Abstract
Abstract A fishing reel is formed of a spool, a drag mechanism, a transmission which transmits rotation of the spool to the drag mechanism, and a one-way transmission mechanism mounted on the transmission for transmitting drive to the drag mechanism only when the spool rotates in a fishing line unwinding direction. The fishing reel also has a transmission switching mechanism capable of establishing a condition in which power transmission between the spool and the drag mechanism is broken.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
198 words
A fishing reel comprising: a rotatable spool shaft; a spool mounted on said spool shaft for taking up a fishing line; a drag mechanism; transmission means for establishing power transmission between said spool shaft and said drag mechanism, said transmission means including a first transmission gear associated with said spool shaft and a second transmission gear associated with said drag mechanism; a one-way transmission mechanism mounted on said transmission means for transmitting rotation of said spool to said drag mechanism only when said spool rotates in a fishing line unwinding direction; an intermediate gear displaceable between an engaged position which permits power transmission between said first and second transmission gears, and a disengaged position which prohibits power transmission between said first and second transmission gears; a pivot arm pivotable about said spool shaft and supporting said intermediate gear; and spring transmission means connected at one end thereof to said pivot arm and at least partially wound around said spool shaft, said spring transmission means transmitting rotational displacement of said spool shaft in the fishing line unwinding direction to thereby move said pivot arm in an engaging direction such that said intermediate gear is displaced toward its engaged position.
Claim 2
Dependent Claim
198 words
A fishing reel comprising: a rotatable spool shaft; a spool mounted on said spool shaft for taking up a fishing line; a drag mechanism; transmission means for establishing power transmission between said spool shaft and said drag mechanism, said transmission means including a first transmission gear associated with said spool shaft and a second transmission gear associated with said drag mechanism; a one-way transmission mechanism mounted on said transmission means for transmitting rotation of said spool to said drag mechanism only when said spool rotates in a fishing line unwinding direction; an intermediate gear displaceable between an engaged position which permits power transmission between said first and second transmission gears, and a disengaged position which prohibits power transmission between said first and second transmission gears; a pivot arm pivotable about said spool shaft and supporting said intermediate gear; and spring transmission means connected at one end thereof to said pivot arm and at least partially wound around said spool shaft, said spring transmission means transmitting rotational displacement of said spool shaft in the fishing line unwinding direction to thereby move said pivot arm in an engaging direction such that said intermediate gear is displaced toward its engaged position.
Claim 3
Dependent Claim
46 words
A fishing reel as claimed in claim 1 further comprising a changeover control member displaceably operable between a first position which prevents said pivot arm from moving in the engaging direction and a second position which permits said pivot arm to move in the engaging direction.
