DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel.

[0002]

2. Description of the Related Art A spinning reel is provided with an oscillating mechanism having a slider fixed to a rear portion of a spool shaft having a spool concentrically mounted at a leading end thereof. The fishing line is wound up evenly. During the winding of the fishing line associated with the rotation of the handle, rattling occurs in the rotation direction of the spool about the spool shaft, which causes abnormal noise during rotation of the handle and hinders the smooth and stable operation of the winding operation of the fishing line. Was.

[0003] The spool is frictionally fixedly connected to the spool shaft, and since the slider is fixed to the spool shaft, the sliding gap of the slider causes play. Therefore, Japanese Patent Publication No. Sho 61-6766 discloses that the lower end of the slider is slidably fitted to a guide rail formed on the reel body to prevent backlash. Further, a slider is fitted to a guide rod member attached to the front and rear of the reel body so as to be movable back and forth.
No. 66 is disclosed.

[0004]

However, by restricting the play in the rotation direction of the slider fixed to the spool shaft with a guide rail or a guide rod member, the rotation direction of the spool shaft (that is, the spool) is indirectly controlled. This is a configuration that suppresses play. That is, a slider is interposed between the backlash regulating member on the reel body side and the spool shaft, and an assembling portion for assembling the slider with the engaging portion for changing the original rotational motion into a linear motion or the regulating member. Due to the existence of a gap between the slider and the engaging portion or the regulating member, which arises from the viewpoint of accuracy, or the degree of connection between the slider and the spool shaft, play in the rotation direction of the spool shaft cannot be suppressed, This adversely affects the smooth sliding of the rotor. Therefore, in general, a smooth rotation cannot be sufficiently achieved due to abnormal noise generated during the operation of rotating the steering wheel or local wear of the sliding mechanism.

Accordingly, an object of the present invention is to provide a spinning reel that can smoothly move back and forth while preventing the play in the rotational direction of the spool due to the rotation of the handle, and can smoothly rotate the handle.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned object, the present invention provides a slider attached to a rear portion of a spool shaft having a spool attached to a tip portion, and a handle is rotated by an oscillating mechanism having the slider. A spinning reel that converts the movement into a back-and-forth movement and moves the spool back and forth, wherein an engagement portion held on a reel body is engaged with the spool shaft, and the spool shaft has a long groove along the axial direction. A ridge is formed, and the engaging portion is formed with a ridge engaging with the groove or a groove for receiving the ridge, and the spool shaft is prevented from rotating around the axis so as to be slidable along the axial direction. It is configured so that: Here, the groove includes a through-hole.

[0007]

Since the engagement portion held on the reel body and the spool shaft are directly slidably engaged without the interposition of a slider, the engagement accuracy can be increased and the play around the shaft center can be improved. In addition, since the engagement mechanism and the oscillating mechanism of the slider are separated from each other, the forward and backward movement of the spool due to the handle rotation operation is smooth, and the rotation play is prevented. Operation becomes smooth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a side view of a partially broken spinning reel according to the present invention, FIG. 2 is an enlarged view of a main part thereof, and FIG. 3 is a cross-sectional view taken along line CC of FIG. The spool 12 is frictionally coupled to a leading end of the spool shaft 10, and a slider 18 is fixed to a rear end of the spool shaft 10 by a screw member 28. Furthermore, a pinion gear 17 whose rotation is transmitted to the rotor 14 is fitted over the intermediate portion of the spool shaft 10 with a gap, and when the handle is rotated, the drive gear 16 rotates, and the pinion gear 17 Meshed with the drive gear 16,
As a result, the rotor 14 is rotated.

A traverse camshaft 20, which is spaced apart from the spool shaft 10 and rotates in conjunction with the drive gear 16, is supported on a reel body 22 by a bearing 21. The camshaft 20 has a cam groove 20A. Have been. The slider 18 has an engaging portion 18K protruding therefrom, and is engaged with the cam groove 20A of the cam shaft. Accordingly, the spool shaft 10 linearly moves back and forth with the slider 18 with the rotation of the handle. This mechanism is called an oscillating mechanism.

Therefore, the spool 12 connected to the spool shaft 10 moves back and forth in synchronization with the rotation of the rotor 14, so that the fishing line is evenly wound around the spool. As described above, the slider 18 essentially only linearly moves, but there is play in the rotation direction about the spool shaft 10. In order to prevent this play, the spool shaft 10 is formed with a groove 10M that is long in the axial direction and dug in the radial direction.
The distal end portion 26S of the screw member 26 having almost the same width as the width of the groove is engaged with the groove 10M. The screw member 26 is inserted from below the reel body 22 (the opposite side of the reel leg),
A portion near the head is screwed and held to the reel body 22, and the spool shaft 10 slides back and forth while the play in the rotational direction is directly prevented by the tip end portion 26S of the screw member held by the reel body 22. Moving. Therefore, the spool moves back and forth smoothly, and the rotation of the handle becomes smooth.

FIGS. 4 and 5 show a modification (second embodiment) of the first embodiment. The spool shaft 10 is formed with a groove 10M 'which extends over a predetermined range in the length direction and penetrates in the diameter direction.
