Abstract

A spinning reel includes, a spool, a spool shaft, a pinion gear, a tubular-shaped collar, a tubular-shaped nut, and an elastic member. The spool is configured to have a fishing line wound thereon when accompanied by rotation of a rotor. The pinion gear is disposed around the spool shaft and on which the rotor is non-rotatably mounted. The tubular-shaped collar is rotatably disposed on the spool shaft on an end side of the pinion gear in the axial direction of the pinion gear, and supports the spool shaft. The tubular-shaped nut is disposed to accommodate the collar and configured to screw onto the pinion gear. The elastic member is disposed between an outer peripheral surface of the collar and an inner peripheral surface of the nut.

First claim

What is claimed is:

1. A spinning reel, comprising:
a spool configured to wind a fishing line thereon;
a spool shaft configured to mount the spool;
a pinion gear disposed around the spool shaft and configured to non-rotatably attach with the rotor;
a collar rotatably disposed on the spool shaft on an end side of the pinion gear in an axial direction of the pinion gear, and supporting the spool shaft;
a nut disposed to accommodate the collar and configured to screw onto the pinion gear; and
an elastic member disposed between an outer peripheral surface of the collar and an inner peripheral surface of the nut.

2. The spinning reel recited in claim 1 , further comprising
a stopper member disposed on an end side of the collar and configured to retain the collar on the spool shaft,
the collar comprising a small-diameter portion configured to contact the end side of the pinion gear, and a large-diameter portion configured to contact the stopper portion and that is larger in diameter than the small-diameter portion, and
the elastic member being disposed between the outer peripheral surface of the collar at the small-diameter portion of collar and the inner peripheral surface of the nut.

3. The spinning reel recited in claim 2 , wherein
the stopper member is a seal member configured to seal a gap between the spool shaft and the collar.

4. The spinning reel recited in claim 2 , further comprising
a retainer disposed on an outer peripheral portion of the nut and configured to prevent the rotation of the nut,
the nut comprising a head portion accommodating the collar and a screw portion configured to screw onto the pinion gear;
the retainer comprising an extension portion extending radially inward to the head portion of the nut in the axial direction, and
the stopper member being non-movably mounted in the axial direction between the extension portion of the retainer and the nut.

5. The spinning reel recited in claim 1 , wherein
the collar comprises a large-diameter portion configured to contact the end of the pinion gear in the axial direction, and a small-diameter portion that is smaller in diameter than the large-diameter portion,
the nut comprises a stopper portion which is smaller in diameter than the large-diameter portion of the collar, and a stepped portion which is larger in diameter than the large-diameter portion of the collar,
the stopper portion of the nut is disposed facing the small-diameter portion of the collar,
the stepped portion of the nut is disposed facing the large-diameter portion of collar, and
the elastic member is disposed between the large-diameter portion of the collar and the stepped portion of the nut.

6. The spinning reel recited in claim 5 , wherein
the end side of the pinion gear and the stopper portion of the nut are configured to prevent movement of the collar in the axial direction.

7. The spinning reel recited in claim 5 , wherein
the end side of the pinion gear and the stopper portion of the nut are configured to regulate movement of the elastic member in the axial direction.

8. The spinning reel recited in claim 1 , wherein
the collar is formed from an oil-impregnated sintered metal.

9. The spinning reel recited in claim 1 , wherein
the elastic member is an O ring.
