Patent number: 6405955Abstract: A spinning-reel fishing line guiding mechanism that readily does away with fishing line entanglement. Arm section (40a) of first bail support member (40) on bail arm (34) lies within a sphere having a radius of a first distance R1 given by the maximum distance from a reference point P—which is the juncture between stationary shaft cover (46) and bail (41)—to an outer peripheral portion of the arm section 40a. The arm section (40a) is formed such that distances R1a and R1b from the reference point P to points on its outer peripheral portion become gradually shorter than, heading outward from, the first distance R1. That is, the configuration is such that distances R1b become shorter than distances R1a.Type: GrantFiled: February 2, 2001Date of Patent: June 18, 2002Assignee: Shimano Inc.Inventor: Yoshiyuki Furomoto

The rotor body 15 has a cylindrical section 20 that is rotatively fitted to the reel body 2, and that has a ring-like large-diameter portion 20a diametrically larger than the rest, and a pair of rotor arms 21 including a pair of connecting sections 21a extending diametrically outward from opposing circumferential surface positions rear-endwise on the large-diameter portion 20a and a pair of arms 21b extending forward spaced apart from the cylindrical section 20. The bail arm is pivotally fitted tip-endwise to the pair of rotor arms 21, and is for guiding and fishing line onto the spool. The rotor cover 17 is a member fitted so as to cover the large-diameter portion and external exposed surfaces of the pair of connecting sections, and to allow detachment from and reattachment to the rotor body 15.Type: GrantFiled: October 24, 2000Date of Patent: May 7, 2002Assignee: Shimano Inc.Inventors: Koji Takikura, Seiji Myojo, Masakazu Iwabuchi, Jun Sato, Yoshiyuki Furomoto
