The annular groove 2j for preventing intrusion of the fishing line may be formed by molding. The outer periphery of the large-diameter cylindrical section 2c provided at the front of the rotor 2 is slipped inside the cylindrical section 3c on the rear end of the spool 3.

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 fishing line is wound around a spool by rotating a rotor.

[0002]

2. Description of the Related Art Conventionally, the outer peripheral diameter of the front part of a large-diameter cylindrical part of a rotor of a spinning reel is a reel formed to be smaller than the outer peripheral diameter of a rear part as disclosed in Japanese Utility Model Publication No. 5-3014. . In the reel having this type of shape, the spool thread winding portion is likely to be deformed by the line tension of the fishing line, so that the inner diameter of the rear cylindrical portion of the spool and the outer diameter of the rear portion of the rotor cannot be close to each other. Therefore, in actual fishing, when the spool moves forward, the interval is further increased, and during the winding operation or the releasing operation of the fishing line, the slack of the fishing line, the twist of the line, the habit of the line, the wind, etc.
Troubles such as the fishing line falling on the rotor side beyond the spool rear cylindrical part and entering the inside of the spool, and further falling on the front part of the rotor and entangled with the spool shaft easily occur. There are drawbacks. In the above configuration, a thread drop prevention ring is attached to the front part of the rotor to prevent occurrence of troubles. However, there are disadvantages that the number of parts is increased and labor is required when assembling.

[0003] Further, even when the front outer peripheral diameter is not formed to be extremely small with respect to the rear outer peripheral diameter of the large-diameter cylindrical portion of the rotor as described above, as shown in Figs. Due to the draft a of the concave portion 9a of the mold 9 at the time of molding the rotor 2 ', the outer diameter of the front part is smaller than the outer diameter of the rear part of the large-diameter cylindrical part 2p of the rotor. If the outer diameter of the front part is smaller than the outer diameter of the rear part of the large-diameter cylindrical part 2p of the rotor 2 ', the more the spool moves forward in combination with the spool 3, the more the spur moves. The clearance between the inner side surface of the rear cylindrical portion 3c of the spool and the outer peripheral surface of the large-diameter cylindrical portion 2p of the rotor becomes large, and the fishing line easily enters the inside of the spool.

[0004]

The problem to be solved is that a sprue is used as it is in the form of a front-drawing mold.
If the rotor and the rotor are assembled together, the outer periphery of the rotor cylinder cannot be assembled close to the inner surface of the rear cylinder of the spool, and the draft at the time of forming the rotor cannot be obtained. As a result, the outer diameter of the front part becomes smaller than the outer diameter of the rear part of the large-diameter cylindrical part of the rotor. This makes it easier for the fishing line to penetrate the inside of the spool at the time of or during the releasing operation.

SUMMARY OF THE INVENTION In view of the above drawbacks, an object of the present invention is to form the outer periphery of a cylindrical portion formed at the front of the rotor in parallel with the spool axis so that the spool can be moved in the longitudinal movement position. It is an object of the present invention to provide a fishing spinning reel which can be uniformly brought close to the inner surface of the rear cylindrical portion.

[0006]

According to a first aspect of the present invention, a fishing line is wound around a spool via a fishing line guide provided on a rotor which rotates in conjunction with a handle. In the spinning reel for fishing, the outer periphery of a cylindrical portion formed at the front of the rotor fitted into the rear cylindrical portion of the spool is parallel to the spool axis. The gist is that it has been formed.

According to a second aspect of the present invention, the rotor is provided with a fishing line intrusion prevention portion between the inner surface of the rear cylindrical portion of the spool and the outer periphery of the cylindrical portion of the rotor. It is assumed that.

According to a third aspect of the present invention, there is provided a spinning reel for fishing in which a fishing line is wound around a spool via a fishing line guide provided on a rotor which rotates in conjunction with a handle. The outer periphery of the cylindrical portion formed at the front portion of the rotor to be fitted into the rear cylindrical portion is cut and formed into the same circumference with respect to the rotating shaft center after molding the die of the rotor. The gist is that it has been done.

According to a fourth aspect of the present invention, the outer periphery of a cylindrical portion formed at the front portion of the rotor is formed to have the same circumference as the rotating shaft center by cutting, and the cylindrical portion is formed by cutting. The gist of the present invention is that a fishing line intrusion prevention portion is provided on the outer periphery of the fishing line.

[0010]

The gap between the outer periphery of the spool 2c and the inner surface of the rear cylindrical portion 3c of the spool 3 can be made as small as possible, and can be made uniform regardless of the position of the spool 3 in the front-rear direction. At the time of the winding operation and the releasing operation, even if the fishing line falls on the rotor 2 side beyond the spool rear cylindrical portion 3c due to the influence of the slack of the fishing line, the twist of the line, the habit, the wind, etc. Does not enter gaps.

According to a second aspect of the present invention, there is provided a fishing line having a slack, a twist, a habit, and the like during a winding operation and a releasing operation of the fishing line.
