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.

Abstract: A fishline guide mechanism for a spinning reel, in which a fishline is guided within a relatively narrow groove formed in a rotatable guide roller which may be supported on a bail support member so as to be tiltable about its rotational center depending on a direction of force applied to the fishline. The groove is sized to prevent the fishline from rolling and sliding in the lateral direction (along the roller axis) when the fishline is guided by the roller, to thereby reduce twisting and tangling of the fishline.

Abstract: A line length measuring device for a fishing reel to measure the fishing line amount let out or wound based on the number of spool revolutions and has as an object the line length measurement regardless of the length of the fishing line.

Abstract: A spinning reel for fishing eliminates the accumulation of line twists in a fishline regardless of the line winding diameter on a spool. The line roller is oriented such that the diameter of a fishline guide portion of the line roller increases in the direction of rotor rotation during winding. A guide projection extending generally along a plane orthogonal to the axis of the line roller contacts the fishline to ensure the fishline is maintained at a desired position with respect to the line roller during winding. The axis of rotation for the line roller is obliquely oriented with respect to the spool shaft. The inclination of the axis of rotation for the line roller is preferably in the range of 1.degree. to 10.degree., and more preferably 2.degree. to 6.degree. from the viewpoint of attaining smooth rotation of the line roller, preventing damage of the fishline and stabilizing line control function of the guide.
