Abstract: A spinning reel having a line roller mechanism which directs a fishing line running from a tip end of a fishing rod toward a spool while applying a tension to a part of the fishing line, the part being bridging from the line roller mechanism to the spool. The line roller mechanism includes a first tension roller having a first axial end face and a second tension roller having a second axial end face confronting the first axial end face. The first and second axial end faces function as fishing line contact faces and define therebetween a fishing line guide groove. A distance between the fishing line contact faces becomes narrower toward the spool.

Abstract: A release preventing device for a fishing reel provided with a one-way clutch that allows a rotating body, such as the spool of a double-bearing type fishing reel and the rotor of a spinning reel, to rotate in one direction but restricts rotation of that rotating body in the other direction. Rotation is restricted in the reverse direction, the direction in which fishing line is released, by a wedge effect, wherein roller members are wedged between an inner race and an outer race.
