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.
Claims4
A fishline guide arrangement for guiding a fishline, said fishline guide arrangement comprising:
- a bail support member;
- a line slider supported by said bail support member;
- and
- a fishline guide roller supported by said bail support member and interposed between respective portions of said bail support member and said line slider;
- wherein:
- said fishline guide roller has 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 the fishline guide roller, the annular groove having a second axial length (l), wherein a first ratio (l/L) of the second axial length relative to the first axial length is set within a range of 0.05-0.35;
- said fishline guide roller comprising:
- a first circumferential surface located on a line slider side of the annular groove;
- a second circumferential surface providing a bottom surface of the annular groove and having a diameter smaller than a diameter of said first surface;
- a third circumferential surface located on a bail support member side of the annular groove and having a diameter larger than a diameter of said second surface;
- an inclined fishline guide surface located between said first surface and said second surface;
- a restriction wall surface located between said second surface and said third surface;
- and
- a further restriction wall surface connecting said inclined fishline guide surface to said second surface.
