Abstract
A spinning reel rotor is rotatably mounted on a reel unit of a spinning reel for winding a fishing line onto a spool. The rotor includes a rotor unit, a bail arm, and an inertia-imparting ring. The rotor unit has a cylindrical portion that is rotatably mounted on the reel unit, and first and second rotor arms that extend forward from the rear edge of the cylindrical portion. The bail arm is pivotably mounted on the front tips of both arms, and guides the fishing line onto the spool. The inertia-imparting member is a member for providing inertia and is detachably mounted on the rotor unit. The rotor is designed to be lightweight, and can be utilized in both situations where the rotational feel is a priority, and where powering efficiency is a priority.
Claims16
A spinning reel rotor rotatably mounted on a reel unit for winding a fishing line onto a spool, said spinning reel rotor comprising:
- a rotor unit having a cylindrical portion and first and second arms, said cylindrical portion being non-rotatably coupled to a pinion gear with a nut, said pinion gear being rotatably mounted on the reel unit, said first and second arms extending forward from a rear edge of said cylindrical portion;
- a bail arm that is pivotably mounted on distal tips of both of said arms and guides the fishing line onto the spool;
- an inertia-imparting member that is a ring member detachably mounted on said rotor unit with a screw such that there is a radial gap between said inertia-imparting member and said nut and said inertia-imparting member can be detached from and attached to said rotor unit by disengaging said screw when the spool is disengaged from said rotor;
- and
- spool positioning means for positioning the spool relative to said rotor unit, said inertia-imparting member having an inner bore whose diameter is greater than an outer diameter of said spool positioning means.
