Spool braking device for dual bearing reel

A spool braking device for a dual bearing reel configured to brake a spool using centrifugal force, the spool rotating integrally with a spool shaft that is rotatably supported by a reel body, the spool braking device comprising:

• a brake drum disposed in the reel body and positioned alongside the spool in an axial direction in which a rotation axial center of the spool shaft extends, the brake drum including a tapered surface whose diameter is reduced towards the spool;
• and
• a rotation structure arranged between the spool and the brake drum in the axial direction,
• the rotation structure including
• a support that rotates in accordance with the spool shaft,
• a brake shoe swingably supported by the support, the brake shoe having a center of gravity arranged outside of the brake drum in a radial direction away from the rotation axial center, the brake shoe configured to contact the tapered surface of the brake drum, and
• a biasing member that biases one of the support or the brake drum towards the other one of the support or the brake drum, and
• the one of the support or the brake drum being movable in the axial direction with respect to the other one of the support or the brake drum in accordance with a balance of axial engaging force generated by the biasing member and axial separating force generated by the brake shoe acting on the brake drum in accordance with a rotational speed of the rotation structure such that one of the support or the brake drum is configured and arranged to separate from the other one of the support or the brake drum in the axial direction as the rotational speed of the rotation structure increases.
