However, since the plate-like control member is usually formed by press working, the dimensional accuracy is poor, and the flatness is also bad due to sagging and burrs.
For this reason, when the control member is locked to the handle shaft, the perpendicularity of the control member with respect to the handle shaft is poor, and when the handle shaft rotates, the control member is shaken and the teeth of the drive gear that contacts the side surface of the control member are As a result, the rotational performance of the handle may be deteriorated and smooth winding operation may not be performed.

Further, when the control member is additionally processed to obtain flatness after press working, there is a problem that the cost becomes high.
The present invention has been devised in view of such circumstances, and it is intended to provide a fishing reel that eliminates runout of teeth of the drive gear, improves the rotational performance of the handle, and enables a smooth winding operation. Objective.

  In order to achieve such an object, the invention according to claim 1 is directed to a handle shaft base that is rotatably attached to the reel body, a handle reversal prevention function at the time of fishing line feeding, or a clutch mechanism by a handle winding operation. In a fishing reel equipped with a plate-like control member that automatically returns from the clutch-off state to the clutch-on state, or a plate-like control member that has both of these functions, the coupling member is fixed to the base of the handle shaft. The control member is mounted on the handle shaft via the connecting member.

  According to a second aspect of the present invention, in the fishing reel according to the first aspect, the connecting member comprises a circular portion and a non-circular portion at the center along the outer peripheral shape of the base portion of the handle shaft. An anti-rotation fitting hole is provided, and the invention according to claim 3 is the fishing reel according to claim 1 or 2, wherein the connecting member is formed by cutting. It is characterized by.

According to the first aspect of the present invention, even if the dimensional accuracy of the control member is poor, by attaching the control member to the handle shaft via the connecting member, the drive gear is made to contact the connecting member to the handle shaft. Even if it is mounted, it is possible to suppress the vibration of the drive gear as compared with the conventional case, the rotational performance of the handle is improved, and a smooth winding operation is possible.
Further, according to the invention of claim 2, there is an advantage that high-precision detent fitting of the connecting member to the handle shaft can be reliably performed in a limited space called a detent fitting hole provided in the connecting member itself. .

According to the invention of claim 3, since the connecting member is cut out and formed with high dimensional accuracy, the connecting member is attached to the handle shaft with a good squareness.
For this reason, if the control member is mounted on the handle shaft via such a connecting member, the connecting member has good flatness even if the drive gear is mounted on the handle shaft by contacting the connecting member. It is possible to more reliably suppress the drive gear from swinging, improving the rotational performance of the handle, and enabling a smooth winding operation.

The connecting member 45 is cut out from an ingot into a thin cylindrical shape using a lathe or a milling machine, and a clutch return gear 39 is prevented from rotating on the outer periphery thereof. A non-circular fitting portion 55 to be fitted and an annular support portion 59 with which an idle gear 57 described later is in sliding contact are processed with high dimensional accuracy.
Further, at the center of the connecting member 45, there is a rotation fitting hole 65 including a circular portion 61 along the outer shape of the stopper 51 of the handle shaft 37 and a non-circular portion 63 along the outer shape of the handle shaft 37. The connecting member 45 is fitted to the base of the handle shaft 37 with a good squareness while the one side surface of the connecting member 45 is in contact with the stopper 49.

On the other hand, as shown in FIG. 2, a rotation stop fitting hole 67 is provided in the center of the clutch return gear 39 along the outer shape of the fitting portion 55. 67 is fitted and the clutch return gear 39 is integrated with the connecting member 45.
Further, as shown in FIG. 3, a drive gear (drive gear) 69 that meshes with the pinion gear 23 is rotatably attached to the handle shaft 37.

The drive gear 69 has a cylindrical shape that is open on the handle 33 side and closed on the anti-handle 33 side, and a conventionally known drag device 71 is accommodated in the cylindrical internal space.
The drag device 71 includes a washer 73 disposed so as to rotate integrally with the drive gear 69, a plurality of washers 75 fixed to the handle shaft 37, and a lining material 77 disposed therebetween. A desired drag force can be applied by pressing the washers 73 and 75 and the lining material 77 in the axial direction by operating the drag lever 79 of FIG. 1 screwed to the handle shaft 37. Yes.

  Thus, the drive gear 69 and the handle shaft 37 are frictionally coupled by the drag device 71, and the rotational force of the handle 33 is transmitted from the drive gear 69 and the pinion gear 23 to the spool shaft 17 via the drag device 71, so that the spool 19 is The rotation force of the handle 33 to the spool shaft 17 is interrupted by the rotation of the clutch lever 27 and the clutch OFF operation.

Further, as shown in FIG. 1, the handle shaft 37 is provided with a reverse rotation prevention device comprising a one-way clutch 81, and the one-way clutch 81 causes the handle shaft 37 (handle 33) to reverse when the fishing line is fed. Prevention is intended.
3, 57 is an idle gear which is rotatably attached to the base portion of the handle shaft 37 while being in sliding contact with the support portion 59 of the connecting member 45 and its side surface, and is arranged in a non-contact state with the clutch return gear 39. ing. The idle gear 57 is provided with a plurality of protrusions 85 that fit into a plurality of fitting holes 83 provided on the side opposite to the handle 33 of the drive gear 69. The idle gear 57 is always integrated with the drive gear 69. It is designed to rotate.

As shown in FIG. 1, the idle gear 57 meshes with an operating gear 89 of a level wind mechanism 87 disposed in front of the spool 19.
As in the prior art, the level wind mechanism 87 has a worm shaft 93 in which a traverse groove 91 is formed on the outer peripheral surface and an operating gear 89 is attached to the end, a cylinder 95 that accommodates the worm shaft 93, and the rotation of the worm shaft 93. And a sliding body (not shown) that slides left and right along the cylindrical body 95, and guides the fishing line to the spool 19 via a fishing line guide member provided on the sliding body.

When the handle 33 is rotated, the rotational force is transmitted from the idle gear 57 that rotates integrally with the drive gear 69 to the operating gear 89 to rotate the worm shaft 93, and in conjunction with the rotation of the worm shaft 93. The fishing line guide member reciprocates left and right together with the sliding body so that the fishing line guided by the spool 19 is evenly wound.
Since the present embodiment is configured as described above, when the clutch lever 27 is pressed downward in the clutch ON state of FIG. 2, the clutch plate 31 engaged with the annular groove 29 of the pinion gear 23 is The clutch coupling of the pinion gear 23 is released and the clutch mechanism 25 is switched to the clutch OFF.

In addition to returning to the clutch ON position, the clutch plate 31 causes the pinion gear 23 to be coupled to the clutch portion 21 by the restoring force of the coil spring, and the clutch mechanism 25 is automatically returned to the clutch ON state.

  When the handle 33 is wound up in the clutch ON state, the rotational force of the handle 33 is transmitted from the drive gear 69 and the pinion gear 23 to the spool shaft 17 via the drag device 71 and the spool 19 rotates. As described above, when the clutch lever 27 is operated to turn off the clutch, the rotational force of the handle 33 to the spool shaft 17 is cut off, but the clutch return gear 39 is cut through the connecting member 45 formed with high dimensional accuracy. The idle gear 57 is slidably contacted with the connecting member 45 attached to the base of the handle shaft 37 and attached to the handle shaft 37 with good flatness and squareness, and the drive gear 69 is connected to the idle gear 57. In addition, the level wind mechanism is connected to the connecting member 45 that is attached to the handle shaft 37 with good flatness and squareness. Since the operative gear 89 of the 7 meshes, there is no possibility to swing the drive gear 69 and differential gear 89 during the winding operation of the handle 33.

Thus, according to the present embodiment, the connecting member 45 is cut out and formed with high dimensional accuracy, and therefore the connecting member 45 is attached to the handle shaft 37 with a good squareness.
Then, by attaching the clutch return gear 39 to the handle shaft 37 through such a connecting member 45, the idle gear 57, the drive gear 69, etc. can be attached to the handle shaft 37 by contacting the connecting member 45. Since the connecting member 45 has a good flatness, according to the present embodiment, it is possible to surely suppress the swing of the idle gear 57 and the drive gear 69, and the handle as compared with the conventional fishing reel. The rotational performance of 33 is improved, and a smooth winding operation is possible.
