Abstract

A rotor for a spinning reel is configured to rotate about a spool shaft, and includes a tubular portion and a plate-shaped portion. The tubular portion is disposed away from the spool shaft at a predetermined interval. The plate-shaped portion includes a radially outer part and a radially inner part. The radially outer part is integrated with an inner peripheral part of the tubular portion. The radially inner part extends from the radially outer part toward the spool shaft. The radially outer part has a smaller thickness than at least a part of the radially inner part.

First claim

What is claimed is:

1. A rotor for a spinning reel, the rotor configured to rotate about a spool shaft, the rotor comprising:
a tubular portion disposed away from the spool shaft at a predetermined interval in a radial direction; and
a plate-shaped portion including a radially outer part, a radially inner part, and a rib part extending from the radially inner part to the radially outer part, the radially outer part integrated with an inner peripheral part of the tubular portion, the radially inner part extending from the radially outer part toward the spool shaft, the rib part extending further in the radial direction than the rib part extends in a circumferential direction, the radially outer part having a smaller thickness than at least a part of the radially inner part.

2. The rotor according to claim 1 , wherein the radially inner part tapers such that a thickness of the radially inner part gradually reduces in a radially outward direction.

3. The rotor according to claim 1 , wherein
the radially outer part includes a first annular plate part, and
the radially inner part includes a second annular plate part and a protruding part, the second annular plate part integrated with an inner peripheral part of the first annular plate part, the protruding part axially protruding from the second annular plate part.

4. The rotor according to claim 3 , wherein the protruding part is in a truncated shape.

5. The rotor according to claim 1 , further comprising:
an arm member on an outer peripheral part of the tubular portion, wherein the rib part is on the radially inner part and the radially outer part between the spool shaft and the arm member.

6. The rotor according to claim 1 , wherein the rib part does not contact the tubular portion.

7. The rotor according to claim 1 , wherein a radial distance from the rib part to the spool shaft is less than a radial distance from the tubular portion to the spool shaft.

8. A spinning reel, comprising:
the spool shaft; and
the rotor recited in claim 1 .

9. The rotor according to claim 1 , wherein the rib part axially protrudes from the radially outer part and the radially inner part.

10. A spinning reel, comprising:
a spool shaft having an axis; and
a rotor that rotates about the axis of the spool shaft, the rotor including a tubular portion and a plate-shaped portion,
the tubular portion disposed about the spool shaft, the tubular portion including an inner peripheral part spaced apart from the spool shaft at a predetermined interval in a radial direction,
the plate-shaped portion including a radially outer part, a radially inner part, and a rib part extending radially from the radially inner part to the radially outer part, the radially outer part integrated with the inner peripheral part of the tubular portion and extending towards the radially inner part of the plate-shaped portion, the rib part extending further in the radial direction than the rib part extends in a circumferential direction,
the radially outer part having a first thickness in a direction parallel to the axis of the spool shaft, the radially inner part having a second thickness in the direction parallel to the axis of the spool shaft, the second thickness being thicker than the first thickness.

11. The spinning reel according to claim 10 , wherein the radially inner part is tapered such that a thickness of the radially inner part gradually reduces in a radially outward direction.

12. The spinning reel according to claim 10 , wherein
the radially outer part includes a first annular plate part having a uniform thickness in the direction parallel to the axis of the spool shaft, and
the radially inner part includes a second annular plate part and a protruding part, the second annular plate part continuously formed with the first annular plate part, the protruding part protruding from the second annular plate part in the direction parallel to the axis of the spool shaft.

13. The spinning reel according to claim 12 , wherein the protruding part of the plate-shaped portion has a truncated shape.

14. The spinning reel according to claim 10 , further comprising:
an arm member on an outer peripheral part of the tubular portion, wherein
the rib part is on the radially inner part of the plate-shaped portion and the radially outer part and extends radially from the spool shaft towards the arm member.

15. The spinning reel according to claim 10 , wherein a radial distance from the rib part to the spool shaft is less than a radial distance from the tubular portion to the spool shaft.
