By the way, the area inside the skirt portion of the rear portion of the spool is the area where the spool that moves back and forth and the rotor that rotates face each other, and due to the structure, a large gap is formed with the outside in the axial direction and the radial direction. Therefore, seawater, water, foreign matter, etc., easily enter the area inside the skirt portion during actual fishing.

In the fishing spinning reel of Patent Document 1, a waterproof sliding contact member made of rubber is sandwiched between a regulating member attached to the spool shaft and the spool, and the outer peripheral edge of the waterproof sliding contact member is held. It is in sliding contact with the rear inner peripheral surface of the spool on the rotor side. Therefore, in the fishing spinning reel of Patent Document 1, the drag setting force set by the drag acts directly on the waterproof sliding contact member, and the strength of the drag setting force changes the gripping force on the spool. In other words, the waterproof performance of the fishing spinning reel of Patent Document 1 is easily affected by the drag setting force.

In addition, since the sliding contact member for waterproofing is elastically deformed depending on the strength of the drag setting force, there is a possibility that the axially regulated position of the spool may be slightly displaced in the axial direction, which may affect the winding state of the fishing line wound on the spool. There is
