Description

[Detailed description of the invention] The means for driving or rotating the spool of a fishing reel is to slidably fit a pinion that meshes with a drive gear of a nozzle shaft onto a spool shaft having a circular joint. The clutch plate engaged with the annular groove of the pinion engages and disengages the engaging portion provided at the front of the pinion into the circular coupling portion, but the conventional pinion is as shown in FIG. Currently, a reinforcing ring is press-fitted only at the front end to reinforce the engaging portion, and the retaining annular groove of the clutch plate is cut directly into the pinion.

However, when the reinforcing ring is press-fitted only at the front end of the pinion, it tends to loosen and come off during use, and the annular groove for fitting the clutch plate is perpendicular to the cutting direction of the pinion gear, so it cannot be easily removed during cutting. There is a defect in that so-called flashing tends to occur, and the rotating action of the pinion causes wear on the clutch plate and generates noise.

This invention aims to improve these deficiencies.
A pinion that meshes with the drive gear of the bundle shaft is slidably fitted to a spool shaft having a circular coupling part using a clutch plate, and an engaging part formed on the front part of the pinion can be freely fitted into and removed from the circular coupling part. In the fishing reel thus formed, a short cylinder is fitted and fixed to substantially the front half of the pinion, and an annular groove for clutch engagement is formed on the rear side of the short cylinder.

To explain the embodiment of the present invention with reference to the drawings, the spool 1
The spool shaft 3 is fixed to the spool 1 and is rotatably supported on the reel side plates 2, 2. The spool shaft 3 is formed by a large diameter shaft 3' to which the spool 1 is fixed and small diameter shafts 3'' on both sides. is provided with a circular connecting portion 4, and the small diameter shaft 3″ is provided with a pinion 6 having an engaging portion 5 formed at the front end thereof to engage with the circular connecting portion 4.
is slidably fitted in the axial direction, and the pinion 6
A short cylinder 8 having an annular groove 7 on the rear side is press-fitted and fixed to approximately the front half of the cylinder.

Further, a clutch plate 11 which is operated by a clutch lever 9 via a clutch slide plate 10 is engaged with the annular groove 7 of the short cylinder 8 as is well known, and the pinion 6 is connected to the bundle shaft 12 via a drag mechanism 13. It meshes with the drive gear 14 that is fitted with the gear.

Preferably, the pinion 6 is made of phosphor bronze, brass, etc., and the short cylinder is made of steel, stainless steel, bonded iron, etc.

In the present invention, a short cylinder having an annular portion is fitted and fixed to approximately the front half of the pinion that engages with the missing circular joint of the spool shaft.
Unlike conventional clutch plate retaining annular grooves formed directly on the pinion, this method reliably prevents the formation of so-called cracks that prevent the rotation of the pinion, causing wear to the clutch plate 1 and generation of noise. The short cylinder that reinforces the pinion engagement part allows for smooth fishing line winding action, and is press-fitted to about half of the pinion, preventing it from falling off during use. Excellent features and practicality. It has the following.
