Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool support structure for a spinning reel having a front drag mechanism.

[0002]

2. Description of the Related Art Conventionally, a structure shown in FIG. 5 is generally known as a spool supporting structure in a spinning reel having a front drag mechanism. The structure is such that a recess 103 is formed in the front surface of a spool 102 that is rotatably and detachably attached to a spool shaft 101.
A multi-plate drag washer 104 is housed in 03, and the drag washer 104 is retained by a clip ring 105 attached to the peripheral surface of the recess 103. Further, a drag knob 106 is screwed onto the tip of the spool shaft 101, and by rotating the drag knob 106, the drag washer 104 is pressed to change the drag force, or the spool 102 is detached and the spool 102 is detached. Has become.

By the way, since the drag mechanism exerts a drag force by friction of the drag washer, the drag washer wears during use and the drag force stops working. Therefore, it is possible to replace a worn drag washer. When replacing the drag washer in the above conventional spinning reel, remove the drag knob from the spool shaft,
The clip washer that holds the drag washer stored on the spool is removed, and the drag washer is replaced. However, the work of removing the clip ring is very troublesome because it must be done carefully using a special tool so as not to lose or break the clip ring. Further, when the spool is replaced, the spool cannot be replaced unless the drag knob is removed, so there is a risk that the drag knob may be accidentally lost when performing the replacement work on a rocky place or on a ship.

The present applicant has developed a spinning reel shown in FIG. 6 in order to solve the above drawbacks. In this structure, a cylindrical fixed drag body 202 is fixed to a spool shaft 201 that moves back and forth by the rotation of a handle, and a cylindrical rotary drag body 203 is freely rotatable and axially slidable on the fixed drag body 202. Mounted on the resistance plate 204 facing the ends of the drag bodies 202, 203.
205 is integrally provided, a drag washer 206 is inserted between the resistance plates 204, 205, and a cylindrical drag knob 207 is screwed onto the tip of the spool shaft 201 to rotate with the drag knob 207. A spring 208 is elastically mounted between the ends of the drag body 203, and a spool 209 having a through hole formed in the axial direction is detachably screwed onto the rotary drag body 203, and the minimum diameter of the through hole in the spool 209 is dragged. It is configured to be larger than the maximum diameter of the knob 207.

According to the spinning reel having the above structure, when the drag washer is replaced, the rotary drag body having the spool screwed therein is slidably attached to the fixed drag body, and the drag washer is mounted between the drag bodies. Therefore, if you remove the drag knob from the spool shaft and pull out the spool, the rotating drag body is pulled out together with the spool, which exposes the drag washer and allows you to easily replace the drag washer. It was Also, when replacing the spool, it is possible to remove only the spool without removing the drag knob because the spool is screwed into the rotary drag body, and it is now possible to prevent the drag knob from being lost. .

[0006]

However, in the spinning reel configured as described above, the trouble of exchanging the drag washer can be eliminated, but the drag knob must be removed, so the drop of the drag knob occurs when exchanging the drag washer. The problem of loss has occurred. Furthermore, since the diameter of the drag knob screwed onto the tip of the spool shaft is smaller than the minimum diameter of the through hole in the spool, when the reel becomes smaller, the drag knob becomes smaller accordingly, and when adjusting the drag force. There was a new operational problem that the drag knob was difficult to turn.

The present invention has been made in order to solve the problems of the above-mentioned prior art. The object of the present invention is to enable replacement of the drag washer and spool without removing the drag knob. It is an object of the present invention to provide a supporting structure for a spinning reel that can easily perform variable adjustment of drag force even if the reel becomes small.

[0008]

A tubular fixed drag body is fixed to a spool shaft that moves back and forth by the rotation of a handle, and the tubular rotary drag body is freely and axially slid on the fixed drag body. Attach freely,
Further, resistance plates facing each other at the end portions of both drag bodies are integrally provided, and a drag washer is inserted between the resistance plates to form a drag body. The spool shaft has a non-circular cross-section and a tubular shape at the tip thereof. A drag adjusting body is screwed, a spring is elastically mounted between the drag adjusting body and the tip of the rotary drag body, and a spool having a through hole formed in the axial direction is detachably screwed to the drag body. A drag knob is rotatably attached to the spool tip surface while being retained, and the drag knob has a diameter at least larger than the minimum diameter of the through hole and is formed by extending the rotation operation portion to near the outer peripheral edge of the spool. In addition, a non-circular engagement hole that engages with the drag knob in a disengageable manner is formed on the rear end surface, and the minimum diameter of the through hole in the spool is made larger than the maximum diameter of the drag knob.

According to the above means, when the drag force is adjusted, when the drag knob of the spool screwed and held by the rotating drag body is rotated, the drag adjusting body screwed on the spool shaft is detachable from the drag knob. Since it is engaged with, it rotates integrally and moves while varying the urging force of the spring elastically mounted between this drag adjusting body and the rotating drag body in the drag body, and the urging force of this spring adjusts the drag force. Done. To replace the spool,
The spool can be pulled out by loosening the screw with the rotary drag body and removed, so that the spool can be replaced. When installing, reverse the above removal work. To replace the drag washer, when the drag knob is rotated in the direction of weaker drag force, the drag adjusting body screwed to the spool shaft rotates integrally, disengages from the spool shaft, and the rotating drag body is screwed to the spool. Therefore, the drag washer is pulled out integrally with the spool, and the drag washer is exposed and becomes replaceable. When installing after replacing the drag washer, the above procedure can be reversed. In any of the above-described spool replacement work and drag washer replacement work, the drag knob can be freely rotated with respect to the spool and is retained, so that the drag knob can be prevented from being lost.

Further, since the drag knob has a diameter larger than the minimum diameter of the through hole of the spool, the drag knob does not become difficult to operate even if the reel becomes small.
