1. A drag device for a fishing reel using fluid resistance, comprising:
a housing (3) forming an outer body;
a resistive fluid charged in a hydraulic chamber (C) within the housing (3);
a rotary blade (5) rotatably embedded in the hydraulic chamber (C) with the resistive fluid;
a rotary shaft (7) rotatably supported on the housing (3), rotatably supporting the rotary blade (5) within the hydraulic chamber (C); and
a knob (9), mounted on one side of the housing (3) for engagement with one end of the rotary shaft (7), for adjusting an angle of attack of the rotary blade (5) when rotated by an external force,
wherein, when a rotational torque greater than a predetermined drag power is applied to a spool (10) of a fishing reel axially coupled to the rotary shaft (7), the rotary blade (5) is adapted to rotate with the spool (10) in the direction of unwinding the fishing line while overcoming the fluid resistance of the resistive fluid,
wherein the rotary blade (5) is adapted to set a drag power to resist unwinding of the spool (10), by adjusting the angle of attack.
