DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish provided with a spool reciprocating mechanism for converting the rotational operation of a handle mounted on the reel body into a reciprocating motion of the spool. The present invention relates to improvement of a spinning reel for fishing.

[0002]

2. Description of the Related Art In a spinning reel for fishing, a rotor having a fishing line guide is rotated in conjunction with a rotating operation of a handle, and a spool shaft having a spool at a tip is moved back and forth. Then, the fishing line is wound around the spool.
A reciprocating mechanism for rotating the handle through a pinion meshing with a drive gear attached to the handle shaft and converting the rotary motion of the handle into a forward and backward motion of the spool is disclosed in, for example, Japanese Patent Application Laid-Open No. 8-154543. A motion gear system having an eccentric convex portion and a traverse cam shaft system disclosed in JP-A-9-248107 are generally known. As described above, the fishing spinning reel has a configuration in which the spool shaft reciprocates back and forth in the reel body accommodating the winding drive mechanism. Therefore, the handle shaft having the drive gear and the drive gear are provided. With a configuration (offset) that is opposed to and separate from the spool shaft that passes through the inside of the meshing pinion so as to be able to move back and forth, a sufficiently stable meshing state cannot be obtained and the transmission of force is performed. Problems have been pointed out, such as a decrease in efficiency and an increase in the size of the reel body in the vertical direction.

[0003]

A problem to be solved is that a handle shaft having a drive gear and a spool shaft inserted through a pinion meshing with the drive gear so as to be able to move back and forth are intersecting each other. In such a case, a sufficiently stable meshing state cannot be obtained, and the transmission efficiency of the force deteriorates, and the reel body becomes large in the vertical direction. .

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, an object of the present invention is to improve the force transmission efficiency by reducing the distance between the handle shaft and the spool shaft so that the drive gear and the pinion are in a sufficiently stable meshing state. The object of the present invention is to provide a fishing spinning reel having a reduced size of the reel body.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention according to a first aspect of the present invention is directed to a spur having a spool at a tip end via a reciprocating mechanism having a slider for rotating a handle shaft. A drive gear on the handle shaft is engaged with a pinion that converts the spool shaft into a forward and backward motion and that fixes a rotor having a fishing line guide so as to rotate integrally with the spool shaft and inserts the spool shaft therein. In the fishing spinning reel driven to wind and retract, the outer width of the back and forth reciprocating region opposed to the handle shaft at the rear of the spool shaft is smaller than the outer width supported by the pinion and inserted and guided. The gist is that it has been formed.
