A dual-bearing reel spool braking device is configured to brake a spool that is rotatably mounted on a reel body by centrifugal force. The dual-bearing reel spool includes at least one brake shoe, a rotating member and a brake drum. The brake shoe is arranged to apply a braking force to the spool. The rotating member is configured to rotate in conjunction with the spool. The rotating member includes a pivot shaft portion and a fixing portion. The pivot shaft portion pivotally supports the brake shoe and that movably supports the brake shoe in an axial direction of the pivot shaft portion. The fixing portion engages the brake shoe and non-pivotally fixes the brake shoe. The brake drum is arranged to selectively contact the brake shoe.
