Abstract

A dual-bearing reel includes a reel body, a spool rotatably held between side plates, and a brake unit configured to brake the spool. The brake unit includes a cover portion, a first regulator and a second regulator. The cover portion has a first circumferential part and a second circumferential part, and is mounted to the reel body. The first regulator and the second regulator are covered with the cover portion. The first circumferential part has a first opening exposing at least a part of the first regulator therethrough, whereas the second circumferential part has a second opening exposing at least a part of the second regulator therethrough. The reel body has a first restriction part covering the first opening.

First claim

What is claimed is:

1. A dual-bearing reel, comprising:
a reel body having a pair of side plates being disposed at an interval from each other;
a spool being rotatable supported between the side plates;
a spool shaft coupled to the spool so as to be unitarily rotatable the spool and
a brake unit mounted to the reel body and being configured to brake rotation of the spool,
the brake unit including
a first circumferential part,
a second circumferential part different from the first circumferential part,
a first regulator having a first exposed part and being configured to regulate a brake force within a first regulation range, the first exposed part being at least partially exposed from the first circumferential part, and
a second regulator having a second exposed part and being configured to regulate the brake force within a second regulation range, the second exposed part being at least partially exposed from the second circumferential part, the second regulation range being different from the first regulation range, and

the reel body further having a restriction part covering at least one of the first exposed part and the second exposed part.

2. The dual-bearing reel according to claim 1 , wherein
the brake unit further includes a cover portion, the cover portion being attachable to the reel body and having a first opening and a second opening, the first opening being disposed on the first circumferential part so as to expose the first exposed part therethrough, the second opening being disposed on the second circumferential part so as to expose the second exposed part therethrough.

3. The dual-bearing reel according to claim 1 , wherein
the brake unit is configured to electrically brake the spool.

4. The dual-bearing reel according to claim 1 , wherein
the first regulator includes
a first operating portion having at least one first magnet and being at least partially exposed from the first circumferential part, and
a first detector being faced to the at least one first magnet and being configured to detect a regulation position of the first operating portion.

5. The dual-bearing reel according to claim 4 , wherein
the second regulator includes
a second operating portion having at least one second magnet and being at least partially exposed from the second circumferential part, and
a second detector being faced to the second magnet and being configured to detect a regulation position of the second operating portion.

6. The dual-bearing reel according to claim 5 , wherein
the brake unit includes
a brake portion having a conductor and a brake magnet, the conductor being mounted to one of the reel body and the spool, the brake magnet being mounted to the other of the reel body and the spool so as to be at least partially faced to the conductor through a predetermined gap, and
a first shield member being disposed between the first detector and the brake magnet and shielding a magnetic flux of the brake magnet.

7. The dual-bearing reel according to claim 6 , wherein
the brake unit includes a circuit board, the circuit board being mounted to the reel body and having a first surface faced to the spool,
the brake magnet is a cylindrical magnet mounted to the spool, and
the conductor is formed by a plurality of coils, the coils being mounted to the first surface of the circuit board so as to be disposed on an outer peripheral side of the cylindrical magnet at predetermined intervals.

8. The dual-bearing reel according to claim 7 , wherein
the first shield member is mounted to at least a part of the first surface of the circuit board.

9. The dual-bearing reel according to claim 7 , wherein
the brake unit includes a stepped tubular cover member formed of synthetic resin, the stepped tubular cover member having a first cover part and a second cover part, the first cover part covering the plurality of coils, and the second cover part covering at least the first surface of the circuit board and being integrally formed with the first cover part.

10. The dual-bearing reel according to claim 9 , wherein
the first shield member includes
a first shield portion disposed on a stepped surface of the second cover part, the stepped surface being faced to the spool, and
a second shield portion disposed on the first surface of the circuit board so as to shield a region located on an inner peripheral side of the first shield portion.

11. The dual-bearing reel according to claim 7 , wherein
the brake unit includes a second shield member shielding a magnetic flux of the brake magnet, the second shield member being mounted to at least a part of a second surface of the circuit board, and being disposed at least one of between the first magnet and the second detector and between the second magnet and the first detector, the second surface being located on an opposite side of the first surface.

12. The dual-bearing reel according to claim 6 , wherein
the brake unit includes a rotation detector configured to detect rotation of the spool by variation in magnetic flux of the brake magnet.

13. The dual-bearing reel according to claim 12 , wherein
the first shield member has a cutout formed so as to surround the rotation detector.

14. The dual-bearing reel according to claim 6 , wherein
the first shield member is disposed between the second detector and the brake magnet.

15. The dual-bearing reel according to claim 6 , wherein
the brake magnet is a polar-anisotropic magnet.

16. The dual-bearing reel according to claim 15 , wherein
the brake magnet is mounted to the spool shaft by bonding so as to be unitarily rotatable with the spool shaft.

17. The dual-bearing reel according to claim 15 , wherein
the brake portion further includes
an elastic ring being contactable to an end surface of the brake magnet, and
a compression member fixed to the spool shaft and compressing the elastic ring together with the end surface of the brake magnet.

18. The dual-bearing reel according to claim 15 , wherein
the brake magnet has a recess on the end surface, and
the brake portion includes a protrusion, the protrusion being fixed to the spool shaft and being engaged with the recess.

19. The dual-bearing reel according to claim 18 , wherein
the recess is recessed on the end surface along a radial direction of the end surface, and
