Spinning reel having a sealed front drag mechanism

A drag mechanism of a spinning reel comprising:

• a spool rotatably mounted on a spool shaft, a hollowed spool portion being defined on one side of said spool;
• a cylindrical member substantially housed in said hollowed spool portion, said cylindrical member being rotatable coaxially and integrally with said spool, said cylindrical member having a chamber comprising an interior side wall substantially parallel to said axis of said spool shaft and a bottom wall normal to said axis;
• friction means, in contact with said bottom wall, for applying a braking force to relative rotation between said spool and said spool shaft, said friction means being axially movably supported on said spool shaft;
• a closing disc for closing said chamber, said closing disc being in contact with said friction means and being axially movably supported on said spool shaft, said closing disc having a first seal member in contact with said interior side wall;
• an adjuster member provided on an end portion of said spool shaft, said adjuster member adjusting a pressure force of said closing disc and said friction means against said bottom wall of said cylindrical member by being axially displaced with respect to said spool shaft.
