Description

  The present invention relates to a fishing spinning reel having a rotor for winding a fishing line around a spool, and more particularly to a structure for attaching a protector to an outer peripheral portion of a rear end portion of a rotor.

  The fishing spinning reel includes a spool and a rotor rotatable with respect to the spool. The rotor has a cylindrical rotor body supported by the reel body, and a bale arm mechanism for winding the fishing line around the outer peripheral surface of the spool is provided on the rotor body.

  In this type of fishing spinning reel, the spool covers the outer side of the rotor main body, and the rear end portion forming the flange shape of the rotor main body is located between the spool and the reel main body. The rear end of the rotor body is directly exposed to the outside of the fishing spinning reel without being protected by the bail arm mechanism.

  Therefore, the rear end portion of the rotor body may be damaged by interference with rocks and stones at the fishing ground, for example, when the fishing ground is moved or actually fishing. If the rotor body is scratched, there is a problem that the strength of the rotor body is reduced or corrosion is caused.

  Conventionally, as a countermeasure, a fishing spinning reel is known in which a protector is attached to the outer peripheral portion of the rear end portion of the rotor body to prevent the rear end portion of the rotor body from being damaged (for example, Patent Document 1).

According to Patent Document 1, the protector is located on the opposite side of the bail of the bail arm mechanism and is curved in an arc shape along the outer peripheral portion of the rear end portion of the rotor body. The protector is integrally held at the rear end portion of the rotor body by hooking the locking claw portion to the rotor body and fastening and fixing both ends to the rotor body via screws.
Japanese Patent Laid-Open No. 2003-274816 (FIGS. 3 and 4)

  According to the fishing spinning reel disclosed in Patent Document 1, a dedicated screw for fixing the protector to the rotor body is required, and the number of parts increases by the amount of this screw. At the same time, every time the protector is attached to the rotor body or removed from the rotor body, the troublesome work of turning the screw using a tool such as a screwdriver is forced, which increases the number of work steps. As a result, this increases the manufacturing cost of the fishing spinning reel.

  Furthermore, when turning a screw with a tool, there is a risk that the protector may be accidentally scratched with the tool, and it is inevitable that the screw head will be exposed on the protector. There is room for improvement.

  The objective of this invention is obtaining the spinning reel for fishing which can fix a protector to a rotor main body, without using an exclusive screw.

In order to achieve the above object, a fishing spinning reel according to one aspect of the present invention is provided.
A spool supported by the reel body;
A rotor body rotatably supported by the reel body, a pair of arm portions facing each other with the rotor body interposed therebetween, and a pair of covers removably fixed to these arm portions and covering the arm portions from the outside; A rotor having
A fishing line guide device provided in the arm portion of the rotor, for guiding the fishing line to be wound around the outer peripheral surface of the spool;
A protector mounted on an outer peripheral portion of a rear end portion located behind the spool in the rotor body.

  The protector includes first and second sandwiching portions interposed between a rear end portion of the rotor body and a rear end portion of the cover, and between the first sandwiching portion and the second sandwiching portion. And an intermediate portion that covers the outer peripheral portion of the rear end portion of the rotor body, and the first and second clamping portions include the rear end portion of the rotor body and the rear end portion of the cover. The protector is fixed to the rotor body by being sandwiched between the rotors.

  According to the present invention, there is no need for a dedicated screw for fixing the protector to the rotor body. For this reason, while being able to reduce the number of parts, it is possible to improve workability when the protector is attached to or detached from the rotor body, and the manufacturing cost of the rotor can be reduced.

  Further, when the protector is fixed to the rotor body, the screw head is not exposed on the protector. Therefore, the sense of unity between the protector and the rotor body is enhanced, and when the protector is attached to and detached from the rotor body, the protector can be prevented from being damaged by the tool, and the appearance around the rotor can be maintained well.

  Accordingly, the protector 30 is fixed so as to cover the region 20 of the rear end portion 12 of the rotor body 10 via the pair of covers 24 and 25, and the region 20 is protected by the protector 30.

  According to the fishing spinning reel 1 having such a configuration, the protector 30 that protects the rear end portion 12 of the rotor body 10 includes the covers 24 and 25 that cover the arm portions 11a and 11b and the rear end portion 12 of the rotor body 10. Is fixed to the rotor body 10 by being sandwiched between the outer peripheral portions of the rotor body 10 and the rotor body 10. For this reason, the exclusive screws for fixing the protector 30 to the rotor body 10 are completely unnecessary, and the number of parts of the rotor 5 can be reduced.

  At the same time, since the protector 30 can be fixed to the rotor main body 10 together with the covers 24 and 25, an independent process of fixing the protector 30 to the rotor main body 10 can be eliminated, and the number of assembling steps of the rotor 5 can be reduced. Therefore, the workability at the time of fixing the protector 30 to the rotor main body 10 or removing it from the rotor main body 10 can be improved, and the manufacturing cost of the fishing spinning reel 1 can be reduced.

  Moreover, when the protector 30 is fixed to the rotor body 10, the screw head is not exposed on the protector 30. Therefore, the sense of unity between the protector 30 and the rotor main body 10 is enhanced, and the protector 30 can be prevented from being damaged by a tool when the protector 30 is fixed to the rotor main body 10 or removed from the rotor main body 10. Therefore, the appearance of the rotor 5 can be maintained favorably.

Therefore, foreign matters such as dust and slime are less likely to adhere to the boundary portion, and the appearance of the fishing spinning reel 1 can be maintained well.

  In addition, according to the above configuration, since the first engaging convex portion 33 of the protector 30 is hooked on the engaging concave portion 35 of the covers 24 and 25, the relative position between the protector 30 and the covers 24 and 25 is accurately determined. . At the same time, the second engagement convex portion 34 of the protector 30 is hooked in the engagement hole 36 of the rear end portion 12 of the rotor body 10, so that the relative position between the protector 30 and the rotor body 10 is accurately determined.

  In addition, the first and second sandwiching portions 31a and 31b of the protector 30 are not only sandwiched between the rotor body 10 and the covers 24 and 25, but are individually caught on the rotor body 10 and the covers 24 and 25. Therefore, the protector 30 can be reliably fixed to the rear end portion 12 of the rotor body 10.

  Therefore, the sense of unity with the protector 30, the rotor main body 10, and the covers 24 and 25 is improved, which is advantageous for maintaining the appearance of the fishing spinning reel 1 well.

The basic configuration of 1 is the same as that of the first embodiment. Therefore, in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 9, the first and second sandwiching portions 31 a and 31 b of the protector 30 have only an engagement convex portion 34 that is caught in the engagement hole 36 of the rotor body 10. For this reason, the first and second sandwiching portions 31a and 31b and the covers 24 and 25 do not have components that are hooked to each other, and the edges of the escape portions 28 of the covers 24 and 25 are simply the first and second portions. It stops at butting against the edge of the clamping parts 31a, 31b.

  Even in such a configuration, the first and second sandwiching portions 31 a and 31 b of the protector 30 can be sandwiched and fixed between the rear end portion 12 of the rotor body 10 and the covers 24 and 25. Therefore, a dedicated screw for fixing the protector 30 to the rotor body 10 can be omitted, and the same effect as in the first embodiment can be obtained.

  Moreover, in comparison with the first embodiment, the shapes of the first and second holding portions 31a and 31b can be simplified, and the cost of the protector 30 can be reduced.
