure, a bearing (rolling bearing) 18 is preferably provided on the outer periphery of the engaging member 17, and by providing such a rolling bearing, the groove 12 a The sliding frictional resistance is reduced, and the engaging member 17 can move smoothly. In addition, such a bearing may be comprised with a sliding bearing, and the structure which does not arrange | position a bearing may be sufficient as it.
[0020]
With the above-described configuration, when the handle 7 is wound up, the rotor 2 is rotationally driven via the drive gear 8 and the pinion 9, and the spool 3 is rotationally driven on the traverse cam shaft 12 by the pinion 9 and the speed reduction mechanism 20. By doing so, it is reciprocated back and forth via the engaging member 17 that engages with the traverse cam groove 12a formed on the outer periphery thereof. As a result, the fishing line is evenly wound around the winding body 3a of the spool 3 via the fishing line guide 2d.
[0021]
The cam groove 12a described above has a shape in which no intersecting portion is formed when the engagement member 17 is moved forward and backward, so that the engagement guide state of the engagement member 17 is stable, and the slider Thus, it is possible to reliably prevent the occurrence of abnormal noise such as 15 malfunctions and noises, and a good reciprocating function is obtained.
[0022]
5A and 5B are diagrams showing a first modification of the above-described embodiment, wherein FIG. 5A is a diagram showing a configuration of a traverse cam shaft, and FIG. 5B is a diagram of FIG. It is.
As shown in this modification, the traverse cam shaft 12 is preferably formed with a large diameter (diameter: about 8 to 15 mm). By making the traverse cam shaft 12 have a large diameter, the groove shape in the folded back portion (region indicated by P) of the engaging member in the longitudinal direction is maintained while maintaining a sufficient longitudinal stroke of the slider 15. It becomes possible to make it into a shape, and this makes it possible to smoothly move the engagement member at the folded back part of the longitudinal movement.
[0023]
6 and 7 are diagrams showing a second modification of the above-described embodiment, FIG. 6 is a diagram showing a configuration of a fishing line parallel winding device, and FIG. 7 is an engagement held by a slider. It is a figure which shows the structure of a member.
In this modification, the engaging member 37 is formed separately from the slider 15 and is supported by the rolling bearing 38 so as to be rotatable with respect to the slider 15. The engaging member 37 includes a tip engaging portion 37a protruding from the surface of the slider, and the tip engaging portion 37a enters the cam groove 12a so that the slider 15 reciprocates back and forth. It has become.
[0024]
According to such a configuration, when the traverse cam shaft 12 is driven to rotate, the engaging member 37 is guided by the cam groove 12a and smoothly rotates through the rolling bearing 38 to move the slider 15 forward and backward. Reciprocate.
Thus, the configuration of the engagement member held by the slider can be appropriately modified.
[0025]
8 and 9 are diagrams showing a third modification of the above-described embodiment, FIG. 8 is a diagram showing a configuration of a fishing line parallel winding device, and FIG. 9 is taken along line CC in FIG. FIG.
This modification is a modification of the structure of the power transmission portion that transmits the rotational drive by the handle winding operation to the traverse cam shaft 12, and the power input to the traverse cam shaft 12 can be transmitted without using the pinion 9. It is configured to input directly from the handle shaft 5a.
[0026]
A worm gear 40 is formed on the handle shaft 5a to which the handle is mounted, and one end side of a driven shaft 41 that is rotatably supported with respect to the support portion 1b of the reel body 1 is supported on the worm gear 40. Is engaged with a driven gear 42 attached thereto. A driven gear 43 is attached to the other end side of the driven shaft 41, and the driven gear 43 meshes with the gear 22 of the planetary mechanism described above.
[0027]
According to such a configuration, as compared with a configuration in which power is transmitted via the drive gear 8 and the pinion 9 attached to the handle shaft 5a, the rotation of the handle shaft 5a is not accelerated once by the drive gear 8. Since the power is transmitted from the number, the input rotation speed to the planetary mechanism can be lowered, and the deceleration effect can be increased. That is, since deceleration is performed from the handle shaft 5a that is rotationally driven together with the winding operation of the handle via the worm gear 40 and the driven gear 42, it is possible to achieve greater deceleration.
[0028]
In this modification, the planetary mechanism further enhances the deceleration effect. However, since the gear ratio of the worm gear 40 and the driven gear 42 can sufficiently reduce the speed, the planetary mechanism is provided. Instead, the power may be directly transmitted from the driven gear 43 to the traverse cam shaft 12.
[0029]
As described above, the embodiment of the present invention has been described. However, the present invention is not limited as long as the cam groove shape formed on the traverse cam shaft is formed so as not to have an intersecting portion. The configuration of transmitting power to the shaft and the configuration of a speed reduction mechanism that reduces the amount of rotation can be modified as appropriate. Moreover, the above-described fishing line parallel winding device can also be applied to a dual-bearing reel.
[0030]
