The first drag unit (25) includes a first drag knob (30) that is immovable in a back and forth direction and rotatably mounted on an outer peripheral surface of a cylindrical portion (2d). The second drag unit (26) brakes the spool shaft in a position frontward of the first drag unit. The second drag unit includes a second drag knob (35) that is immovable in a back and forth direction and rotatably mounted on an outer peripheral surface of the cylindrical portion (2d). The switching mechanism (27) switches the first drag unit (25) between a drag enabling state and a drag disabling state.
