Description

  The present invention relates to a fishing reel having a clutch mechanism for switching a spool rotatably supported on a reel body between a fishing line winding state (clutch ON) and a fishing line release state (clutch OFF). Regarding improvements.

Conventionally, in a fishing double bearing type reel, a clutch mechanism for switching a spool rotatably supported by a reel body between a clutch ON state and a clutch OFF state can be found in, for example, Patent Document 1. Thus, the pinion rotatably supported by the bearing portion of the reel body can be moved in the axial direction by an external switching operation, and is engaged with the clutch engaging portion provided on the spool side (spool shaft). Although it is configured to switch off, the outer periphery of the cylindrical part on both sides of the pinion is supported by the bearing part so that it can rotate and move in the axial direction, so that smooth clutch switching action cannot be maintained due to the influence of frictional resistance, There is a problem that the lubricating oil is easily cut off at the pinion support part, the lubricity is lowered and seizure occurs, or corrosion is induced.
Therefore, Patent Document 2 proposes a configuration in which annular protrusions are formed at both ends of the pinion so as to be in partial contact with the bearing portion.
Japanese Patent No. 3215799 JP 2002-78434 A

  The problem to be solved is that the transmission and interruption of power by the clutch mechanism is performed by moving the pinion supported by the bearing in the axial direction by an external switching operation. In the case of the configuration of Patent Document 2, the pinion Due to the axial movement of the annular protrusions formed on the outer circumferences of both ends, the oil (grease, oil) lubricated to the bearing portion is likely to be reduced and removed, resulting in a seizure phenomenon that causes a decrease in lubrication performance. Or the problem of causing corrosion has not been solved.

  An object of the present invention is to provide a fishing reel that can maintain good lubricity by appropriately retaining lubricating oil between a pinion and a bearing in view of the above-mentioned drawbacks.

  According to the first aspect of the present invention, a pinion provided on one side plate of the reel body, which is supported by bearings on both sides that rotate in conjunction with a handle rotation operation, is moved in the axial direction by an external switching operation to move the spool. A fishing reel provided with a clutch mechanism that can be engaged with and disengaged from a clutch engaging portion provided on the side and switches a spool rotatably supported by the reel body between a fishing line winding state and a spool free state. The gist of the present invention is that a concave groove is formed in the axial direction on the outer periphery of the bearing portion of the pinion or on the inner peripheral side of the bearing.

According to the present invention, since lubricating oil such as grease is applied in the concave groove, the contact resistance between the pinion and the bearing is reduced, and a smooth clutch switching operation and rotating operation can be obtained. Lubricating oil is moderately held in the groove formed in the axial direction between the bearings and good lubricity can be maintained, and smooth and reliable clutch operation can be maintained.
Furthermore, the occurrence of corrosion can be suppressed by the sealing effect of the lubricating oil.
