Screw holes 1i are formed at plural places outside the depressed part 1f, and the front flange member 2 is detachably attached with plural screws 7. A cylindrical projected part 2c to be fit into the inner periphery of the depressed part 1f is formed on the back surface of the front flange member 2, and the rear end surface of the projected part 2c is formed from an inner part 2e for attaching the brake plates 4 and 5 and the frictional plate 6 thereto.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel for fishing, in which a front flange portion of a spool is separately formed and a brake plate is prevented from coming off.

[0002]

2. Description of the Related Art Conventionally, when a fishing line wound around a spool is discharged, the fishing line is spirally discharged while being in contact with the outer peripheral edge of the front brim of the spool. In order to reduce the distance to improve the flight distance or to prevent the fishing line from being damaged and avoiding thread breakage, a separate ring made of wear-resistant material is fixed to the front collar of the spool. For example, Japanese Utility Model Laid-Open No. 63-36267 and Japanese Utility Model Laid-Open No. 60-194973.
It is known in Japanese Utility Model Publication No. 59-73179. or,
For example, the one provided with a front drag mechanism including a plurality of braking plates provided between the spool and the spool shaft to frictionally couple the spool to the spool shaft is disclosed in, for example, Japanese Utility Model Publication 55. −60
It is known from publication 772. In this drag mechanism, a braking plate and a seat plate are housed in a recess at the front of the spool, an annular groove is formed by cutting on the inner periphery of the opening edge of the recess, and the braking plate is prevented from coming off by a snap ring. There is.

[0003]

The problem to be solved is that the structure in which the ring formed of a separate wear-resistant material is fixed to the front brim portion of one spool is a dedicated structure only for fixing. ing. On the other hand, in the structure in which the brake plate and the seat plate are housed in the recesses to prevent them from coming off, it takes time to process the annular groove, and the snap ring is required as a slip-off prevention component. There are still problems such as high manufacturing cost.

In view of the above-mentioned drawbacks, the object of the present invention is to separately form the front flange portion of the spool and prevent the braking plate from coming off, thereby eliminating troublesome annular groove processing and assembling of a retaining ring. To reduce the number of parts and the manufacturing cost.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention forms a recess in the front portion of a spool formed of a front flange portion, a fishing line winding body portion, and a rear flange portion. Then, a braking plate for frictionally coupling the spool to the spool shaft is housed in the recess, and a fishing spinning reel capable of pressing the braking plate with an adjusting body screwed to the spool shaft. In this case, the front flange portion is formed on a separate front flange member so as to be detachably fixed to the spool front portion, and the inside of the front flange member locks the brake plate so as not to come off. .

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, since the front side flange member 2 is made of ceramics or a metal material whose surface has been subjected to abrasion resistant surface treatment, the fishing line is released without damaging the fishing line. . The front flange member 2 is detachably fixed to the front portion 1e of the spool 1, so that the brake plate 5, the friction plate 6, and the brake plate 4 are also prevented from coming off at the inner portion 2e of the rear end surface of the protrusion 2c. You can do it.
