Spinning reel for fishing

Abstract

A spinning reel for fishing includes: a reel body including a front portion; a handle provided in the reel body; a cap-shaped cover body including a surrounding wall mounted in the front portion of the reel body; a spool on which a fishing line is to be wound; a rotor including a fishing line guide part, the rotor being rotated by the rotational manipulation of the handle to wind the fishing line on the spool; a driving part passing through the cover body and transmitting the rotation of the handle to the rotor; a support part provided in the front portion of the reel body and supporting the driving part; and a magnetic seal device mounted in the cover body and including a magnet, a cylindrical magnetic body forming a magnetic circuit between the magnetic body and the magnet and magnetic fluid maintained between the magnet and the magnetic ring.

       1. A spinning reel for fishing comprising:
 a reel body including a front portion;   a handle provided in the reel body;   a spool on which a fishing line is to be wound;   a rotor that includes a cylindrical portion accommodating the front portion of the reel body and a fishing line guide part, the rotor being rotated by the rotational manipulation of the handle to wind the fishing line on the spool, an opening being formed radially through the cylindrical portion of the rotor;   a driving part transmitting the rotation of the handle to the rotor;   a support part provided in the front portion of the reel body and supporting the driving part; and   a magnetic seal device arranged between the driving part and the support part.   
     
     
       2. The spinning reel according to  claim 1  further comprising a cap-shaped cover body including a surrounding wall mounted in the front portion of the reel body,
 wherein the magnetic seal device is mounted in a front portion of the cover body, and 
 wherein the driving part passes through the front portion of the cover body. 
 
     
     
       3. The spinning reel according to  claim 2 , wherein the magnetic seal device is arranged on a surface substantially flush with the front surface of the cover body, as not to protrude over the surface. 
     
     
       4. The spinning reel according to  claim 3 , wherein the magnetic seal device includes a magnet, a cylindrical magnetic body forming a magnetic circuit between the magnetic body and the magnet and magnetic fluid maintained between the magnet and the magnetic ring. 
     
     
       5. The spinning reel according to  claim 3  further comprising a rolling type one-way clutch allowing the rotation of the driving part in one direction and preventing the rotation of the driving part in the other direction,
 wherein the magnetic body functions as an inner race of the one-way clutch. 
 
     
     
       6. The spinning reel according to  claim 1 , wherein the opening of the rotor has a rectangular shape. 
     
     
       7. The spinning reel according to  claim 1 , wherein the rotor includes a triangle-shaped notch opening. 
     
     
       8. The spinning reel according to  claim 1 , wherein the rotor includes a pair of arms formed at opposite sides of the cylindrical portion of the rotor, and a curved reinforcing member connecting the cylindrical portion of the rotor and the pair of the arms. 
     
     
       9. A spinning reel for fishing comprising:
 a reel body including a front portion;   a handle provided in the reel body;   a cap-shaped cover body including a surrounding wall mounted in the front portion of the reel body;   a spool on which a fishing line is to be wound;   a rotor including a fishing line guide part, the rotor being rotated by the rotational manipulation of the handle to wind the fishing line on the spool;   a driving part passing through the cover body and transmitting the rotation of the handle to the rotor;   a support part provided in the front portion of the reel body and supporting the driving part; and   a magnetic seal device mounted in the cover body and including a magnet, a cylindrical magnetic body forming a magnetic circuit between the magnetic body and the magnet and magnetic fluid maintained between the magnet and the magnetic ring.   
     
     
       10. The spinning reel according to  claim 9 , wherein the magnetic seal device is arranged on a surface substantially flush with the front surface of the cover body, as not to protrude over the surface. 
     
     
       11. The spinning reel according to  claim 10  further comprising a rolling type one-way clutch allowing the rotation of the driving part in one direction and preventing the rotation of the driving part in the other direction,
 wherein the magnetic body functions as an inner race of the one-way clutch. 
 
     
     
       12. The spinning reel according to  claim 9 , wherein the rotor includes a pair of arms formed at opposite sides of the cylindrical portion of the rotor, and a curved reinforcing member connecting the cylindrical portion of the rotor and the pair of the arms. 
     
     
       13. A spinning reel for fishing comprising:
 a reel body including a front portion;   a handle provided in the reel body;   a cap-shaped cover body including a surrounding wall mounted in the front portion of the reel body;   a spool on which a fishing line is to be wound;   a rotor including a fishing line guide part, the rotor being rotated by the rotational manipulation of the handle to wind the fishing line on the spool;   a driving part passing through the cover body and transmitting the rotation of the handle to the rotor;   a support part provided in the front portion of the reel body and supporting the driving part; and   a magnetic seal device mounted in the cover body and including a magnet, a cylindrical magnetic body forming a magnetic circuit between the magnetic body and the magnet and magnetic fluid maintained between the magnet and the magnetic body,   wherein the magnetic seal device is arranged with a flat front surface thereof that is flush with a flat front surface of the cover body, as not to protrude over the surface, and wherein the magnetic seal device extends radially so that the flat front surface thereof is oriented radially between the driving part and the cover body.   
     
     
       14. The spinning reel according to claim 13, further comprising a rolling type one-way clutch allowing rotation of the driving part in a first direction and preventing rotation of the driving part in a second, opposite direction, the one-way clutch including an inner race, an outer race, and one or more rolling members disposed between the inner race and the outer race, wherein the magnetic body is configured to function as an inner race of the one-way clutch. 
     
     
       15. The spinning reel according to claim 14, wherein the inner race is made of a metallic material.
