Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a fishing spinning reel for transmitting power from a winding drive mechanism to a parallel winding mechanism via a planetary gear mechanism.

[0002]

2. Description of the Related Art Conventionally, a fishing line parallel winding mechanism of a fishing spinning reel is driven by transmitting the power of a fishing line winding drive mechanism. The fishing line winding drive mechanism is roughly divided into a type in which a protrusion is provided on a driven gear and a groove of a slider is engaged (idle gear system), and a claw held by the slider is mounted on a driver scum shaft. There are two types: a type that engages and moves back and forth (traverse scum shaft type). Both are common in that power is obtained from the fishing line winding drive mechanism, and the power is transmitted at a reduced speed from the fishing line winding drive mechanism so as not to make the rotation of the handle heavy.

[0003] Further, as disclosed in Japanese Patent Application Laid-Open No. 11-86, for example, a configuration is known in which the amount of movement of the moving body per rotation of the rotating body is reduced, and the fishing line is efficiently wound around the spool. Preferably, the parallel fishing line winding mechanism transmits power at a lower speed than the fishing line winding drive mechanism.
However, in the configuration described in the above publication, a reduction mechanism that reduces the power from the fishing line winding driving mechanism to the parallel fishing line winding mechanism and transmits the power forms a gear on a third shaft that connects the two. It is difficult to determine the supporting position of the shaft,
It has been pointed out that it is difficult to move the shaft when setting the gear backlash, and it is difficult to assemble and increase the manufacturing cost due to the complicated structure with many parts.

[0004]

The problem to be solved is that a speed reduction mechanism for transmitting the power by reducing the power from the fishing line winding drive mechanism to the fishing line parallel winding mechanism is provided on a third shaft connecting the two. It is difficult to determine the supporting position of the shaft due to the formation of gears, and it is difficult to move the shaft when setting the backlash of the gears, and it is difficult to assemble due to the complicated structure with many parts. In addition, there is a problem that the manufacturing cost is increased.

An object of the present invention is to provide a fishing spinning reel which has good transmission efficiency, can greatly reduce speed, is easy to assemble, and has high center-to-axis accuracy.

[0006]

According to the present invention, there is provided a winding drive mechanism for winding a fishing line around a spool supported by a reel body by a winding operation of a handle, and the fishing line is attached to the spool. In the spinning reel for fishing provided with a fishing line parallel winding mechanism for parallel winding, the winding drive mechanism and the fishing line parallel winding mechanism are connected by a gear train, and a planetary gear mechanism is provided in the gear train. The gist is that the power from the winding drive mechanism is reduced via the planetary gear mechanism and transmitted to the fishing line parallel winding mechanism.

[0007]

According to the first aspect of the present invention, since the speed is reduced by the planetary gears 42, the number of gear shafts provided inside the reel body 1 can be reduced, and the accuracy of the distance between the shafts can be easily obtained. A high precision reel can be provided without extra cost. When the planetary gear 42 that performs deceleration in one axis is used,
Since power can be transmitted more efficiently than deceleration by the conventional gear train, the rotation of the handle 13 is lightened and operability is improved. The planetary gear mechanism C is easy to assemble.
