Patent ID: 6981668

Claim:
A drag adjustment knob for a spinning reel that adjusts a drag force of a drag mechanism that brakes a spool, the spool being rotatably mounted on a spool shaft such that a rearward movement of the spool relative to the spool shaft is restricted, the spool shaft being movable forward and backward with respect to a reel unit of the spinning reel and having a first male screw portion formed on its front end and, the drag adjustment knob comprising: a first adjustment unit that includes a first female screw portion that is adapted to screw onto the first male screw portion; a transmission unit that is adapted to be non-rotatably but axially movably mounted on the spool shaft so as to be in contact with a rear of the first adjustment unit, the transmission unit having a second male screw portion; a second adjustment unit that includes a second female screw portion that screws onto the second male screw portion; and a pressing unit that is disposed between the second adjustment unit and the drag mechanism so that the pressing unit can come into contact with both the second adjustment unit and the drag mechanism, the pressing unit being non-rotatable but axially movable with respect to the spool shaft; the number of threads of one of the first and second female screw portions that has a greater screw lead being greater than that of the other of the first and second female screw portions.
