Abstract

The present invention provides a fishing spinning reel in which handle operation in high load winding is smooth. Specifically, the fishing spinning reel includes: a pinion gear having a rotor fixed on an end of the pinion gear and meshing with a drive gear rotationally driven by rotational operation of a handle rotatably supported on the reel body; a spool shaft inserted through the pinion gear and having a spool mounted on a front end thereof, the spool holding a fishing line wound therearound; and an oscillation mechanism configured to reciprocate the spool shaft back and forth in accordance with drive of the drive gear, wherein the spool shaft is not supported at a region from a meshing region between the drive gear and the pinion gear to a rear end of the spool shaft where the spool shaft is supported by a slidable body of the oscillation mechanism.

First claim

What is claimed is:

1. A fishing spinning reel comprising: a reel body;
a pinion gear adapted to mesh with a drive gear rotationally driven by rotational operation of a handle rotatably supported on the reel body, the pinion gear having a large interior diameter portion formed therein, the large interior diameter portion extending from the rear edge of the pinion gear beyond a meshing region between the drive gear and the pinion gear;
a spool shaft adapted to be inserted through the pinion gear;
a spool mounted on a front end of the spool shaft, wherein the spool is adapted to hold a fishing line therearound; and
an oscillation mechanism adapted to reciprocate the spool shaft back and forth in accordance with drive of the drive gear,
wherein the spool shaft is supported, at its rear end, by a slidable body of the oscillation mechanism; and
wherein the spool shaft is supported by a slidable body of the oscillation mechanism and a front inner surface of the pinion gear in front of the meshing region;
wherein the spool shaft is not supported between the slidable body and the front inner surface of the pinion gear.

2. The fishing spinning reel of claim 1 wherein the large diameter portion including the meshing region is formed to have a length of up to 80% of the entire length of the pinion gear.

3. The fishing spinning reel of claim 1 wherein the spool shaft is supported in the pinion gear at a region excluding the meshing region.

4. The fishing spinning reel of claim 1 wherein the spool shaft is supported at a plurality of positions in the pinion gear.

5. The fishing spinning reel of claim 4 wherein the spool shaft is supported at the plurality of positions in the pinion gear via collars or bearings placed between the pinion gear and the spool shaft.

6. The fishing spinning reel of claim 1 wherein the slidable body is disposed in the reel body and is supported by two guides arranged in an axial direction of the spool shaft so as to be able to move back and forth.

7. The fishing spinning reel of claim 1 wherein the pinion gear is supported on the reel body via bearings in front of the meshing region.

8. The fishing spinning reel of claim 1 wherein the pinion gear is supported on the reel body via bearings in front of and behind the meshing region.

9. The fishing spinning reel of claim 1 , wherein the large inner diameter portion has an inner diameter and a length selected such that the spool shaft, when bent under a load does not contact the inner surface of the pinion gear at the meshing region.

10. The fishing spinning reel of claim 1 , wherein the large inner diameter portion extends from the meshing region to a supporting portion in the inner surface of the pinion gear.
