Abstract

The invention relates to a drag device for a fishing reel using fluid resistance, comprising: a housing (3) constituting an outer body; a resistance fluid filled in a hydraulic chamber (C) in the housing (3); rotary blades (5) rotatably built in the hydraulic chamber (C) together with the resistance fluid; and a rotary shaft (7) rotatably supported by the housing (3) so as to rotatably support the rotary blades (5) in the hydraulic chamber (C), wherein when a rotational torque greater than a preset torque is applied to a spool (10) of the fishing reel shaft-coupled to the rotary shaft (7), the rotary blades (5) are configured to rotate in a direction that unwinds a fishing line together with the spool (10) while overcoming the fluid resistance of the resistance fluid. As such, when the rotary blades of the rotating shaft rotate, a drag force is generated on the spool of the fishing reel by means of shear resistance of the resistance fluid generated between the rotary blade and the resistance fluid surrounding same, such that damage or failure of a device can be greatly reduced. Therefore, it is possible to significantly increase the longevity.
