Description

  The present invention relates to a spool braking device that applies a braking force to a spool that is rotatably supported between side plates of a reel body, and a reverse rotation prevention that prevents reverse rotation in a fishing line feeding direction of a handle shaft that winds and rotates the spool. The present invention relates to a fishing reel provided with the device.

  2. Description of the Related Art Conventionally, a fishing reel is provided with an appropriate braking force on a spool that is rotatably supported between the side plates of the reel body to prevent cutting of a fishing line during fishing, as known in Patent Document 1, and In order to facilitate handling without trouble, a braking device is provided, and a rolling one-way clutch is installed to reduce the amount of idling in the reverse direction of the handle and improve hooking operability at the time of fish. A reverse rotation prevention device is provided between the handle shaft and the side plate of the reel body to allow forward rotation in the winding direction of the handle shaft and prevent reverse rotation in the feeding direction.

The fishing reel known in FIG. 4 of Patent Document 1 has a bearing support sealing portion on the inner side of a rotation-type fitting portion of a rolling type one-way clutch that supports a drive shaft (handle shaft). The cylindrical body that is formed to face is fixed to the support portion of the outer plate of the reel body. A cylindrical portion protrudes in the axial direction at the end of the cylindrical body, and an annular protrusion formed on one side of the drag adjusting member screwed to the drive shaft is a radial direction of the cylindrical portion of the cylindrical body. It is configured to be superposed on the outside.
Japanese Patent No. 3425255 (FIG. 4)

  The support structure of the cylindrical body fixed to the outer side plate disclosed in FIG. 4 of Patent Document 1 described above adopts a structure in which both the rolling one-way clutch and the bearing are supported by a single member. Therefore, it is possible to obtain a highly accurate concentricity, and it is possible to expect a merit in configuration that can improve both the drive shaft reverse rotation prevention function and the rotation performance.

In this support structure, a rolling type one-way clutch and a bearing are arranged in parallel in the cylinder on the drive shaft, and a drag component (a plurality of spring members) is further provided on one side of the bearing in the cylinder. , Drag adjusting members, etc.) are mounted. An annular protrusion is formed on one side of the drag adjusting member that is threadably engaged with the drive shaft in the axial direction, and this annular protrusion is formed on the radially outer side of the cylindrical portion formed on one side of the cylindrical body. Since it is arranged so as to form a gap and overlap, external force is easily applied to the annular protrusion of the drag adjustment member when moving the fishing ground or in practical use, and damage and deformation are likely to occur, and the drag adjustment member can be rotated. And the finger of the hand is likely to come into contact with the annular protrusion, and good fishing operability cannot be obtained. Further, the annular protrusion of the drag adjusting member is disposed with a gap in the axial direction on the side of the cylindrical body fixed to one side of the support that protrudes from the outer plate. The length of the drag components mounted on the shaft is increased in length in the stacking axis direction, resulting in inferior portability, large weight deviation on the handle side, poor balance, and poor fishing operability. The problem remains.

  The present invention has been made on the basis of the above-described problem, and provides a favorable braking force adjustment operation and fishing in practical use of a fishing reel provided with a spool braking device and a reverse rotation preventing device on a handle shaft. The purpose is to enable operation.

  In order to achieve the above-described object, the fishing reel according to the present invention is rotatably supported on one side plate side of the reel body and is allowed to rotate in one direction by a one-way clutch, and can rotate in the other direction. A drive gear frictionally coupled by a braking member is provided on the handle shaft to be blocked, and a spool supported between the side plates of the reel body can be rotated by the drive gear, and a braking force adjustment screwed to the handle shaft is provided. In a fishing reel in which the braking force of the spool can be adjusted by pressing the braking member by rotating the body to change the frictional coupling force of the drive gear, the rotation of the one-way clutch A support body integrally formed with a stop fitting portion, a bearing support portion of the handle shaft, and a cylindrical portion that forms an annular recess on a radially outer side of the bearing support portion is fixed to the one side plate, Characterized in that the movable annular projection formed on one side of the brake force adjusting member in the annular recess of the support in the axial direction.

According to the present invention, the annular recess of the support body integrally formed with the non-rotating fitting portion of the one-way clutch, the bearing support portion of the handle shaft, and the cylindrical portion forming the annular recess on the radially outer side of the bearing support portion. Since the structure that allows the annular protrusion of the braking force adjuster to be moved in the axial direction is adopted inside, moisture and dust attached to the outer surface of the side plate are difficult to enter the braking device by the cylindrical portion. The finger of the hand is less likely to come into contact with the annular portion of the braking force adjusting body during the rotation operation, and a favorable braking force adjustment operation can be performed.
Further, the annular protrusion of the braking force adjusting body can be moved to a range where at least a part of the annular protrusion is overlapped in the axial direction in the radially outer region of the bearing supporting the handle shaft. The length in the stacking axis direction can be shortened, the weight deviation on the handle side is reduced, the weight balance is improved, and the fishing operability is improved.

The switching member 16 provided so as to be displaceable in the vertical direction between 2b is operated to move downward so that the anti-rotation engaging portion 11a of the support member 11 to the clutch engaging portion of the pinion 15 via a known operating member. 15a is separated, the engaged state is released, and the spool 6 is switched to a fishing line releasing state (a clutch free spool free state).
When the handle 5 is rotated in the winding direction from the fishing line discharge state of the spool 6,
The pinion 15 moves to the spool 6 side through a known return mechanism (not shown) and re-engages with the anti-rotation engaging portion 11a of the support 11, and the spool 6 returns to the fishing line winding state.

A reverse rotation prevention device that allows forward rotation in the direction and prevents reverse rotation is configured. Reference numeral 20 denotes a braking force adjusting body (drag force adjusting member) screwed to the handle shaft 7 for adjusting the frictional coupling force (drag force) of the drive gear 17 so as to be able to advance and retreat.

  By rotating the braking force adjusting body 20, a leaf spring 21, a bearing 22 (bearing that supports the handle shaft 7 on the right side plate 3b), and an inner ring 23 of the one-way clutch 19 (movable in the axial direction on the handle shaft 7) are possible. And a plurality of braking members 24 are pressed against each other through a friction coupling force of the drive gear 17 with respect to the handle shaft 7, that is, a braking force applied to the spool 6 to which power is transmitted. Is adjusted.

The handle side support portion 3c of the right side plate 3b of the reel body 1 has a detent fitting portion 26a (inner circumference non-circular portion) for fixing the outer circumference non-circular portion of the outer ring 19a of the rolling type one-way clutch 19 to the rotation. A support body 26 in which a bearing support portion 26b that supports the bearing 22 and a cylindrical portion 26d that forms an annular recess 26c (space portion) on the radially outer side of the bearing support portion 26b are integrally formed (adhesion molding, It is integrated with the handle side support portion 3c of the right side plate 3b) by known means such as bonding, press fitting, caulking, screwing or the like.
