Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a drag mechanism for a biaxial fishing reel with a clutch mechanism.

[Conventional technology]

In the conventional two-axis type fishing reel, the drag adjusting device is provided on the rotating shaft having the handle as the actual shaft 50.
The one disclosed in Japanese Patent No. 23584 is known.

[Problems to be solved by the invention]

However, in the drag adjusting device, the friction adjusting plate is pressed by the drag adjusting cam plate through the elastic washer, and the operating cam plate that slides the drag adjusting cam plate is used as a bearing inside the handle, that is, a bearing fixed to the side plate. Since they are rotatably fitted, the reaction force for pressing the friction plate acts on the side plates, and therefore the strength and rigidity of the side plates must be increased, which causes a problem that the weight becomes heavy.

An object of the present invention is to solve the above problems and to provide a fishing reel drag mechanism having a simple structure and being lightweight as a whole.

[Action]

In the drag mechanism of the fishing reel according to the present invention,
The drag adjusting lever is attached to the side cover of the main body, and the master gear shaft is penetrated in a substantially non-contact state. Further, the axial pressing means is provided on the main body side of the drag adjusting lever while penetrating the master gear shaft in a substantially non-contact state and abutting on the drag adjusting lever. When the drag adjusting lever is rotated to press and move the axial pressing means in the axial direction of the master gear shaft, this pressing force is given to the drag washer group via the second ball bearing. Thereby, the drag washer group,
The master gear is fixed to the master gear shaft. On the other hand, when the pressing force from the axial pressing means is released, the pressing force is not applied to the second ball bearing, so that the drag washer group slips between the master gear and the master gear shaft. Freedom. In this way, the drag force can be adjusted.

The reaction force that pushes and moves the axial pressing means is received by the drag preset screw. Since the drag preset screw is screwed to the master gear shaft, the reaction force for pressing and moving the axial pressing means is applied to the master gear shaft. Therefore, the reaction force is not applied to the side cover of the main body to which the drag adjusting lever is attached. This can reduce the strength and rigidity of the side cover of the main body.

Since the drag preset screw is screwed on the master gear shaft, it rotates together with the master gear shaft and the axial pressing means. Here, the drag adjusting lever is penetrated with the master gear shaft in a substantially non-contact state. Further, the drag adjusting lever is in contact with a second ring of the first ball bearing which is provided in a substantially non-contact state with the master gear shaft, and the axial pressing means includes the master gear shaft. It is in contact with the first ring of the second ball bearing which is provided substantially in non-contact with the shaft. Therefore, even if the drag preset screw rotates together with the master gear shaft, the drag adjusting lever and the axial pressing means do not rotate.

That is, the drag preset screw can rotate together with the master gear shaft regardless of the drag adjusting lever and the axial pressing means while receiving the reaction force from the drag adjusting lever and the axial pressing means.

An O-ring 23 is provided between the cylindrical portion 4a of the side cover 4 and the drag adjusting lever 19 in order to prevent the drag adjusting lever from loosening.
A spring washer 24 is interposed between the outside of the drag preset screw 21 and the handle 13 in order to prevent the drag preset screw 21 from loosening.

Here, the axial pressing means 18 may be a cam system shown in FIGS. 1 and 4 and a screw system shown in FIG.

That is, as shown in FIG. 3, the cam type axial pressing means 18 includes a cam 18b provided with a height difference in the axial direction on one side of the drag adjusting cam 18a and one side of the drag adjusting lever 19 on the one side. The cam portion 18c provided on the
The rotation of the drag adjusting cam 18a is formed so as to move in the axial direction.

Further, a plurality of projections 18d are provided in the axial direction on the outer circumference of the drag adjusting cam 18a, and concave grooves 4b ... that match the projections 18d are provided on the inner peripheral surface of the cylindrical portion 4a of the side lid 4, The drag adjusting cam 18a is fitted to the cylindrical portion 4a so as to move only in the axial direction without rotating the drag adjusting cam 18a.

[Effect of device]

In the drag mechanism of the fishing reel according to the present invention,
The drag adjusting lever is attached to a side plate of the main body, and the master gear shaft is penetrated in a substantially non-contact state. Further, the stepped axial direction pressing means is provided on the main body side of the drag adjusting lever by penetrating the master gear shaft in a substantially non-contact state and abutting on the drag adjusting lever. When the drag adjusting lever is rotated to push and move the axial pressing means in the axial direction of the master gear shaft, this pressing force is applied to the second
It is provided to the drag washer group via a ball bearing. Thereby, the drag washer group fixes the master gear to the master gear shaft.
On the other hand, when the pressing force from the axial pressing means is released, the pressing force is not applied to the second ball bearing, so that the drag washer group slips between the master gear and the master gear shaft. Freedom. In this way, the drag force can be adjusted.

The reaction force that pushes and moves the axial pressing means is received by the drag preset screw. Since the drag preset screw is screwed to the master gear shaft, the reaction force that pushes and moves the axial pressing means is applied to the master gear shaft, and the side cover of the main body to which the drag adjusting lever is attached is attached. The above reaction force is not applied to. Therefore, the strength and rigidity of the side cover of the main body can be reduced. This makes it possible to provide a lightweight drag mechanism as a whole.

Since the drag preset screw is screwed onto the master gear shaft, the drag preset screw rotates together with the rotation of the master gear shaft. Here, the master gear shaft is penetrated through the drag adjusting lever and the axial pressing means in a substantially non-contact state. Further, the drag adjusting lever is in contact with a second ring of the first ball bearing which is provided in a substantially non-contact state with the master gear shaft, and the axial pressing means includes the master gear shaft. It is in contact with the first ring of the second ball bearing which is provided substantially in non-contact with the shaft. Therefore, even if the drag preset screw rotates together with the master gear shaft, the drag adjusting lever and the axial pressing means do not rotate.

That is, the drag preset screw can rotate together with the master gear shaft regardless of the drag adjusting lever and the axial pressing means while receiving the reaction force from the drag adjusting lever and the axial pressing means.
Accordingly, it is possible to provide a fishing reel drag mechanism having a simple structure and being lightweight as a whole.
