Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more particularly, to a braking device that applies a braking force to a drive gear provided on a handle shaft.

[0002]

2. Description of the Related Art Generally, a fishing reel is provided with a braking device for applying an adjustable braking force to a drive gear provided on a handle shaft. That is, in the dual-bearing reel, the braking member is arranged so that it can be frictionally engaged with the drive gear provided on the handle shaft driven by the handle, and the pressure contact force of the braking member with respect to the drive gear is adjusted. The braking force between the handle shaft and the drive gear is adjusted.

By the way, the drive gear has a structure in which it is meshed with a spool pinion and winds under a heavy load, so that a high-strength material is selected for the tooth portion of the drive gear. Therefore, the cylinder portion that is integrally formed with the drive gear and that houses the braking member is also formed of the same material, which is expensive in terms of material and difficult to process, resulting in an increase in overall manufacturing cost and weight. Will also increase.

Therefore, the cylindrical portion for accommodating the tooth portion and the braking member is formed separately so that different materials can be selected,
These two members, techniques detent fixed by fitting the pin from the axial direction is disclosed in JP USP264693 9.

[0005]

However, since the cylindrical portion is sandwiched by the locking member on the surface of the drive gear to lock the rotation of the drive gear, the axial length on the handle side becomes longer, and the reel as a whole becomes longer. The size is increased and the weight is biased toward the handle side, resulting in poor winding operability. Further, since the cylindrical member is a separate member from the drive gear and the pins are axially fitted and locked to fix the both, the number of parts is large and the assemblability is poor.

Further, since a waterproof structure is not provided between the drive gear and the shaft portion, a sufficient waterproof function cannot be exerted in fishing used in an environment where seawater, water, etc. easily enter.

It is an object of the present invention to provide a braking device for a fishing reel which applies a braking force to a drive gear without reducing the axial length and reducing the number of parts. . Furthermore, it aims at providing the braking device which can fully exhibit a waterproof function.

It is rotatably supported in a state in which it does not come off, and the front end side is rotatably supported by the right side plate 2b by a bearing 32 via a pressing body described later. A reverse rotation preventing gear 33 is fitted on the base end side of the handle shaft 12 so as not to rotate, and the reverse rotation preventing claw 34 engages with the reverse rotation preventing gear 33 to prevent the reverse rotation of the handle shaft 12. The drive gear 15 is rotatably supported on the handle shaft 12 at a position adjacent to the reverse rotation prevention gear 33 with a washer interposed. A circumferential groove 12a is formed on the outer peripheral surface of the handle shaft 12 at the portion where the drive gear 15 is located, and a sealing material 38 made of an elastic material is wound around this portion to provide a space between the two. It is sealed.

The drive gear 15 has external teeth 15a formed on its outer peripheral portion so as to mesh with the pinion 7. Further, an annular recess 15b is formed on the side surface of the drive gear 15, and a non-circular portion 15d is formed in a central boss portion 15c defining the recess 15b. The annular recess 15b is fitted with a base portion 45a of an accommodating cylinder portion 45 that accommodates a braking member 40 that frictionally engages the drive gear 15 with the handle shaft 12. A non-circular portion 45b corresponding to the non-circular portion 15d is formed on the inner peripheral portion of the base portion 45a.
5 is integrated with the rotation prevention. As shown in the figure, the annular recess 15b has a depth such that the base portion 45a is completely embedded so that the tubular portion 45 does not become longer in the axial direction, and the surface portion of the base portion 45a and the drive gear 1 are provided.
The side surface of 5 is substantially flush with the surface of the side, and both are integrated. An elastic member 46 is interposed between the outer peripheral surface of the base portion 45a and the annular recess 15b, and the drive gear 15
The housing tubular portion 45 is elastically fitted to prevent the occurrence of backlash between the two.

A circumferential groove 12c is formed on the outer peripheral surface of the handle shaft 12 at the portion where the pressing body 47 is located, and a sealing material 48 made of an elastic material is wound around this portion to seal between the two. ing. In addition, the storage cylinder portion 4
A seal member 55 made of a cap-shaped elastic material is attached to the tip of the member 5 so as to seal between the housing cylinder 45 and the pressing body 47 in a state of being rotatable relative to the pressing body 47. There is.

On the tip end side of the handle shaft 12, a screw portion 12 is provided.
d is formed, and a drag washer 50 that contacts the pressing body 47 is arranged in this portion, and a drag adjusting body 52 that presses the drag washer 50 is screwed. As a result, by rotating the drag adjusting body 52, the pressing body 47 is advanced and retracted along the axial direction, and the drive gear 15 receives a desired braking force (via the braking member 40 pressed by the pressing body 47). Frictional engagement force) is applied.

As described above, since the base portion 45a is formed in the accommodating cylinder portion 45 accommodating the braking member 40, and the base portion is fixed to the side portion of the drive gear 15 so as not to rotate, the teeth are integrated. Different materials can be selected for the portion 15a and the housing tubular portion 45, and the size of the handle axial direction can be prevented from increasing with a simple structure. Particularly, since the base portion 45a of the housing tubular portion 45 is embedded in the drive gear so as to be substantially flush with the side surface of the drive gear 15, the housing tubular portion 4 is formed.
The amount of protrusion of 5 in the axial direction is suppressed, and since the elastic member 46 is interposed between the fitting portions of both, there is no backlash and the fitting is ensured. Further, according to the above configuration, since the housing cylinder portion 45 can be easily attached to and detached from the drive gear 15, replacement of the braking member 40 (maintenance when worn, use conditions) without removing the drive gear 15. (Switching to a braking member having suitable characteristics) can be easily performed, and damage to the tooth portion 15a can be prevented.

In addition, the seal materials 38 and 48 wound around the handle shaft 12 and the seal material 55 mounted between the pressing body 47 and the accommodating cylinder portion 45 allow seawater to flow along the handle shaft 12 and the pressing body 47. , Water, etc. invades the braking member 4

That is, the sealing member 38, 48, 55 described above brings the braking member 40 arranged in the housing tubular portion 45 of the drive gear 15 into a completely sealed state. In this case, the seal members 38 and 48 are wound inside the circumferential grooves 12a and 12c formed in the handle shaft 12, so that the drive gear and the pressing body are prevented from becoming large in the radial direction, and the gearbox of the gear box is suppressed. Can be miniaturized. Moreover, since the weight of the braking device is reduced by this, the left and right balance of the reel unit 1 is improved, and the fishing operability can be improved.

The inside of the cylindrical housing portion 45 has sealing members 38, 4
Since it is sealed by 8, 55, oil does not leak even if an oil-impregnated lining material is used in addition to the dry type lining material such as asbestos or Teflon which is usually used. That is, since the oil-impregnated lining material can be used, the braking device can maintain smooth braking characteristics and suppress heat generation. Examples of the material of such oil-impregnated lining material include felt,
Woven cloth such as leather, cork, and carbon can be used.
