Abstract
In a spinning reel for fishing, a fishline guide roller is rotatably supported on a bail support arm pivotably mounted on a rotor. The guide roller has a flattened shape such that a ratio of an axial length of the roller relative to a diameter thereof falls within 0.10-0.40. Further, the guide roller is formed with a narrow fishline guide groove so that a ratio of an axial length of the fishline guide groove relative to an axial length of the roller falls within 0.05-0.35. It is possible to make a fishline guide roller small in weight and size and to restrict axial motion of a fishline along the guide roller which, among other advantages, reduces line twist in the fishline.
Claims3
A fishline guide arrangement for guiding a fishline, said fishline guide arrangement comprising:
- a bail support member;
- and
- a fishline guide roller supported by said bail support member and having an axis and a first axial length (L) defined between opposite axial terminuses of said fishline guide roller, said fishline guide roller having an annular groove for receiving a fishline therein and restricting axial movement of the fishline along said fishline guide roller, the annular groove having a second axial length (l), wherein a ratio (l/L) of the second axial length relative to the first axial length is set within a range of 0.05-0.35,
- wherein the annular groove has an asymmetrical shape as viewed in a plane containing the axis.
A fishline guide arrangement for guiding a fishline, said fishline guide arrangement comprising:
- a bail support member;
- and
- a fishline guide roller supported by said bail support member and having an axis, said fishline guide roller having an annular groove for receiving a fishline therein and restricting axial movement of the fishline from moving axially along said fishline guide roller, the annular groove having an asymmetrical shape as viewed in a plane containing the axis,
- wherein the annular groove is defined by a wall surface orthogonal to the axis, a conical surface concentric to the axis, and a bottom surface extending between said wall surface and said conical surface.
