  • Spinning reversal preventive mechanism for a reel for fishing
    Patent number: 6273351
    Abstract: A spinning reel for fishing includes a rotor rotatably supported in a reel body, a drive mechanism for driving the rotor by operating a handle mounted on the reel body, a first reversal preventive mechanism for preventing the rotor from rotating in the direction of playing out a fishline by stopping the drive mechanism from rotating in the reverse direction at the time of casting the fishline, and a second reversal preventive mechanism for holding the rotor in a predetermined position by stopping the drive mechanism from rotating in the reverse direction. The first reversal preventive mechanism is formed of a rolling one-way clutch, and the second reversal preventive mechanism is caused to hold the rotor in the predetermined position by switching the first reversal preventive mechanism to non-working condition.

  • Spinning reel with buffer for damping the return force of a bail structure
    Patent number: 6050511
    Abstract: In a spinning reel used for fishing including a rotor (3) rotatable in cooperation with rotation of a handle, the rotor supporting a bail supporting member (8) having a guide (10) for guiding a fishing line therewith, the bail supporting member (8) is able to swing between a fishing line winding position and a fishing line releasing position, the bail supporting member being biased by a spring member to position at each of the fishing line winding position and the fishing line releasing position. A backward return force produced when the bail supporting member returns to its prior position is absorbed and relaxed just before a return winding position at which the bail supporting member is returned from the fishing line releasing position to the fishing line winding position.

  • Spinning reel for fishing
    Patent number: 5954284
    Abstract: In a spinning reel for fishing, a plurality of line guide portions are formed in a line roller, so that one of the fishing line guide portions can be selected and used by changing the mounting position or mounting direction of the line roller with respect to a support member. The spinning reel for fishing with such line roller is able to cope with or use a wide variety of fishing lines having different diameters.
