  • Patent number: 11737440
    Abstract: A fishing spinning reel that eliminates problems associated with line twist by providing a rotor adapted for both forward and reverse rotation wherein a drag assembly applies drag to the rotor using an adjustable cam mechanism to prevent the rotor from imparting twist on the line when in the winding mode. By enabling the rotor to rotate in a reverse direction with the application of drag the present invention prevents line twist when fighting a fish by allowing the rotor to rotate in a reverse direction to let out line and/or to remain stationary as the handle is cranked thereby preventing the rotor from imparting twist on the line.

  • Patent number: 5871164
    Abstract: In the body (6) of a spinning reel for fishing, a spool shaft (1) has a spool mounted at a tip end portion thereof and is attached to a slider (5) at a back end portion thereof. A traverse cam shaft (7) supported within the reel body has a traverse cam groove (8) provided thereon. The slider is engaged with the traverse cam groove so that the spool shaft freely slides back and forth within the reel body in association with rotation of a fishing reel handle (9). The traverse cam groove is formed so that the pitch thereof gradually increases in the longitudinal direction from a front portion of the traverse cam shaft to a rear portion thereof. The spool mounted at the tip end portion of the spool shaft has a barrel portion (2') of uniform diameter extending between a front flange portion (3) and a rear flange portion (4).

  • Patent number: 5829699
    Abstract: In a fishing spinning reel comprising a spool reciprocating mechanism adapted to convert rotation of the handle into linear reciprocating motion of the spool shaft, a non-circular part of the rear end portion of the spool shaft is locked to a slider of the spool reciprocating mechanism in such a manner that the non-circular part confronts the handle shaft. The spool shaft is non-rotatably retained, and a gap between the handle shaft and the spool shaft is minimized, whereby the reel body is decreased in size and in weight relative to conventional reels. Also transmission efficiency of transmitting drive power provided by the rotation of the handle is improved.

  • Patent number: 5775612
    Abstract: A spinning reel for fishing so designed as to offer light and smooth winding performance and to restrain the rotational clattering of a slider fixed to a spool shaft. A slider of a slide mechanism for a spool shaft is slidably fitted over a rotary shaft so that a mating part of the slider is engaged with a traverse cam groove of the rotary shaft. The slider is also fitted through its fitting hole over a guide rod extending parallel to the rotary shaft. The section of the fitting hole is formed into such a non-circular configuration as to suppress the generation of rotational clattering of the slider about the spool shaft and to provide a releasing portion in an offset direction in which the rotary shaft is offset with respect to the spool shaft.
