Spinning-reel bail-tripping device

A spinning reel, comprising:

• a handle;
• a reel unit rotatably carrying said handle;
• a rotor rotatably carried on a front portion of said reel unit so as to be rotatable in a line-retrieving direction, said rotor including
• a rotor unit,
• a bail arm mounted on a fore end of said rotor unit so as to be pivotable between a line-releasing posture and a line-retrieving posture, and
• a bail-tripping mechanism mounted on said rotor unit for returning said bail arm from the line-releasing posture into the line-retrieving posture as said rotor rotates in the line-retrieving direction, said bail-tripping mechanism including
• a shifting member furnished on said rotor and having a fore end that is pivotably interlocked with a first portion of said bail arm and a rear end that is shiftable between a first position and a second position as said bail arm pivots, the first position being parted away from the reel unit and corresponding to the line-retrieving posture, the second position adjoining the reel unit and corresponding to the line-releasing posture,
• a toggle-spring mechanism having a fore end that is pivotably interlocked with a second portion of said bail arm that is different from the first portion, said toggle-spring mechanism defining a dead point and urging and toggling said bail arm between the line-retrieving and line-releasing postures,
• a switching portion provided on a front portion of said reel unit and having a first inclined face that includes upstream and downstream ends relative to the line-retrieving direction of said rotor, said downstream end projecting from said upstream end and continuing onto a peak edge, said first inclined face coming into contact with said rear end of said shifting member in the second position when said rotor rotates in the line-retrieving direction, such that said shifting member passes beyond the dead point of said toggle-spring mechanism and moves toward the first position, and
• restraining means furnished in between said bail arm and said rotor, for restraining said bail arm from returning to the line-retrieving posture when said bail arm is in the line-releasing posture, and for releasing the restraint before said rear end of said shifting member reaches said downstream end of said first inclined face as said rotor rotates in the line-retrieving direction while said bail arm is in the line-releasing posture;
• and
• a spool onto a circumferential surface of which fishing line winds, said spool being disposed on a front portion of said rotor so as to be shiftable in a front and rear.
