DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing spinning reel having an improved oscillating mechanism for a slider for moving a spool back and forth.

[0002]

2. Description of the Related Art Conventionally, a slider of an oscillating mechanism provided in a reel body for converting the rotation of a handle into a longitudinal movement has a rear portion of a spool shaft having a spool at a tip end. In order to allow the slider to move back and forth while being mounted, a gear is fitted and fixed to the shaft of the drive gear and a pin is fixed to the gear meshing with the gear as disclosed in Japanese Patent Publication No. 50-21390. The slider is moved back and forth by moving the slider back and forth, or as shown in Japanese Utility Model Publication No. 55-39976, the connecting plate connected to the slider is actuated by the cam provided on the side of the drive gear. A method of moving a slider or a slider fitted to a traverse cam shaft in a longitudinal direction is known, as disclosed in Japanese Utility Model Publication No. 61-6676 and Japanese Utility Model Laid-Open Publication No. 4-38266. When the fishing line is wound around the spool while the slider is moved back and forth as described above, the slide is performed under a condition where a load is applied to the fishing line, so that rattling occurs in the rotation direction of the spool shaft. In addition, the durability is reduced due to the occurrence of the play, and the oscillating function is reduced due to the deformation of the engaging portion.

In order to reduce the play in the rotation direction of the spool shaft and to prevent a decrease in durability caused by the play and a decrease in the oscillating function due to deformation of the engaging portion, etc.
In Japanese Utility Model Publication No. 55-39976, a pin is provided on a slider and inserted into a groove of a reel body. In Japanese Utility Model Publication No. 61-6676, the lower end of the slider is slidably fitted so as to straddle a guide rail formed on the bottom surface of the casing in the reel body. Further, in Japanese Utility Model Laid-Open Publication No. 4-38266, a guide rod attached to a reel body is passed through a slider. However, in the above configuration, the pin and the groove, the guide rail or the guide rod, and the slider are of the sliding type, so that the frictional resistance is large and the fishing line is slid under the condition that the load is applied to the fishing line. Was bad. Further, the parallelism of the groove, the guide rail and the guide rod in the y direction and the z direction in the lateral direction is required for the spool axis.

If the degree of parallelism is poor, the fitting accuracy of the pin and the groove, the guide rail or the guide rod and the slider to which the rear part of the spool shaft is attached is deteriorated, the frictional resistance is increased, and the longitudinal movement is improved. In addition to having a negative effect on the oscillating function, a smooth oscillating function cannot be obtained.
If the fitting accuracy for maintaining the parallelism with the spool shaft is made somewhat rough in consideration of the case where a dimensional error occurs in the parts, the play in the rotational direction of the spool shaft, that is, the slider, is reduced. And the problem that the oscillating function deteriorates occurs as described above. Further, when the frictional resistance is increased, the winding operation of the fishing line becomes heavy, the sliding portion is easily worn, the durability is poor, and a stable oscillating function cannot be obtained for a long time.

[0005]

The problem to be solved is that the slider is supported and guided in the state of sliding in contact with the reel body when moving in the front-rear direction.
Since the sliding is performed under a condition where a load is applied to the fishing line, the winding efficiency is poor, the sliding portion is easily worn, the durability is poor, and a stable oscillating function cannot be obtained for a long time. Spoon
A high degree of parallelism of the slider is required with respect to the axis, but it is difficult. If the degree of parallelism is poor, the frictional resistance increases, the winding operation of the fishing line becomes heavy, and a more stable oscillating function cannot be obtained. . If the fitting accuracy for maintaining the parallelism with the spool shaft is made somewhat rough, the play in the rotation direction of the slider becomes large, and the oscillating function is reduced.

SUMMARY OF THE INVENTION In view of the above drawbacks, the object of the present invention is to reduce the influence of the parallelism to the spool axis by reducing the sliding friction of the sliding system to the rolling friction and to achieve a light and smooth winding operation. An object of the present invention is to provide a spinning reel for fishing.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, there is provided an oscillating device provided in a reel body for converting the rotation of a handle into a back and forth motion. In a spinning reel for fishing, a rear part of a spool shaft having a spool at a tip end is attached to a slider of a mechanism, and the spool shaft is moved back and forth. The invention is characterized in that a rolling member is interposed between the sliding member and the sliding body, and the slider is guided to roll in the front-rear direction. According to a second aspect of the invention, a longitudinal groove is provided in the reel body, and the rolling member provided on the slider is slidably contacted with a wall surface in the groove to move the slider in the longitudinal direction. The gist is that rolling guidance is provided.

To allow the slider to move back and forth, and a rolling member is provided between the outer circumference of the guide rod and the inner circumference of the recess to guide the slider in the front-rear direction. is there. According to a fourth aspect of the present invention, a convex ridge in the front-rear direction is provided in the reel body, and the rolling member provided on the slider is slid on the wall surface of the convex levee to move the slider forward and backward. The gist of the present invention is that the rolling direction is guided. According to a fifth aspect of the present invention, the traversing cam shaft provided with the traversing cam groove for rotating the oscillator mechanism of the slider in conjunction with the handle is provided with an engaging pin for engaging the traversing cam groove. The gist of the present invention is that a slider is fitted to the slider, and the slider is guided to roll in the front-rear direction.

[0008]

According to the fishing spinning reel according to the first aspect, the slider 5 is rolled in the front-rear direction by the rolling member interposed between the slider 5 and the reel body 1. Is done. According to the spinning reel for fishing according to claim 2,
A slider 5 is provided on the wall surface in the longitudinal groove provided in the reel body 1.

According to the spinning reel for fishing according to the fourth aspect, the rolling member provided on the slider is slidably contacted with the wall surface of the convex bank in the front-rear direction provided on the reel body 1. According to the fishing spinning reel of the fifth aspect, the oscillating mechanism of the slider engages with the traverse scum groove on the traverse scum shaft provided with the traverse scum groove which rotates in conjunction with the handle. The slider provided with the engagement pin is fitted and slid in the front-rear direction. When the slider is brought into sliding contact as described above, the sliding contact of the slider 5 becomes rolling friction, and the parallelism of the slider 5 with respect to the spool axis in the y direction is determined by the fact that the rolling member is releasable. Since it is not constrained in the vertical direction (y direction) of the main body 1, the frictional resistance does not increase due to the parallelism problem. Further, even if there is an error in the parallelism in the z direction, even if there is an error in the parallelism, it is absorbed by the minute rotation of the rolling member and the self-aligning action, and the frictional resistance does not increase.
