A drag mechanism (29) is configured to brake rotation of a spool (10) in a fishing-line releasing direction about a handle shaft (30). The drag mechanism (29) includes a drag regulation member (3), a drag washer (37), a handle (2), a one-way clutch (34), and a cam (38). The drag regulation member (3) is configured to regulate drag force, where the drag regulation member (3) includes an operating part (40) and a regulation nut (41). The regulation nut (41) is axially movably and unitarily rotatably coupled to the operating part (40). The regulation nut (41) is screwed onto an outer peripheral surface of a tip end of the handle shaft (30). The drag washer (37) is disposed onto the handle shaft (30). The handle (2) is disposed between the drag washer (37) and the drag regulation member (3). The one-way clutch (34) is configured to prevent rotation of the handle shaft (30) in the fishing-line releasing direction. The cam mechanism (38) is configured to increase the drag force.
