Rotor for a spinning reel

A spinning reel adapted to be mounted to a fishing rod, comprising:

• a handle assembly;
• a reel unit adapted to be mounted to the fishing rod and rotatably supporting the handle assembly;
• a rotor rotatably mounted on the front of the reel unit, the rotor including
• a rotor unit having
• a body portion that is mounted to the reel unit so as to be rotatable about a rotational axis, and
• first and second rotor arms that each extend forward from opposing positions on an outer peripheral surface of the body portion;
• and
• a fishing line guide portion that guides the fishing line to the spool, and is mounted only on the first rotor arm so as to be pivotable between a line-winding posture and a line-releasing posture about a pivot center;
• wherein the first and second rotor arms are formed such that a first line that is drawn along a pivot center axis of the fishing line guide portion and a second line that is drawn through a width-wise center of the second rotor arm and is substantially parallel to the first line are positioned on opposite sides of the rotational axis of the rotor;
• and
• a spool that is disposed on the front of the rotor and which moves back and forth.
