Abstract
Abstract A fishing reel comprises: a rotary frame driven by a drive mechanism; a spool supported to the front of a spool shaft; a drag mechanism provided at the rear of the spool shaft for applying a load on rotation of the spool shaft, the rotary frame rotating to wind a fishing line onto the spool, the spool being supported rotatably with respect to the spool shaft; and a slide mechanism which is provided between the spool and the spool shaft for holding the spool to the spool shaft under a load slightly smaller than the maximum load corresponding to a strength of the line wound onto the spool, so that when the line is subjected to a load greater than the spool holding load, the spool freely rotates with respect to the spool shaft.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
A fishing reel comprising: a reel body; a rotary frame supported rotatably to said reel body; a drive mechanism for driving said rotary frame; a spool shaft supported to said reel body in a manner permitting it to be movable longitudinally of said reel body and rotatable; a spool supported to said spool shaft at the front portion thereof, said spool being supported rotatably with respect to said spool shaft; a drag mechanism including means within the reel body for applying a selectable load to rotation of said spool shaft; and a slide mechanism provided between said spool and said spool shaft which holds said spool to said spool shaft under a load slightly smaller than the maximum load associated with a strength of a fishing line wound onto said spool and, when said line is subjected to a load larger than the load holding said spool, which automatically allows said spool to freely rotate with respect to said spool shaft irrespective of a load applied to rotation of said spool shaft by said drag mechanism.
Claim 2
Dependent Claim
176 words
A fishing reel comprising: a reel body; a rotary frame supported rotatably to said reel body; a drive mechanism for driving said rotary frame; a spool shaft supported to said reel body in a manner permitting it to be movable longitudinally of said reel body and rotatable; a spool supported to said spool shaft at the front portion thereof, said spool being supported rotatably with respect to said spool shaft; a drag mechanism including means within the reel body for applying a selectable load to rotation of said spool shaft; and a slide mechanism provided between said spool and said spool shaft which holds said spool to said spool shaft under a load slightly smaller than the maximum load associated with a strength of a fishing line wound onto said spool and, when said line is subjected to a load larger than the load holding said spool, which automatically allows said spool to freely rotate with respect to said spool shaft irrespective of a load applied to rotation of said spool shaft by said drag mechanism.
Claim 3
Dependent Claim
63 words
A fishing reel according to claim 1, wherein said slide mechanism comprises a first member fixed to one of said spool shaft and spool, a second member supported movably to the other and made slidable with respect to said first member, and a biasing means which biases said second member to said first member and sets a sliding load for said second member.
Claim 4
Dependent Claim
26 words
A fishing reel according to claim 2, wherein said first and second members form a clutch member, said slide mechanism being of a slide clutch type.
Claim 5
Dependent Claim
25 words
A fishing reel according to claim 2, wherein said first and second members are friction plates, said slide mechanism being of a friction clutch type.
Claim 6
Dependent Claim
28 words
A fishing reel according to claim 2, wherein said biasing means includes an adjuster for adjusting a biasing force to bias said second member to said first member.
Claim 7
Dependent Claim
29 words
A fishing reel according to claim 5, wherein said adjuster screws with an axial end of said spool shaft, said adjuster having an adapter contacting elastically with said spool.
Claim 8
Dependent Claim
46 words
A fishing reel according to claim 6 wherein said adjuster comprises a first part which screws with said axial end of said spool shaft, a second part forming said adapter, and means interposed between said first and second parts for biasing said adapter against said spool.
