  • Publication number: 20230019517
    Abstract: A reel seat of the present disclosure has a seat body including a reel leg placing portion and a tubular portion formed with an opening hole that a rear end portion of a rod is fitted in and fixed to. The seat body includes a floating hood moving in an axial direction to fix a reel leg on the reel leg placing portion, a nut member fitted in the floating hood to move the floating hood in the axial direction with the floating hood whirl-stopped, and a click mechanism provided in a fitting region between the floating hood and the nut member. The click mechanism includes a recess-and-projection formed on an inner peripheral surface of the nut member and produces click sound, and an arc-shaped recessed portion formed on an outer peripheral surface of the floating hood to install a plate spring therein. The plate spring has a top portion engaged with the recess-and-projection.

  • Patent number: 11497202
    Abstract: The present invention provides a reel leg fixing apparatus having a sufficient strength in the coupling between the operation nut and the movable hood while reducing the thickness and the weight of the movable hood efficiently and effectively. In the reel leg fixing apparatus according to the present invention, the movable hood and the operation nut are coupled together when a locking portion bent and provided at an end of the movable hood is engaged with a recess at an end of the operation nut. The movable hood is formed of a prepreg sheet as a fiber-reinforced resin member including reinforcement fibers impregnated with a synthetic resin, and the reinforcement fibers oriented at least in the axial direction extend continuously at least in a coupling between the movable hood and the operation nut.
