A spinning reel drag knob screwed onto a distal end of a spool shaft where a spool configured to move back and forth in a spinning reel is attached, the spinning reel drag knob being configured to regulate drag force of a drag mechanism contained in the spool, the spinning reel drag knob comprising:

• a knob member pressing a drag washer of the drag mechanism, the knob member including
• a circular rimmed portion having a knob portion formed on a front surface of the rimmed portion, the knob portion serving to regulate the drag force, and
• a cylindrical outer periphery having a diameter smaller than a diameter of the rimmed portion, the outer periphery being formed on a back side of the rimmed portion opposite the front surface;
• a nut member being disposed in the knob member and being unitarily rotatable with the knob member, the nut member being screwed onto a distal end of the spool shaft;
• and
• a sealing member including
• an attachment portion being attached to the outer periphery,
• a first sealing portion making contact with an inner peripheral surface of the spool, and
