Abstract

A reel part is provided for a fishing reel. The reel part includes an inner member and an outer member. The inner member has a surface treatment layer. The outer member is fixed to an outer peripheral side of the inner member. The outer member includes a processed part that is processed after being fixed to the inner member.

First claim

What is claimed is:

1. A reel part for a fishing reel comprising:
an inner member having a surface treatment layer, and
an outer member fixed to an outer peripheral side of the inner member, the outer member including a processed part that is processed after being fixed to the inner member.

2. The reel part according to claim 1 , wherein
the processed part comprises a plurality of gear teeth.

3. The reel part as recited in claim 2 , wherein
the gear teeth are machined gear teeth.

4. The reel part as recited in claim 2 , wherein
the gear teeth are casted gear teeth.

5. The reel part as recited in claim 2 , wherein
the inner member is a first metal having a corrosion-resistant layer as the surface treatment layer, and
the outer member is a second metal with a larger specific gravity and a higher rigidity than the first metal, the gear teeth are made of the second metal.

6. The reel part as recited in claim 2 , wherein
the inner member is press fitted to the outer member.

7. The reel part as recited in claim 2 , wherein
the inner member is plastically deformed to the outer member to fix the inner member to the outer member.

8. The reel part as recited in claim 2 , wherein
the inner member is bonded to the outer member.

9. The reel part as recited in claim 2 , wherein
the inner member includes a male threaded part, and
the outer member includes a female threaded part screwed into the female threaded part.

10. The reel part as recited in claim 2 , further comprising
a detent part that is installed between the inner member and the outer member and that engages with the inner member and the outer member and prevents a rotation of the inner member and the outer member.

11. The reel part as recited in claim 2 , wherein
the inner member is configured to be mounted to a drive axle that rotates in conjunction with a handle of the fishing reel, and
the gear teeth of the outer member are configured to engage with a pinion gear that rotates around a spool axis of the fishing reel.

12. A dual-bearing reel including the reel part as recited in claim 2 , and further comprising
a handle;
a drive axle operatively coupled to the handle; and
a spool that rotates around a spool axis that is parallel to an axis of the drive axle,
the inner member being mounted to the drive axle that rotates in conjunction with the drive axle,
the gear teeth of the outer member being engaged with a pinion gear that rotates around the spool axis.

13. A spinning reel including the reel part as recited in claim 2 , and further comprising
a handle;
a drive axle operatively coupled to the handle; and
a spool that rotates around a spool axis and moves forward and backward in an axial direction of the spool axis, the spool axis being transverse to an axis of the drive axle, and
the inner member being integrally and rotatably mounted on the drive axle,
the gear teeth of the outer member being engaged with a pinion gear that rotates around the spool axis.
