Description

  The present invention relates to a fishing reel, and more particularly to a fishing reel having a handle for winding a spool supported between side plates of a reel body.

  Conventionally, fishing reels such as dual-axis reels and electric reels have a handle shaft attached to the reel body, and the base end portion (insertion end) of the handle shaft is a bearing on the reel body frame. The handle mounting side of the handle shaft is rotatably supported via a bearing on a support portion provided on the side plate of the reel body.

  The handle shaft is equipped with an anti-reverse mechanism that allows the handle shaft to rotate forward in the winding direction and prevents reverse rotation in the fishing line feeding direction. In order to improve the picking performance, a reverse rotation prevention mechanism using a wedge action of a rolling one-way clutch is known from Patent Document 1 and the like.

In addition to the reverse rotation prevention mechanism, a drive gear that transmits the handle winding driving force to the spool is frictionally coupled to the handle shaft via a drag mechanism. In order to prevent the brake mechanism of the drag mechanism from being rotated and fitted so as to be movable in the axial direction of the handle shaft, the handle shaft has, for example, two flat portions on the outer periphery extending from the base end side to the protruding side of the side plate. It has a non-circular cross-sectional shape provided parallel to the axial direction, and the non-circular outer peripheral portion of the handle shaft is rotatably supported by a support portion on the reel body side via a bearing. A cylindrical clutch ring with which a rolling member (roller) of the clutch is slidably contacted is non-rotatably fitted to the non-circular outer peripheral portion of the handle shaft so as to be movable in the axial direction.
Japanese Patent No. 3525063

  Thus, the conventional handle shaft has a non-circular cross-sectional shape from the base end portion side to the side plate outer projecting end.

  However, in the production of the handle shaft, the flat part of the non-circular outer periphery of the handle shaft is difficult to obtain a high-precision concentricity with no deviation from the handle shaft core, and the non-circular outer periphery and the bearing When the fitting contact area is reduced, there is a possibility that backlash occurs in the fitting portion between the two, and the rotational performance of the handle shaft, that is, the meshing performance and durability between the drive gear and the pinion gear may be hindered.

  Furthermore, the clutch ring is biased and the contact state with the rolling member is not stable, which causes a hindrance to the wedge action of the rolling one-way clutch and causes reverse rotation failure (stopper back). Problems remain such as poor durability of the rolling one-way clutch.

The present invention has been devised in view of such circumstances, ensuring good stopper performance of a reverse rotation prevention mechanism using a rolling type one-way clutch, and at the same time, good engagement between the drive gear and the pinion gear on the handle shaft. An object of the present invention is to provide a fishing reel that ensures performance .

In order to achieve such an object, according to a first aspect of the present invention, a base end portion of a handle shaft and a handle mounting side are rotatably supported via bearings in one side plate of a reel body. An anti-reverse mechanism consisting of a rolling type one-way clutch is mounted on the shaft, and a cylindrical clutch ring with which the rolling member of the anti-reverse mechanism slides is non-rotatably fitted on the outer periphery of the handle shaft so as to be movable in the axial direction. In the fishing reel, a circular outer peripheral fitting portion and a non-circular outer peripheral fitting portion are provided in the axial direction on the outer periphery of the handle shaft to which the clutch ring is attached from the base end side toward the handle mounting side. The inner periphery of the clutch ring is provided with a circular inner peripheral fitting portion that fits into the circular outer peripheral fitting portion and a non-circular inner peripheral fitting portion that fits into the non-circular outer peripheral fitting portion, and On the handle mounting side of the handle shaft, A circular outer peripheral bearing support portion which is rotatably supported by a bearing provided, the circular outer peripheral fitting portion provided on the handle shaft, the non-circular outer peripheral fitting portion, the circular outer peripheral bearing support portion, and sequentially diameter to the handle-mounting side It is characterized by that.

According to the first aspect of the present invention, since the clutch ring can be fixedly fitted to the handle shaft in a state where the clutch ring is fitted and supported by the circular portions of the circular outer peripheral fitting portion and the circular inner peripheral fitting portion, the clutch ring can be attached to the handle shaft. Compared to the conventional example in which the shaft is non-rotatably fitted to the non-circular outer periphery of the shaft , the clutch ring is not biased with respect to the handle shaft (bias in the direction perpendicular to the handle shaft) and is highly accurate. As a result, the wedge action of the rolling one-way clutch (rolling member) is stable and reliable stopper performance is always obtained.

In addition, the circular outer peripheral bearing support provided on the handle shaft is rotatably supported on the side plate via the bearing, so that it is likely to occur at the corners of the non-circular outer periphery of the handle shaft due to manufacturing, handling or usage. For example, it is possible to avoid the occurrence of a problem that makes it difficult to fit in the bearing.

Furthermore , good engagement between the drive gear and pinion gear is maintained and durability is improved, and the stopper performance utilizing the wedge action of the rolling one-way clutch is further improved and stabilized by improving the accuracy of the handle shaft. Has the advantage of
And since the circular outer periphery fitting part, the non-circular outer periphery fitting part, and the circular outer periphery bearing support part provided on the handle shaft are formed in a small diameter sequentially toward the handle mounting side, the rolling type one-way clutch, clutch ring, bearing, etc. It has the advantage that it can be easily assembled.

Has been.

  Thus, as shown in FIG. 3, each of the non-circular outer periphery fitting portions 47, 57, 66, 75 is a non-circular shape in which two planes are formed in parallel on the outer periphery along the axial direction of the handle shaft 37. The outer peripheral shape. Then, from the non-circular outer periphery fitting portion 47 on the flange-shaped base 43 side to the screw portion 73 on the side plate outer projecting end side, the circular outer periphery fitting portion 53, the non-circular outer periphery fitting portion 57, the circular outer periphery fitting portion 65, The non-circular outer periphery fitting portion 66 and the circular outer periphery bearing support portion 69 are successively reduced in diameter so that the ratchet 45, the drive gear 51, the rolling one-way clutch 59, the clutch ring 63, the bearing 67, etc. can be easily assembled. It has become.

  On the other hand, as shown in FIGS. 2 and 4, the clutch ring 63 has a circular inner peripheral fitting portion 77 and a non-rotating portion corresponding to the circular outer peripheral fitting portion 65 and the noncircular outer peripheral fitting portion 66 of the handle shaft 37. A circular inner circumference fitting portion 79 is provided, and the clutch ring 63 has a circular outer circumference fitting portion 77 fitted to the circular outer circumference fitting portion 65 and a non-circular inner circumference fitting portion 66 to the noncircular outer circumference fitting portion 66.

In FIG. 2, reference numeral 85 denotes a restricting washer that restricts the radial displacement of the lining washer 49.

  The ratchet 45 fitted to the non-circular outer periphery fitting portion 47 is prevented from rotating in the reverse direction of the handle shaft 37. In addition to functioning as a reverse rotation preventing member, the ratchet 45 can be operated in a spool-free state (clutch OFF) is a component of a return device that automatically returns the spool 19 to the fishing line winding state (clutch ON). When the handle 33 is rotated in the fishing line winding direction in the clutch OFF state, the spool 19 is locked to the ratchet 45. The clutch lever 31 is returned to the clutch ON position by the engaging member and the clutch actuating member 87 that are not operated, and the clutch plate 31 is engaged with the pinion gear 23 and the clutch portion 21 by the spring force of the coil spring (not shown), so that the spool 19 is changed. It automatically returns to the thread winding state (clutch ON).

  The drive gear 51 is fitted to the circular outer circumference fitting portion 53 adjacent to the non-circular outer circumference fitting portion 47 so as to be rotatable and movable in the axial direction of the handle shaft 37. The lining washer 49 and the brake plate 55 constituting the drag mechanism 89 are in contact with each other. The brake plate 55 is fitted to the circular outer circumference fitting portion 53 and the non-circular outer circumference fitting portion 57, and is fitted to the rotation of the handle shaft 37 so as to be movable in the axial direction.

  In this fishing line winding state, the reverse rotation in the fishing line feeding direction of the handle shaft 37 is prevented by the wedge action of the rolling one-way clutch 59. As described above, Instead of the conventional structure in which the clutch ring is fixed to the non-circular outer peripheral portion of the handle shaft so as to be movable in the axial direction, the circular outer peripheral fitting portion 65 and the non-circular fitting portion 65 are not attached to the handle shaft 37 as shown in FIGS. A circular outer periphery fitting portion 66 is provided, and correspondingly, the clutch ring 63 has a circular inner periphery fitting portion 77 that fits the circular outer periphery fitting portion 65, and the non-circular outer periphery fitting portion 66. Since the circular inner periphery fitting portion 79 is provided so as to prevent rotation, the clutch shaft 63 is fitted and supported by the circular portions of the circular outer periphery fitting portion 65 and the circular inner periphery fitting portion 77. It will be possible to engage with the detent.

Compared to the prior art, the bias of the clutch ring 63 with which the roller 61 of the rolling one-way clutch 59 is slidably contacted with respect to the handle shaft 37 (bias in the direction perpendicular to the handle shaft 37) is eliminated, and highly accurate concentricity is obtained. As a result, the wedge action of the rolling one-way clutch 59 (roller 61) is stable, and reliable stopper performance is always obtained.

  Further, the handle shaft 37 has a circular outer periphery fitting portion 53, a non-circular outer periphery fitting portion 57, a circular outer periphery from the non-circular outer periphery fitting portion 47 on the flange-shaped base portion 43 side to the screw portion 73 on the side plate outer projecting end side. Since the fitting portion 65, the non-circular outer periphery fitting portion 66, and the circular outer periphery bearing support portion 69 are successively reduced in diameter, the handle shaft 37, the ratchet 45 attached to them, the drive gear 51, the rolling one-way clutch 59, the clutch Assembling of the ring 63, the bearing 67 and the like can be easily performed, and the assembling accuracy is improved.
