Description

[Detailed Description of the Invention] The present invention is a spinning reel, specifically, a spool having a body and a pair of front and rear flanges,
The present invention relates to a spinning reel including a spool shaft that rotatably supports the spool, a drag plate that applies a braking force to the rotation of the spool, and a drag knob that adjusts the braking force of the drag plate.

Conventionally, a spool rotatably supported by a spool shaft has been made rotatable by fitting a fitting hole formed in the center of the body onto the outer periphery of the spool shaft. A spool receiver provided on the spool shaft prevents the spool from moving backward with respect to the spool shaft, and a drag knob is screwed onto the front end of the spool shaft, and a space between the drag knob and the front flange of the spool is provided. The drag plate is interposed in the spool, and when the drag knob is rotated, the drag plate slides and comes into pressure contact with the front flange, thereby applying a braking force to the rotation of the spool.

By the way, the fitting hole of the spool is long in the axial direction and is subjected to sliding friction against the outer circumference of the spool shaft. In addition, the fishing line wound around the body of the spool is pulled out in a tangential direction from the outer periphery of the wound part, and then hooked onto an arm roller of a rotating frame that can only rotate with respect to the spool shaft that moves back and forth in the front and back direction. The fishing line is fed out from this arm roller to the front of the spool, and when winding up this fed fishing line, the rotating frame is rotated, and the bail arm having the arm roller of this rotating frame is used to unwind the fishing line. The fishing line is wound around the outer periphery of the body of the spool, and the spool is reciprocated in the front and back direction by the reciprocating mechanism so that the fishing line is wound parallel to the center of the spool by the bail arm. It is now possible to do so.

Therefore, when the rotary frame is rotated and the bail arm of the rotary frame is used to wind the fishing line around the body of the spool to catch a fish, the fishing line guided to the spool from the arm roller is guided around the outer periphery of the line wrapping section. At the same time, the position at which the fishing line is wound is displaced in the front-back direction due to the reciprocating movement of the spool in the front-back direction by the reciprocating mechanism, so the spool is subjected to a tangential tensile load when winding the fishing line. However, it acts while changing its position in the winding direction and changing its direction in the axial direction centering on the arm roller. As a result, the spool, which is rotatably supported on the spool shaft, is tilted with respect to the spool shaft, causing an uneven contact phenomenon in which only the axial end of the fitting hole in the spool and only a portion of the radial direction abuts. This uneven contact phenomenon causes a tensile load to act on the spool.

Therefore, as the one-sided contact position of the fitting hole is displaced in the circumferential direction, the direction of inclination of the spool also changes, and when a tensile load is applied to the spool while the spool is inclined with respect to the spool axis, the spool The rotational frictional resistance against the spool shaft increases, and this rotational frictional resistance greatly affects the braking force of the drag plate, and these rotational frictional resistance and braking force counteract the tensile load of the fishing line. Since the contact surface of the spool with the drag plate is also inclined with respect to the drag plate, the state of pressure contact between the drag plate and the spool will also vary, resulting in strong pressure contact in some areas, causing uneven rotation of the spool. This makes it impossible to smoothly rotate the spool with a braking force commensurate with the braking force provided by the drag plate. As a result, the fishing line may break or the fish may escape.

The present invention was devised in view of the above points, and the purpose is to minimize the inclination of the spool with respect to the spool axis, and to reduce the rotational frictional resistance of the spool with respect to the spool axis.
The object is to enable smooth rotation with a braking force commensurate with the braking force provided by the drag plate.

Therefore, the present invention provides a spool having a body and a pair of front and rear flanges, a spool shaft that rotatably supports the spool, a drag plate that applies a braking force to the rotation of the spool, and a drag plate that provides a braking force to the rotation of the spool. In a spinning reel equipped with a drag knob for adjusting braking force, a rotational support portion extending in the length direction of the body is provided at a portion of the spool shaft corresponding to the body, and the support portion and the body are connected to each other. The spool is comprised of an outer ring that fits into the body, an inner ring that is attached to the support part, and a rolling element that is interposed between the outer ring and the inner ring, and suppresses inclination of the spool with respect to the spool axis. A bearing was inserted.

The spool 6 includes a body portion 61 having a fitting hole at the center and a pair of front and rear flanges 63 and 62 extending radially outward from both front and rear ends of the body portion 61.

Further, the drag mechanism 7 is configured such that the relationship between the amount of operation of the drag knob 71 and the braking force applied to the spool 6 has a linear characteristic as shown in FIG.

That is, the drag plate 72 has a thin flexible portion 73 formed in the middle portion in the radial direction.
A receiving surface 74, 75 for the drag knob 71 is formed on the outer circumferential side and the inner circumferential side of the front surface, and a front flange 6 is formed on the outer circumferential side of the flexible portion 73 on the rear surface.
3 to form a friction surface 76 for the friction surface on the outer surface. The drag knob 71 also includes the receiving surfaces 74 on the outer circumferential side and the inner circumferential side of the drag plate 72,
Pressing surfaces 77 and 78 are formed at the portion corresponding to 75, and the distance between the outer peripheral side receiving surface 74 and the pressing surface 77 is set later than the distance between the inner peripheral side receiving surface 75 and the pressing surface 78. It is made larger by a certain value a.

The friction surface 76 of the drag plate 72 and the outer surface of the front flange 63 are formed so that the distance between them in the spool shaft 4 direction increases from the outside to the inside in the radial direction, as shown in FIG. The outer pressing surface 77 of the drag knob 71 and the receiving surface 74 of the drag plate 72 are formed such that the axial distance between them becomes wider from the inside to the outside in the radial direction, as shown in FIG. Then, the drag plate 7 is pressed by the pressing surface 78 of the drag knob 71.

While gradually increasing the pressing force applied between the friction surfaces of the spool 6 and the spool 6, as shown in FIG. It is made to increase in shape.

The present invention is constructed as described above, and after the fishing line wound around the body 61 of the spool 6 is pulled out in the tangential direction from the outer periphery of the wound portion, the fishing line is attached to the spool shaft 4 which reciprocates in the front and back direction. The fishing line is hooked onto an arm roller of a rotary frame 31 that can only be rotated, and is let out from this arm roller to the front of the spool 6. Also, when winding up this let-out fishing line, the rotary frame 31 is rotated, The baited fishing line is wound around the outer periphery of the body 61 of the spool 6 by the bail arm having the arm roller of the rotating frame 31, and the spool 6 is reciprocated in the front and rear directions by a reciprocating mechanism. The fishing line is wound by the bail arm parallel to the center of the spool 6. For this reason,
When the rotating frame 31 is rotated and the fishing line is wound around the body 61 of the spool 6 by the bail arm of the rotating frame 31 to catch a fish, the fishing line guided from the arm roller to the spool 6 is guided to the line winding section. The fishing line is wound around the outer periphery, and the position at which the fishing line is wound is displaced in the front-back direction due to the reciprocating movement of the spool in the front-back direction by the reciprocating mechanism. As the tensile load changes position in the winding direction,
The spool 6 acts while changing its direction in the axial direction centering on the arm roller.
Since it is supported by the bearing 9, in detail, the outer ring 93 of the bearing 9 is fitted into the fitting hole of the body part 61, and the inner ring 92 is attached to the rotation support part 8, so that the spool 6 can be rotated. Since the rotational frictional resistance of the spool support part can be made small, the rotational performance of the spool 6 can be made very good, and the rotational frictional resistance of the said supporting part does not affect the braking force of the drag plate 72. can be greatly reduced. Moreover, the radial inclination of the spool 6 with respect to the spool shaft 4 can be suppressed to a minimum, and the drag plate 72
It is possible to reduce fluctuations in the pressure contact state of the spool 6 to the front flange 63, and to stably maintain the braking force by the drag plate 72, which eliminates uneven rotation of the spool 6.
This allows for smooth rotation with a braking force commensurate with the braking force. As a result, the fishing line can be prevented from being cut.

Furthermore, since the relationship between the amount of drag operation by the drag mechanism 7 and the braking force applied to the spool 6 is linear, the spool 6 is caused to tilt slightly in the radial direction with respect to the spool axis due to the tensile load of the fishing line. Therefore, the amount of variation in the braking force can be made extremely small, and the rotation of the spool can be performed even more smoothly.

In the above explanation, one needle bearing is used as the bearing 9, but two bearings (not shown) are installed between the rotation support part 8 and the body part 61 of the spool 6. It may also be installed at positions on both sides separated by an interval that can prevent the spool from falling in the radial direction with respect to the spool shaft 4.

As described above, the present invention includes a rotating support portion extending in the length direction of the body portion of the spool shaft at a portion corresponding to the body portion of the spool, and a rotating support portion extending in the length direction of the body portion, and a rotation support portion extending in the length direction of the body portion. The spool is made up of an outer ring that fits into the support part, an inner ring that is attached to the support part, and rolling elements that are interposed between the outer ring and the inner ring, and a bearing that suppresses the inclination of the spool with respect to the spool axis. The rotational frictional resistance of the support part can be reduced, and the spool can be rotated very well.
The influence of the rotational frictional resistance of the spool support portion on the braking force exerted by the drag plate can be greatly reduced. Moreover, by supporting the body of the spool on the rotation support part via the bearing, the inclination of the spool with respect to the spool axis can be minimized, and fluctuations in the state of pressure contact of the drag plate to the spool can be minimized. Since the braking force by the drag plate can be maintained stably, uneven rotation of the spool can be eliminated, and the spool can be rotated smoothly with a braking force commensurate with the braking force by the drag plate. Therefore, it is possible to prevent the fishing line from being cut or the fish from being caught.
