A dual-bearing reel includes a cover and a dial disc including an engagement groove having a first radius centered on the central shaft, and capable of adjusting a braking force of the spool is formed. A projection is fixed to a first side plate, and engages the engagement groove when the cover covers the first side plate. A guide groove is formed on the dial disc, which extends in a direction that is different from that of the arc of the engagement groove and is in communication with the engagement groove, and through which the projection is capable of passing and being detached from the dial disc. The projection is configured to be detached from the dial disc through the guide groove when the intersection point between the engagement groove and the guide groove is aligned with the projection and when the cover covers the first side plate.
