[Problems to be solved by the invention]
In the conventional reciprocating device, since the stepped gear exerts a large force particularly on the large-diameter gear, the gear shaft provided on the reel body is formed thick in order to keep the supporting strength of the large-diameter gear high. It is possible. However, if the gear shaft is formed thick, the gear shaft of the small-diameter gear disposed concentrically with the large-diameter gear also becomes thick. If the gear shaft of the small-diameter gear is formed thick, the root diameter of the small-diameter gear may be insufficient.
[0006]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a reciprocating mechanism for a spinning reel, in which the support strength of a large-diameter gear is maintained high while the root diameter of a small-diameter gear is sufficiently secured.
[0007]

The stepped gear is a large-diameter gear that is at least partially mounted on the large-diameter gear shaft provided on the reel body and meshes with the drive gear, and a small-diameter gear shaft that is provided at the end of the large-diameter gear shaft and has a smaller diameter than the large-diameter gear shaft. And a small-diameter gear that is coaxially arranged with the large-diameter gear and that rotates together with the large-diameter gear. The moving means has a driven gear that meshes with the small-diameter gear, and is means for reciprocating the spool by rotation of the driven gear.
[0008]
In this reciprocating device, when the handle rotates, the drive gear rotates in conjunction therewith. When the drive gear rotates, the rotation is transmitted to the large-diameter gear of the stepped gear, and the small-diameter gear rotates together with the large-diameter gear. When the small diameter gear rotates, the rotation is transmitted to the driven gear, and the spool reciprocates by the moving means. The large-diameter gear is mounted on a large-diameter gear shaft, and the small-diameter gear is mounted on a small-diameter gear shaft smaller in diameter than the large-diameter gear shaft. Here, at least a part of the large-diameter gear is attached to the large-diameter gear shaft, so that the supporting strength of the large-diameter gear can be kept high. Further, the small-diameter gear is mounted on a small-diameter gear shaft smaller in diameter than the large-diameter gear shaft, so that the root diameter of the small-diameter gear can be sufficiently ensured.

The spool shaft is mounted on the slider so as to be at least immovable in the forward and backward directions. In this case, since the rotation shaft of the pinion gear, which is the drive gear, which extends forward and backward, and the rotation shaft of the stepped gear and the screw shaft are arranged in parallel, it is possible to reduce the thickness by arranging them vertically. In addition, by arranging these on the left and right, the size in the upper and lower directions can be reduced.
