Abstract
A spinning reel includes a reel body, a rotor disposed at a forward position of the reel body, an arm cam pivotably attached to one of a pair of portions of the rotor and a pivotable arm pivotably attached to the other arm portion. A bail is interposed between a line roller of the arm cam and the pivotable arm. A balancer, which is provided to the pivotable arm, has a configuration projecting on a side opposite to the bail and outwardly of the pivotable arm with respect to a direction along a pivot axis of the pivotable arm.
Claims4
A spinning reel comprising:
- a reel body (2);
- a rotor (4) disposed at a forward position of the reel body (2);
- a pair of arm portions (4A, 4A) extending form said rotor (4), disposed on said rotor (4) substantially opposite to each other with respect to the axis of rotation (X) of said rotor (4);
- an arm cam (8) pivotably attached to one of said pair of arm portions (4A);
- a line roller (10) mounted on said arm cam (8);
- a pivotable arm (9) attached to the other of said arm portions (4A);
- a bail (3) interposed between said line roller (10) and the pivotable arm (9);
- said arm cam (8) and said pivotable arm (9) being pivotable about a pivot axis (Y) substantially normal to said axis of rotation (X);
- a balancer (11) provided to the pivotable arm (9), the balancer (11) having a configuration projecting from the pivotable arm (9) on a side of said pivot axis (Y) substantially opposite to the bail (3) and disposed outwardly on the pivotable arm (9) with respect to the axis of rotation (X), said balancer being formed integrally with said pivotable arm (9).
