DESCRIZIONE
A spinning reel drag knob screwed onto a distal end of a spool shaft has a knob member, a nut member and a sealing member. The knob member presses a drag washer of a drag mechanism, and includes a circular rimmed portion and a cylindrical outer periphery. The rimmed portion has a knob portion on a front surface of the rimmed portion to regulate drag force. The outer periphery is formed on a back side of the rimmed portion. The nut member is disposed in the knob member and is unitarily rotatable with the knob member. The sealing member includes an attachment portion, a first sealing portion, and a second sealing portion. The attachment portion is attached to the outer periphery. The first sealing portion contacts an inner peripheral surface of the spool, and the second sealing portion makes contact with a radial outward part of the back side.
