DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a spool braking device for a fishing reel, particularly a dual bearing reel.

[0002]

2. Description of the Related Art A double-bearing type fishing reel is provided with a braking device for applying an appropriate braking force to a spool to prevent cutting of a fishing line during fishing and to facilitate correspondence with a fish. If a foreign substance such as seawater or sand during fishing adheres to the braking mechanism, the braking operation is not performed smoothly, and braking unevenness occurs or durability is reduced, so that a stable braking function cannot be exhibited. In order to protect the braking member of the drive gear provided on the handle shaft, a waterproof cover is provided outside the braking member, and a seal member is provided between the waterproof cover and the inner periphery of the drive gear and the outer periphery of the handle shaft to provide waterproofing. JP-A-63-167730, Japanese Utility Model Application Laid-Open No. 3-11
No. 3371, and the like.

[0003]

However, in the system using the waterproof cover, since the pressing action on the braking member is performed through the waterproof cover, the pressing force is dispersed and is not transmitted uniformly to the braking member, so that the braking function is efficiently performed. There is a problem that the operation cannot be performed smoothly and reliably, and the number of parts increases due to the necessity of using a dedicated waterproof cover member, and the assembling operation reduces manufacturing efficiency and increases costs.

[0004] In view of these circumstances, the present invention has improved these deficiencies and provided a preventive function for the outermost braking member constituting the braking member of the drive gear, thereby simplifying the braking mechanism and improving the braking function. SUMMARY OF THE INVENTION It is an object of the present invention to provide a fishing reel braking device for improving efficiency.

[0005]

In order to achieve the above object, the present invention provides a drive gear rotatably supported on a reel body, which is provided with a drive gear frictionally connected to a handle shaft by a braking member. The spool supported on the main body is rotatable, and the braking member is formed so as to be able to be pressed against the drive gear by a braking force adjuster screwed to the handle shaft, so that the braking force of the drive gear can be adjusted. In a fishing reel, a seal member is provided between an outermost brake body and a drive gear positioned at the outermost side, which are non-rotatably fitted to the handle shaft so as to be able to move in the axial direction, so that these can be relatively rotated. Wherein the seal member attached to the drive gear is relatively rotatable so as to come into contact with a flange-shaped sliding contact portion formed on the outer periphery of the braking portion of the outermost outer braking member. Do It is preferred.

Further, a cylindrical portion is integrally formed outside the outermost outer braking member, and an inner ring of a rolling type one-way clutch provided between the reel body and the handle shaft is formed so as to be integrally rotatable around the outer periphery of the cylindrical portion. Or when the cylindrical portion is overlapped with the inner race of the rolling type one-way clutch, the reel having this kind of rolling type one-way clutch can shorten the axial direction of the handle and simplify the structure, thereby achieving a balance. A good small and compact reel can be manufactured, and the torque of the outer braking body against the outer periphery of the handle shaft in the braking state can be distributed to the inner ring of the rolling type one-way clutch.
Biting of the handle shaft and the outer brake can also be prevented. Further, when a seal member that can rotate relative to each other is provided between the inner periphery of the base portion of the outer brake body and the outer periphery of the handle shaft, the waterproof effect can be further improved with the presence of the cylindrical portion, and a stable braking function is provided. Can be demonstrated.
